从日本茶树Camellia smensis种子的皂苷级分中分离出三种新的酰化齐墩果烷型三萜皂苷，即茶皂苷A（6）（1）、A（7）（2）和B-5（3），以及已知的成分foliatheasaponin III（4）。糖苷1-3的结构被阐明的基础上，光谱，化学和物理化学证据。
Three new acylated oleanane-type triterpene saponins, theasaponins A(6) (1), A(7) (2), and B-5 (3), were isolated from the saponin fraction of the seeds of the Japanese tea plant Camellia smensis together with the known constituent foliatheasaponin III (4). The structures of the glycosides 1-3 were elucidated on the basis of spectroscopic, chemical, and physico-chemical evidence.
