Abstract

Seven new acylated oleanane-type triterpene oligoglycosides, theasaponins A₄ (1), A₅ (2), C₁ (3), E₈ (4), E₉ (5), G₁ (6), and H₁ (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.
