概要
- 論文の詳細を見る
The methanolic extract from the flower buds of Chinese tea plant (Camellia sinensis (L.) O. KUNTZE) was found to inhibit release of β-hexosaminidase from RBL-2H3 cells. From the methanolic extract, six new acylated oleanane-type triterpene Oligoglycosides, floratheasaponins D-I, were isolated together with 21 known compounds including floratheasaponins A-C. The chemical structures of floratheasaponins D-I were elucidated on the basis of chemical and physicochemical evidence. The principal constituents, floratheasaponins A-F, were found to show the inhibitory activity on the release of β-hexosaminidase from RBL-2H3 cells.
