Abstract

Thaumatococcus daniellii is an economic plant with versatile uses in Southern Nigeria. The arils attached to the seeds contain thawnatin, a non-sugar sweetener and taste modifier. This study examined the chemical constituents of the leaf, fruit and seed ofT. daniellii. The fresh fruit, on weight basis, consists of 4.8% aril, 22.8% seed and 72.4% fleshy part The leaf contained (per 100 g): 10.67 g moisture, 8.95 gash, 17.21 g fat, 21.06 g protein, 24.61 g crude fiber 17.50 g carbohydrate, 0.10 g calcium, 0.08 g magnesium, 0.01 g iron and 0.37 g phosphorus. The fruit (fleshy part) contained 10.04 g moisture, 21.08 gash, 0.93 g fat 11.53 g protein, 18.43 g crude fiber, 37.27 g carbohydrate, 0.34 g calcium, 0.30 g magnesium, 0.01 g iron and 0.21 g phosphorus. The seed contained 15.15 g moisture, 11.30 g ash, 0.21 g fat, 10.36 g protein, 20.52 g crude fiber and 42.46 g carbohydrate. Terpenoids, flavonoids, alkaloids and cardiac glycosoides were significantly present in both the leaf and fruit whereas phlobatani:n, saponin, steroids, anthraquinones and ascorbic acid were absent. Tannin was present only in the leaf. The leaf and fruit ofT. daniellii have significant nutritional and medicinal benefits. The leaf is rich in protein and fat. The fruit is a good source of minerals, particularly, calciwn and magnesiwn; the leaf is also rich in phosphorus
