Wild jack ( Artocarpus hirsutus Lam.) is an endemic perennial tree of Western Ghats of India. Wild jack, a timber purpose tree, is distributed in several Kaan community forests. Although local people consume unripe as well as fully ripe fruits and roasted seeds, wild jack is unrecognized as a fruit tree. It remains almost undocumented with respect to nutritional value in terms of biochemical composition. We carried out biochemical profiling of ripe fruits and seeds of wild jack. Every 100 g fruit pulp was composed of 12 g total soluble sugars, 16.7 g total starch, 441 μg total carotenoids (beta carotene equivalent) and 8.1 mg ascorbic acid, 0.4 mg GAE total phenol and showed total cupric reducing antioxidant activity of 1.9 mg gallic acid equivalents (GAE). Every 100 g whole seed flour was composed of 6 g total soluble sugars, 6.6 g starch, 9.9 g total proteins, 3 mg GAE total phenol and 3.1 mg GAE total antioxidant capacity. Biochemical profiles of wild jackfruit and seeds were comparable with those of other Artocarpus fruits like jackfruit and bread fruit. Our findings suggest that wild jack deserves to be promoted as a minor fruit species of high nutritional importance and must be considered as a potential fruit crop species for further research.

野杰克（Artocarpus hirsutus Lam.）果实果肉和种子的生化成分

野杰克 ( Artocarpus hirsutus Lam.) 是印度西高止山脉的地方性多年生乔木。野杰克是一种木材用途树，分布在几个卡恩社区森林中。尽管当地人食用未成熟和完全成熟的水果和烤种子，但野生杰克并未被视为果树。它在生化成分方面的营养价值几乎没有记录。我们对野生杰克的成熟果实和种子进行了生化分析。每 100 克果肉由 12 克总可溶性糖、16.7 克总淀粉、441 微克总类胡萝卜素（β-胡萝卜素等价物）和 8.1 毫克抗坏血酸、0.4 毫克 GAE 总酚组成，并显示总铜降低 1.9 毫克五倍子的抗氧化活性酸当量 (GAE)。每 100 克全籽面粉由 6 克总可溶性糖、6.6 克淀粉、9. 9 克总蛋白质、3 毫克 GAE 总酚和 3.1 毫克 GAE 总抗氧化能力。野生菠萝蜜和种子的生化特征与菠萝蜜和面包果实等其他菠萝蜜果实的生化特征相当。我们的研究结果表明，野生杰克值得推广为具有高营养重要性的次要水果物种，必须将其视为潜在的水果作物物种以进行进一步研究。
