Abstract:

Bioassay-guided fractionation of an EtOAc extract of the leaves of Rosa laevigata afforded two new 19-oxo-18,19-seco-ursane-type triterpenes (1 and 3), a new ursane-type nortriterpene (2), a new ursane-type triterpene lactone saponin (4), and two new oleanane-type triterpenoids (5 and 6), together with eight known triterpenoids (7-14). Compound 1, a 19-oxo-18,19-seco-28-norursane, possesses a conjugated diene between C-12 and C-17. Several of the isolated compounds (1, 5, 7, 11, and 13) exhibited moderate activities in anti-inflammatory assays in vitro.
