==Chemical Composition==
Ethanol extraction of the fresh leaves of P. roxburghii proved convenient for the isolation of polyphenolic compounds. In addition to triterpenoids this extract yielded ellagic acid, gallic acid, gallocatechin, ellagi-and gallo-tannins and saponins. The main components of the root bark were triterpenoids, friedelin, putranjivadione, roxburgholone, methyl putrate and saponins derived from oleanolic acid.
