Distribution
Chemical constituents Nutrition High carbohydrate content. The young fruit is also a vegetable. The pulp (lamukot) surrounding the seeds is sweet and aromatic, rich in vitamin C, eaten fresh or cooked or preserved. The seeds are boiled or roasted. The unripe fruit can be pickled. Folkloric · Skin diseases, ulcers and wounds: Mix the burnt ashes of leaves (preferably fresh) with coconut oil, and as ointment, apply to affected areas. · Diarrhea, fever and asthma: A decoction of the root (preferably chopped into small pieces before boiling) of the tree, three to four cups daily. · Glandular swelling and snake bites: Apply the milky juice of the tree. When mixed with vinegar, it is especially beneficial for glandular swelling and abscesses, promoting absorption and suppuration. · The ripe fruit is laxative; in large quantities, it produces diarrhea. · The roasted seeds believed to have aphrodisiac properties. · In China, roasted seeds used as aphrodisiac. Root extract used for asthma , fever and diarrhea. (source) • In Mauritius, used for diabetes. • In Ayurvedic medicine, hot water extract of mature leaves used for treatment of diabetes. Others · Fruit used to flavor and age lambanog believed to increased alcohol potency. · Tree latex is used as bird lime; and heated makes a good cement for china. Studies • Antiinflammatory: Antiinflammatrory Flavonoids from Artocarpus heterophyllus and Artocarpus communis – 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–inhhibitory effects on chemical mediator release from mast cells, neutrophils and macrophages. • Inhibition of Melanin Biosynthesis: (1) Inhibitory Effect of Artocarpanone from Artocarpus heterophyllus on Melanin Biosynthesis: 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. (2) 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: Inhibitory effect of prenylated flavonoid in Euchresta japonica and Artocarpus heterophyllus on lipid peroxidation by interaction of hemoglobin and hydrogen peroxide: Study showed prenylated flavonoid with more antioxidant than non-prenylated flavonoid. • Diabetes: (1) 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.(2) Study in male Wistar rats showed the flacvonoid 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 vigour and performance while also causing mild erectile dysfunction. The results suggest that AH seeds do not have aphrodisiac activity, at least, in rats. Availability Widcrafted. Commercial fruiting. |
