Three saponins, isotheasaponins B1-B3, were isolated from the leaves of the tea plant Camellia sinensis var. sinensis, and their structures were determined to be theasapogenol B [beta-D-galactopyranosyl(1-->2)][beta-D-xylopyranosyl(1-->2)-alpha-L-arabinopyranosyl(1-->3)]-beta-D-gulcopyranosiduronic acid with two acyl groups by spectroscopic analysis.
从茶树中华变种的叶子中分离出三种皂苷，即异茶皂苷B1 - B3，通过光谱分析确定它们的结构为茶皂醇B [β-D-吡喃半乳糖基(1→2)][β-D-吡喃木糖基(1→2)-α-L-阿拉伯吡喃糖基(1→3)]-β-D-古洛糖醛酸苷，带有两个酰基。
