A new oleanane triterpene from the leaves of Ficus hirta

Repeated column chromatography of the n-hexane extract of Ficus hirta leaves (Moraceae) led to isolation of a new oleanane triterpene, 3β-hydroxy-11-oxo-olean-12-enyl-3-stearate (1) in addition to three known compounds, taraxerol (2), 3β-acetoxy-11α-methoxy-12-ursene (3) and 3β-acetoxy-11α-hydroxy-12-ursene (4). Their structures were elucidated by spectroscopic methods and by comparison with data reported in the literatures.
