title: [Studies on the chemical structure of lucyoside R from leaves of Luffa cylindrica roem].
abstract: A new pentacyclic triterpenoid saponin, lucyoside R, has been isolated from the leaves of Luffa cylindrica along with lucyoside G. Its stucture was established as 2 alpha, 21 beta-dihydroxyhederagenin-3-O-beta-D-glucopyranoside based on spectral and chemical evidence.
