Abstract

Seven new acylated oleanane-type triterpene oligoglycosides, theasaponins A(4) (1), A(5) (2), C(1) (3), E(8) (4), E(9) (5), G(1) (6), and H(1) (7), were isolated from the seeds of Japanese tea plant (Camellia sinensis). The structures of 1-7 were elucidated on the basis of chemical and physicochemical evidence.
