Chemical Composition

Pithecellobium dulce is a species of flowering plant in the pea family Fabaveae, that is native to the Pacific Coast and adjacent highlands of Maxico, Central Amerca, and northern South America. Pithecellobium dulce. It is used as medicinal plant. An extract of the leaves is used for gall ailments and to prevent miscarriage. The methanolic extract of leaves was obtained by Soxhelt extractor followed by concentration in rotary evaporator. Separation of bioactive chemicals was carried out by column chromatography while studies by GC-MS which shows presence of following bioactive chemicals Phytol, Anthracene, 9(3butenyl), mm Diisooctyl phthalate, 13Docosenamide,, 3,6,9triethyl3,6,9trimethyl Formic acid, Cyclotetrasiloxane, octamethyl, l(+) Ascorbic acid 2,6dihexadecanoate. The leaf extract of Pithecellobium dulce showed good inhibition against gram positive Organisms. The highest inhibition was noted S.epidermidis (24mm), P. acne(14mm) and s. aur(11mm).

Chemical, fatty acid, amino acid composition and antioxidant activity of dehydrated Momordica tuberosa Roxb. (Adavi Kakara ) was investigated. The dehydrated M. tuberosa  possessed 21.76% protein and 33.96% fibre. The total lipid of seed was rich in oleic (22.05%), linoleic (25.09%) and linolenic (6.17%) acids. Major amino acids of the seeds are glutamic acid, arginine, leucine, aspartic acid and alanine. The ratio of essential to nonessential amino acids was 0.57 and in which, essential amino acids contributed to an extent of  36.36 g/100 g seed proteins. Inhibition of 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radical at 50% was higher with pulp (6 mg) than whole fruit (14 mg) and seeds (20 mg). The ABTS radical inhibition assay was found to be high in whole fruit (98.4%) and followed by pulp (50.76%) and seed (16.14%) at 2 mg. Marginal differences in ferric ion reducing power were observed in all the samples at 10 mg level.
