Chemical constituents:
Bark and seeds contain significant amounts of saponins including an anti-tumour saponin, entanin, which on hydrolysis yields entagenic acid. Seeds also contain a fixed oil, proteins, albumins and globulins, essential amino acids, fatty acids such as oleic and linoleic acids; phaseoloidin, tyrosine glucoside and dopamine glucoside and many minerals. A new triterpenoid, entagenic acid and a crystalline sapogenin have also been isolated from the seeds.

Myristic, palmitic, stearic, arachidic, behenic, and linolenic acids have been obtained from seed oil hydrolysate. Seed oil also contains triglycerides comprised of monounsaturated diolein and dilinolein, saturated oleolinolein, dioleolinolein, trioleein, oleodilinolein and trilinolein. Pericarp contains β-sitosterol, α-amyrin, quercetin, cyanidin chloride and gallic acid. Kernel contains oleanolic and echinocytic acids and methyl mercaptan (Ghani, 2003, Rastogi & Mehrotra, 1993).
