Scientific Research
Chemical constituents:
Isoflavonoids: erycristagallin, cristacarpin, orientanol B, C and F, eryvarin A–G, sigmoidin K, phaseollidin, phaseollin, isobavachin, eryvariestyrene, erystagallin A, folitenol, biseryvarin A from root; D-galactose-binding lectin from seeds
Bioactivity :
Erycristagallin and orientanol B: antibacterial stem bark extract: effective against osteophorosis, inhibits bone loss and improves the biomechanical properties of bone; D-galactose-binding lectin: agglutinate human erythrocytes; methanol extract of leaves: hypoglycaemic; methanol extract of seeds: effective in hyperlipidaemia
