Abstract
A new glucuronide saponin (1) was isolated as its methyl ester (2) from the leaves of Camellia sinensis var. sinensis. On the basis of its spectral data and the results of chemical degradation, the structure was elucidated to be 3-O-[beta-D-galactopyranosyl(1-->2)-[beta-D- xylopyranosyl(1-->2)-alpha-L-arabinopyranosyl(1-->3)]- beta-D-glucuronopyranosyl]-21-O-cinnamoyl-16,22-di-O-acetylbarr ingtogenol C.Entities:
