The topical anti-inflammatory properties of Bauhinia tarapotensis Benth. (Leguminosae) leaves have been studied by the inhibition of the croton oil-induced ear edema in mice. A bioassay-guided fractionation showed an interesting anti-inflammatory activity of the chloroform extract, that justifies the activity of the whole herbal drug. The main anti-inflammatory principles of B. tarapotensis leaves are triterpenic acids of ursane and oleanane series. The antiphlogistic activity of mixtures constituted of two ursane and oleanane isomers with different hydroxylation pattern, in the ratio 2:1, is comparable to that of indomethacin (ID50 ranging from 95 to 147 μg/cm2 and 93 μg/cm2, respectively).
