The isolation of friedelin, putranjivadione (I), friedelanol and a new trieterpenoid Roxburgholone, C30H50O2, from the bark of P. roxburghii has been described. Roxburgholone has been shown to be 3α-hydroxyfriedelan-7-one (II). The hydroxyketone obtained by sodium borohydride reduction of putranjivadione (1) has been shown to be 3β-hydroxyfriedelan-7-one (XIII).
