A New Triterpenoid Saponin from Camellia oleifera Fruit Hull

A new triterpene saponin (1), along with oleanolic acid 3-O-β-D-glucopyranoside (2), were isolated from the fruit shells of Camellia oleifera Abel. The structure of 1 was determined to be 3-O-β-Dglucopyranosyl( 1"→6')α-L-rhamnosyl 27-hydroxyoleanolic acid-28-O-β-D-glucopyranoside, which was established by analyses of their 1H and 13C NMR spectra with the aid of 2D experiments.
