A new triterpenoid from the leaves of Ficus benjamina (var. comosa).

The benzene extract of the leaves of Ficus benjamina (variety comosa) afforded a new triterpene, named serrat-3-one (Fc-2), along with the known phytoconstituents pentacontanyl decanoate (Fc-1), friedelin and beta-sitosterol. Their structures were established on the basis of chemical and physical evidence (IR, (1)H NMR, (13)C NMR and MS). The aqueous and alcoholic extracts of leaves of F. bejamina showed significant antinociceptive activity in an analgesiometer test.
