A Moderat-sized tree. Leaves imparipinnate; leaflets ovate, entire, acuminate. Flowers pale pink, in axillary racemes. Pods obliquely oblong, one seeded. Occasional in marginal land.
Leaves contain furanoflavone-3'-methoxypongapin in addition to karanjin, kanjone and its two isomers 7-methoxyfurano-(4'', 5'',6,5)- flavone and 8-methoxyfurano-(4'',5''-6,7)-flavone. Bark contains a hydroxychalcone, pongapinone A, which is useful for treatment of autoimmune and inflammatory diseases. Stem bark also contain chromenoflavone, pongachromene, glabra-I, glabra-II, kuranjin, pongapin, kanugin and de-methoxykanugin. Root bark contains a large number of the flavonoid compounds, ponganones, four furoflavones, keranjin, pongapin, pinnatin and gamatin and tetra-methoxyfisetin. Flowers contain new OH-furanoflavone, pongaglabol, aurantiamide acetate, 4 known furano flavones, ß-sitosterol and kaempferol.
Seeds contain a bitter fatty oil, crystalline substances, ß-diketone, karanjin, pongamol, glabrin, pongapin, lanceolatin-B, kanjone, isopongaflavone and pongapine and also traces of essential oil. Seed oil contains di-methylchromenoflavanone, isolonchocarpin and demethoxy kanugin; oil from immature seed yields new OH-furanoflavone and pongol. Heartwood contains pongachalcone, glabrachromen, de-methoxykanugin, kanugin, pongaglabrone, ß-sitosterol and pongachromene (Asolkar et al., 1992; Rastogi & Mehrotra, 1990 & 93; Ghani, 2003).
Leaf boils into water and taken bath by this water for the treatment of itches (Marma).
