Abstract

Two acylated oleanane-type triterpene oligoglycosides, chakasaponins V and VI, an aromatic glycoside, chakanoside I, and an acylated flavonol oligoglycoside, chakaflavonoside A, were isolated from the flower buds of Chinese tea plant [Camellia sinensis (L.) O. KUNTZE]. The chemical structures of those new glycosides were elucidated on the basis of chemical and physicochemical evidence.
