• 論文の詳細を見る

• The structure of theasapogenol B, one of seeds sapogenols of Thea sinensis L. (Theaceae) has been established as 3β, 16α, 21β, 22α, 28-pentahydroxy-olean-12-ene (II). Based on the identity of theasapogenol B with barringtogenol C, a sapogenol of Barringtonia acutangula GAERTN. (Lecythidaceae) and its structure by the previous workers being (I), the structure of barringtogenol C has been revised to II incidentally along with the revision of the structure of barringtogenol D from (2) to XVI. In addition, the designations of seeds sapogenols of Thea sinensis L. have been proposed to be theasapogenol A (I), barringtogenol C (II), camelliagenin C (III), dihydropriverogenin A (IV), and theasapogenol E (V) respectively.
