Background: Artocarpus heterophyllus commonly known as Kathal in Hindi and Jackfruit in English has a wide horizon of medicinal possessions. The plant is found in India and in its tropical regions. Objective: Although the plant and its extracts are renowned for its ethnic medicinal values diversely in India, yet organized data somewhere lack in reverse pharmacognostical approach of this plant that shows that plant have not been completely explored for its therapeutic potency. Materials and Methods: In the present study, the folklore potential of this plant has been explored by generating down its pharmacognostical standards along with measurement of its active therapeutic constituent ursolic acid and lupeol via. High-performance thin layer chromatography (HPTLC), evidence from organized data search says that ursolic acid and lupeol is ubiquitous to A. heterophyllus. The plant was also subjected to spectroscopic-based estimation of tannins (gallic acid and tannic acid) and flavonoids (quercetin and rutin). Antimicrobial testing was also performed. Results: Microscopic features revealed the presence of anomocytic type of stomata, collateral open type vascular bundle in which fascicular cambium is present, calcium oxalate crystal and covering trichomes were key features in leaves. Methanolic extract of leaves of the plant was subjected to HPTLC. HPTLC studies revealed that both ursolic acid and lupeol are present in appreciable amount. Plant showed good antibacterial activity which may be due to the high amount of tannins as the tannins has the ability to disintegrate the bacterial cell wall. Conclusion: The data generated could be significantly used as a reference for the authentication and quality control of A. heterophyllus.

Artocarpus heterophyllus belonging to family Moraceae is a constitutive part of common Indian diet and is freely available in Indian and neighboring continents, its medicinal properties are also mentioned in Ayurveda. It is commonly known as jackfruit in English, Kathal and Panas in Hindi, Kanthal in Bengali), Palaa in Tamil, Phanas in Gujrati and Marathi, and Chakka in Malayalam.[1] The term jackfruit is derived from the Portuguese word Jaca which, in turn, is adopted from the word “Chakka” of Malayalam-A regional Indian language.[2] This plant received a great level of scientific interest as they consist of therapeutically active secondary metabolites and is an economic source of food and widely used in traditional medicine.[3] Artocarpus species are used as traditional folk medicine in South-East Asia, Indonesia, Western part of Java and India.[4] The A. heterophyllus contains various chemical constituents as several flavones coloring matters, morin, dihydromorin, cynomacurin, and artocarpin. Triterpenic compounds such as cycloartenyl acetate, cycloartenone, and artocarpanone are also reported in the plant [5] other constituents such as β-sitosterol, ursolic acid, betulinic acid, and cycloartenone are ubiquitous throughout the plant.[6] Plant is integral part of the traditional system of medicine, it has been used conventionally, leaves are given in fever, boils, wounds, and skin ailments. The young fruits are acrid, astringent, and carminative, whereas ripen fruits are sweet, laxative, aphrodisiac, and also used as a brain tonic. The seeds are, reported to be diuretic, and constipating and wood is nervine tonic, antidiabetic, sedative and anticonvulsant.[7] A. heterophyllus is a plant that is ubiquitously distributed through India, but there is no organized literature available that may provide authentic information in the context of its therapeutic efficacy neither the justified standardization parameters are available for proper identification of the plant. Plants leaves are just used as fodder for animals due to its rich nutritional value, but the presence of secondary metabolites such as terpenoids and phenols make it a better choice as a medicinal plant rather than just being fodder for animals. The present study is an attempt to figure out the anticipated potential of this plant that has been validated by standardizing the plant in terms of its pharmacognostical standards along with measurement of its triterpenoidal constituent's ursolic acid and lupeol using high-performance thin layer chromatography (HPTLC) which is a quick analytical tool for qualitative as well as quantitative analysis of herbals. The HPTLC is more economic technique when compared to high-performance liquid chromatography (HPLC). HPTLC can run approximately 100 samples in parallel which cannot be done in HPLC where only one sample can be run at a time. Information from organized search of published literature remarks that ursolic acid and lupeol is widespread to this plant. Both of these constituents have a potent role in protecting the liver against several hepatic ailments, their antioxidant activity and ability to modulate the mitogen-activated protein kinases (MAPK) and nuclear factor-kappa B (NF-κB) signaling pathway provide it outstanding hepatoprotective activity. It significantly decreases the activation of MAPK, which, in turn, inactivates the immunoregulatory transcription factor NF-κB,[8] that is responsible for regulating gene expression that encodes the products involved in tissue damage and inflammation;[9] this protects the liver against CCl4-induced oxidative stress and inflammation by the MAPK/NF-κB pathway.

 Materials and Methods

Pharmacognostic studies

Collection and authentication

Fresh leaves and bark of A. heterophyllus were collected from the local garden of Lucknow in October 2014. Leaves were washed properly and air-dried. The collected plant material was authenticated from the National Institute of Science Communication and Information Resources (CSIR-NISCAIR) and voucher specimen number (Ref.

High-performance thin layer chromatography

Chemicals and reagents

HPTLC analyses were performed on Merck 10 cm × 10 cm HPTLC silica gel 60F254 (0.25 mm) plates. Ursolic acid and lupeol was supplied by Sigma, Aldrich, Germany. All the reagents used in the experiment were of analytical grade and were supplied by Merck, Darmstadt, Germany.

Preparation of standard solutions

Stock solutions of ursolic acid and lupeol were prepared by dissolving 0.1 mg/mL in methanol.

Sample preparation

The fresh leaves of A. heterophyllus were collected, thoroughly washed with water to remove all debris. The plant materials were shade dried and powdered by using the electric grinder at 60 mesh size. Extraction was performed by soxhlation method. First, the powdered plant material was defatted using soxhlet assembly with 250 mL of 98% petroleum ether for 24 h. This was followed by 48 h soxhlation of defatted powder by using 250 mL of methanol. The final methanolic fraction obtained was filtered through Whatman No. 1 filter paper. The filtrate obtained was concentrated under vacuum in a rotary evaporator at 40°C and stored at 4°C for further use. The dried extracts were dissolved in 98% methanol to obtain a stock solution of 10 mg/mL, which is used for application of spots on HPTLC plates.

Development of high performance thin layer chromatography fingerprinting of ursolic acid and lupeol

Thin layer chromatography (TLC) chamber: glass twin trough chamber (20 cm × 10 cm × 4 cm); CAMAG. Densitometer: TLC Scanner 3 linked to winCATS software V.4.06 (CAMAG Scientific, Inc., 515 Cornelius Harnett Drive, Wilmington, NC 28401, USA); CAMAG. HPTLC plates: 10 cm × 10 cm, 0.2 mm thickness precoated with silica gel 60 F254; E. Merck (Darmstadt, Germany). Experimental conditions: temperature, 25°C ± 2°C; relative humidity, 40%. Solvent system: toluene–ethyl acetate–formic acid (8:2:0.1). Detection wavelength: 500 nm. Visualization agent: Anisaldehyde-Sulphuric acid reagent. Slit dimension: 5.00 mm × 0.45 mm. Scanning speed: 10 mm/s and source of radiation: deuterium lamp.[17]

Method validation

The method was validated according to the ICH guidelines,[18],[19] and the statistical analysis was performed using Excel 2000 (MS Office ®).


Repeatability of the sample application and measurement of peak area were carried out using nine determinants (3 concentrations/3 replicates) covering the specified range for the procedure (200, 400, and 600 ng per band of ursolic acid) and was expressed in terms of relative standard deviation (RSD). The intra- and inter-day variation for the determination of ursolic acid and lupeol was carried out in three different concentration levels of 200, 400, and 600 ng per band. Acceptance criteria for a procedure's repeatability or intermediate precision are based on the intended use of the analytical method.

Robustness of the method

By introducing small changes in the mobile-phase composition, mobile-phase volume, duration of mobile phase saturation, and activation of prewashed TLC plates with methanol, the effects on the results were examined. Robustness of the method was done in triplicate at a concentration level of 200 ng per band of ursolic acid and the RSD and standard deviation (SD) of peak areas were calculated.

Limit of detection and limit of quantitation

To estimate the limit of detection (LOD) and limit of quantitation (LOQ), blank methanol was spotted six times and the signal-to-noise ratio was determined. LOD was considered as 3:1 and LOQ as 10:1. LOD and LOQ were experimentally verified by diluting the known concentrations of ursolic and lupeol acid until the average responses were approximately 3 or 10 times of the responses for six replicate determinations.


The preanalyzed samples were spiked with extra 50%, 100%, and 150% of the standard ursolic acid lupeol and the mixtures were reanalyzed by the proposed method. The experiment was conducted six times. This was done to check the recovery of the targeted analyte at different levels in the bark and leaves of the plant.


Ursolic acid and lupeol solutions of concentration 200 ng per band were prepared and analyzed on day 0 and after 6, 12, 24, 48, and 72 h. Data were treated for %RSD to assess the ruggedness of the method.


The specificity of the method was confirmed by analyzing the standard ursolic acid, lupeol and the extract. The band for ursolic acid and lupeol in the sample was confirmed by comparing the Rf values and spectra of the band with that of the standard. The peak purity of the ursolic acid and lupeol was assessed by comparing the spectra at three different levels, namely, peak start (S), peak apex (M), and peak end (E) positions of the band.

Calibration curve of ursolic acid and lupeol

Stock solutions of ursolic acid and lupeol (100 μg/ml) were prepared in HPLC grade methanol. Different volumes of stock solution were spotted on the TLC plate to obtain concentrations of 100-600 ng per band of ursolic acid and lupeol, respectively. The data of peak areas plotted against the corresponding concentrations were treated by least square regression analysis method validation.

Anti-microbial studies

Test micro-organisms

The various extracts of the powdered leaves of A. heterophyllus (L.) were subjected to antibacterial studies.

Following steps were involved in the study:

Step 1: Activation of microbes ( first generation) – Inactive spores (formerly maintained <4°C) were added in the nutrient broth which was incubated for 36 h. The presence of turbidity indicates the growth of culture when compared with sterile.

Step 2: Preparation of “Microbial Culture” – The microbial preserves were cultured again in nutrient broth, few ml of microbial suspension was inoculated in 20 ml of nutrient broth and all were incubated at 37°C for 36 h.

Step 3: Preparation of “Main Colony” – The 36 h grown microbial culture of each test organism was used for streaking over nutrient agar plates and subjected to incubation at 37°C for 36 h.

Step 4: Preparation of “inoculum for antimicrobial activity” – From these isolated colonies loopful of pure microbial culture was dissolved in nutrient broth (50 ml) that was incubated at 37°C for 36 h. And then, this suspension was poured to 500 ml agar nutrient media. This nutrient agar culture media served as inoculums for determination of antimicrobial activities of the extract.

Step 5: Preparation of test sample – Test samples (all methanolic extracts) were dissolved in DMSO to get stock solution of the concentration of 1000 μg/ml. From this specific concentrations of 25, 50 and 100 μg/ml were prepared of each extract. DMSO was used as control.

Step 6: Standard preparation – Ciprofloxacin and fluconazole were used as standard antibiotics to give concentration of 25, 50, and 100 μg/ml, respectively.

Step 6: Zone of inhibition by (CUP PLATE METHOD) – Wells were made in the petriplates with the main colony in agar media. All concentrations of test samples, standards and control were poured into the wells, and all the plates were incubated for 37°C for 36 h after which the zone of inhibition was calculated.

Step 7: Evaluation of minimum inhibitory concentration (MIC) with different strains.[19] Nutrient agar and test sample poured in the form of wedge, second amount of agar is poured on to the wedge, the drug is allowed to diffuse and then the petriplate is allowed to dry. Streaking of organism is done, incubated overnight.[20],[21]

Quantitative microscopy, quantitative measurement, physiochemical parameters, phytochemical screening, detection of carbohydrate content, and phenolic content

These standardization parameters were performed as per the guidelines of Ayurvedic Pharmacopoeia of India. The preliminary phytochemical investigation revealed the presence of carbohydrates, proteins, amino acid, tannins, flavonoids sterols, and terpenoids. The results of quantitative microscopy and dimensional measurements are depicted in [Table 1], [Table 2] and [Figure 6], whereas the results of phytochemical screening are shown in [Table 3]. The Physiochemical Properties of Ursolic acid and Lupeol are given in [Table 4] and [Table 5] respectively. The physiochemical analysis is presented in [Figure 7].

High-performance thin layer chromatography and validation

In this study, several solvent systems were used for the estimation of this triterpenoid and were investigated to evaluate the combinatorial separation of these compounds in a single solvent system and between different components of the extract. Among the different solvents systems investigated, a mobile phase consisting of toluene: ethyl acetate: formic acid in the ratio of 8: 2: 0.1 v/v/v demonstrated good resolution between other peaks of the extract. The procedure for the separation and determination of different compounds in methanolic fraction of A. heterophyllus leaves using HPTLC-densitometry is reported at six point calibration curves in which amount of ursolic acid and lupeol in the leaves of A. heterophyllus were found to be 0.024% and 0.025%. The Rf value for ursolic was found to be 0.68 ± 0.01 and that of lupeol was 0.46 ± 0.01. HPTLC chromatogram and densitograms were obtained from standard compounds and methanolic fractions [Figure 13], [Figure 14], [Figure 15], separation of all bands of plant samples and standard is shown in [Figure 16]. Both targeted compounds were identified by retention factor (Rf), peak purity 3D spectra and overlay ultraviolet-spectrum [Figure 17], [Figure 18], [Figure 19]. Summary of validation parameter is given in [Table 6]. Precision studies have been performed by analyzing intra- and inter-day variation for the determination of these triterpenoidal compounds which was carried out at three different concentration levels of 200, 400, and 600 ng per band; mean percentage intraday RSD values were found to be 0.54, and 0.51 for lupeol and ursolic acid, respectively, while inter-day analysis showed mean percentage RSD values of 1.47 and 1.37 for lupeol and ursolic acid, respectively, which shows good precision [Table 7]. For recovery studies, preanalyzed samples of A. heterophyllus was spiked with extra 50, 100, and 150% of the standard compounds and the mixtures were reanalyzed which shows a good recovery ranging from 97.14% to 100.05% for lupeol and 97.96%–99.20% for ursolic acid. The experimental data are expressed as mean percentages of recovered analytes, SD and RSD is also presented in [Table 8].{Figure 13}{Figure 14}{Figure 15}{Figure 16}{Figure 17}{Figure 18}{Figure 19}{Table 6}{Table 7}{Table 8}

Artocarpus hetrophyllus is one of the most common distributed plants in tropical regions of India; this plant has been part of ethnic culture since ancient time to treat several disorders and health issues, despite of high therapeutic possessions the plant is yet not much highlighted for its medicinal values factually it is highly demanded in food sectors. Pharmacognostic standardization was essential as oodles of uncertainty prevail when it comes to authentic information regarding the plant; also there was no justified pharmacognostic or anatomical work reported for the plant. Large number of phytoconstituents present in the plant gives it high medicinal value, the result from preliminary phytochemical screening as well as literature survey narrates that the plant has abundant amount of ursolic acid and lupeol thus it was thought worthwhile to subject the plant for quantitative analysis of ursolic acid and lupeol: the triterpenoids, ursolic acid, and lupeol are pronounced antihepatotoxic agent,[22] thus by detecting the presence and amount of these active constituents in leaf can pave a pathway for its utilization in several hepatic ailments, the physiochemical properties of the plant is given in [Table 5] and [Table 6] This plant somewhere lacks in the standardizing parameters that can act as a quality control tool for the better identification of the plant which is the primary step for better research of herbals. An attempt has been made to pinpoint the morpho-microscopic parameters that can be utilitarian in authentication of the plant. In this background certain reliable exemplar in TS of the leaf can be the presence of collateral open type vascular bundle that in which xylem and phloem are separated by cambium, TS of the leaf also shows that xylem and ground tissue is parenchymatous in nature while bast tissue is sclerenchymatous [Figure 1]. Cells of ground tissue contains calcium oxalate crystals whose type was very well confirmed in powder microscopy, the sui generis remarks of the leaf powder is the presence of starch grains, rosette type of calcium oxalate crystals, anomocytic stomata and sheathing trichomes [Figure 5]. HPTLC was accomplished to generate fingerprint profile of A. heterophyllus to detect and quantify the amount of ursolic acid and lupeol in leaves of the plant, the results revealed that it is present in substantial amount, both of these biomarkers has corroborated itself in fortifying the liver against several adverse conditions. Furthermore, quantitative analysis of various constituents such as gallic acid, tannic acid, rutin, and lupeol hits the antioxidant potential of the plant also the plant can be further explored for its antihepatotoxic potentials. Plant possess good antibacterial activity [Figure 20] this may be due to the presence of tannins such as gallic acid and tannic acid, the literature says that tannins have the ability to disintegrate the bacterial colony, which may be due to the interference with the bacterial cell wall.[23],[24] Data generated in this study is factual and verifiable in terms of standardization of this crude drug and also demands the attention pharmacologist to explore this plant in the field of medicine based research and development.


The author tried to bring out every necessary detail on macro-miroscopic characters of this plant. Phytochemical screening of leaf revealed the presence of several phytoconstituents such as flavonoids, tannins, terpenoids, and sterols which in itself focus that this plant can be the core of several pharmacological activities. HPTLC fingerprinting of A. heterophyllus, showed that it contains pronounced amount of ursolic acid and lupeol. Thus, this analytical result pave pathway for this plant to establish itself as an antihepatotoxic agent as speculated by author. The present study is an attempt to figure out primary needs required to generate technical or scientific standards so as to justify this herbal drug for further research work and also to keep a check on double sword (intentional and unintentional) adulteration, this study is an attempt to lay down the standards which could be used as the necessary parameters for the identification and authentication of plant A. heterophyllus. Quantification of good amount of ursolic acid and lupeol in this plant will provide extra emphasis to get explored as a potent hepatoprotective plant as both of these constituents possess hepatoprotective potential. Antimicrobial activity of the plant will help in combating the secondary infections due to liver dysfunctioning. Thus, this plant has the potential to treat several diseases along with the prevention of secondary infections caused by liver failure.
