Cytotoxic triterpene acids from the Peruvian medicinal plant Polylepis racemosa.

Cytotoxicity-guided fractionation of the bark and stem extract of Polylepis racemosa led to the identification of ursolic acid, pomolic acid, 3-O-acetylpomolic acid, and 2-oxopomolic acid. Pomolic acid was the most cytotoxic component, and was specific for M-14 melanoma and ME180 cervical carcinoma, with GI50 values of 6.9 and 8.3 micrograms/mL respectively.[1]
