Langka is a smooth tree reaching a height of 8 to 15 meters. Leaves are alternate, leathery, elliptic-oblong to obovate, entire or sometimes 3-lobed, 7 to 15 centimeters long, the apex and base both pointed. Female heads are embraced by spathaceous, deciduous, stipular sheaths, 5 to 8 centimeterslong. Sepals are two. Spike is 5 to 15 centimeters long. Fruit is green to greenish-yellow when ripe, fleshy, hanging on short stalks from the main stem or from large branches in old trees, oblong with pyramidal projections, 25 to 60 centimeters long. Seeds are numerous, oblong, 2.5 to 4 centimeters long. The testa is thin, coriaceous, surrounded by an edible luscious pulp.

• Anti-Inflammatory: Study isolated flavonoids including: 1-cycloartomunin, 2-cyclomorusin, 3- dihydrocycloartomunin, 4- dihydroisocycloartomunin, 5- cudraflavone A, 6- cyclocommunin, 7-artomunoxanthone, 8- cycloheterohyllin, 9- artonin A, 10- artonin-B, 11- artocarpanone, 12- artocarpanone A, 13, 14, 15 -heteroflavanones A, B and C. Many of the compounds exhibited varying degrees of antiinflammatory activities–inhibitory effects on chemical mediator release from mast cells, neutrophils and macrophages.
• Inhibition of Melanin Biosynthesis / Artocarpanone: Study showed the extract of AH to be one of the strongest inhibitor of tyrosinase activity. Study isolated Artocarpanone, which inhibited both mushroom tyrosinase activity and melanin production in B16 melanoma cells and presents as a potential as a remedy for hyperpigmentation in human skin.
• Inhibition of Melanin Biosynthesis / Melanoma Cells: Structure-Activity Relationship of Prenyl-Substituted Polyphenols from Artocarpus heterophyllus as Inhibitors of Melanin Biosynthesis in Cultured Melanoma Cells: Study isolated flavone-based polyphenols which were found to be active inhibitors of the in vivo melanin biosynthesis in B16 melanoma cells.
• Antibacterial: Multibeneficial natural material: Dye from heartwood of Artocarpus heterophyllus Lamk: Material isolated could be used as a direct dye for wool and silk; with antibacterial activity against B. subtilis, B. cereus, S. aureus, E coli, K pneumonia.
• Source of Provitamin A carotenoids:Analysis of carotenoids in ripe jackfruit (Artocarpus heterophyllus) kernel and study of their bioconversion in rats: Study showed jackfruit to be a good source of provitamin A carotenoids (not as good as papaya).
• Antioxidant activity / Scavenging Activity: Study showed prenylated flavonoid with more antioxidant than non-prenylated flavonoid. Study isolated prenylflavones cycloheterophyllin and artonins A and B which inhibited iron-induced lipid peroxidation and also show radical scavenging activity.
• Hypoglycemic / Anti-Diabetic: Screening of traditional antidiabetic medicinal plants of mauritius for possible -amylase inhibitory effects in vitro: Of several medicinal plants studied in Mauritius, only Artocarpus heterophyllus significantly inhibited a-amylase activity in vitro indicating that AH could act as a starch blocker to decrease post-prandial glucose peaks. Study in male Wistar rats showed the flavonoid fraction of the leaf of AH to have a higher hypoglycemic effect than the sulfonylurea drug tolbutamide with no significant effects on the liver, kidney and heart.
• Sexual Competence Inhibition: Study sought to resolve the conflicting beliefs on the roasted seeds of AH – its aphrodisiac activity vs the claim that use of the seeds prior to coitus disrupts sexual function. Study in rats utilizing a seed suspension markedly inhibited libido, sexual arousal, sexual vigor and performance while also causing mild erectile dysfunction. The results suggest that AH seeds do not have aphrodisiac activity, at least, in rats.
• Cytotoxicity / Anti-Tumor: Study showed the methanol extract to have maximum cytotoxicity on HEp2 cells with cell aggregation, cell rounding and cell death. Results suggest a potential use of the crude extract from the tegmen of AH as an antitumor agent.
• Anti-Inflammatory / Bark: Study of a methanolic extract of A. heterophyllus on a carrageenan-induced model in albino rats showed dose-dependent anti-inflammatory activity.
• Hypoglycemic / Hypolipidemic / Leaves: Study of ethyl acetate fraction of A. heterophyllus leaves in STZ-induced diabetic rats showed significant lowering of serum glucose, cholesterol and triglyceride levels. Study concludes the EA fraction contains one or more hypoglycemic and hypolipidemic principles with a potential for further development for diabetes treatment.
• Improved Glucose Tolerance / Type-2 Diabetes: Study showed the extracts of both Artocarpus heterophyllus and Asteracanthus longifolia significantly improved glucose tolerance in both normal subjects and diabetic patients.
• Hypoglycemic / Hypolipidemic / Antioxidant Pathway: Ethanol and butanol extracts showed hypoglycemic and hypolipidemic effects in STZ-diabetic rats through an oxidative pathway that may be attributed to flavonoid contents.
• Jacalin / Seed-Derived Lectin / Immunobiologic Applications: Jacalin, a major lectin protein from the jackfruit seed has been found strongly mitogenic for human CD4+ T lymphocytes. It has been found to have diverse applications: as a tool for evaluation of immune status in HIV-1, isolation of hum plasma glycoproteins, investigation of IgA -nephropathy, and detection of tumors.
• Seed Starch Binding Property: Study showed the starch obtained from A. heterophyllus fruit seeds showed comparable binding properties.
• Latex / Protease / Antimicrobial: A protease isolated and purified from crude latex of a jackfruit tree, designated as antimicrobial protease-48 kDa or AMP48 inhibited the growths of Pseudomonas aeruginosa ATCC27853 and clinical isolated Candida albicans.
• Nutritional Assessment of Jackfruit Meal/ Protease / Antimicrobial: In Sri Lanka, the jackfruit is consumed either as main meal or supplement. A nutritional assessment of a meal composed of flesh (80% available carbohydrate) and seeds (20% available carbohydrate) showed it to be a good source of starch (22%) and dietary fiber, and categorized as a low GI meal.
• Antitumor / Tegmen: Study evaluated crude extracts from the tegmen of Artocarpus heterophyllus for in vitro antitumor activity. A methanol extract yielded the maximum polyphenol content and showed maximum cytotoxicity on HEP2 cells, with cell aggregation, cell rounding, and cell death. Results suggest a potential as an antitumor agent.
• Cytotoxicity / A549 Cell Line: A methanolic extract of A. heterophyllus showed excellent cytotoxicity against A549 cell line, but had no activity against HeLa and MCF-7 cell lines. Results showed potential cytotoxicity against lung cancer, with no toxicity to normal cells (HEK293 cell line) as compared to methotrexate.
• Wound Healing: Study of a methanol leaf extract on excision would healing model showed significant wound healing activity, comparable with standard (Betadine). The period of epithelization of the extract treated group was higher than the control group.
