- 論文の詳細を見る
The saponin fraction from the seeds of the tea plant, Camellia sinensis L. var. assamica PIERRE cultivated in Sri Lanka, was found to show a potent protective effect on gastric mucosal lesions induced by ethanol in rats. Nine new acylated polyhydroxyoleanene-type triterpene oligoglycosides called assamsaponins A-I were isolated from the active saponin fraction together with three known saponins, theasaponin E_1 and E_2 and camellias-aponin B_1. The structures of assamsaponins A-E were elucidated on the basis of chemical and physicochemical evidence. Theasaponin E_1 exhibited potent gastroprotective activity.
