[Studies on the chemical components from leaves of Luffa cylinderica Roem]

Three compounds were isolated from the leaves of Luffa cylinderica Roem. Their structure have been identified as 21 beta-hydroxy-gypsogenin (L-2), 3-O-beta-D-glucopyranosyl-arjunolic acid (L-8) and 3-O-beta-D-glucopyranosyl-21-beta-hydroxyhederangenin (L-10), respectively, by spectroscopic (IR, 1HNMR, 13CNMR, EI-MS and FAB-MS) and chemical methods. L-2 and L-10 are new compounds.
