Uses

The plant is extensively used in Indian traditional medicine. Studies on the root wood of P. serattifolia led to the isolation of acteoside, a glucoside derivative. The root bark of the plant which showed biological activities have also shown to contain a potent cytotoxic and antioxidant diterpene, 11,12,16-trihydroxy-2-oxo-5-methyl-10-demethyl-abieta-1[10],6, 8,11,13-pentene.
