- 論文の詳細を見る
Two new dimeric tetrahydroanthracene derivatives, torosaols I (1) and II (2), were isolated from the fresh roots of Cassia torosa Cav. along with pinselin, questin, 7-methyltorosachrysone, singueanol-I, germichrysone, germitorosone, methylgermitorosone, and phlegmacins A_2 and B_2. The structures of compounds 1 and 2 were established as 3,3', 4,4'-tetrahydro-2,3,3', 8,8', 9,9'-heptahydroxy-6,6'-dimethoxy-3,3', 7,7'-tetramethyl-10,10'-bi-1(2H)-anthracenone and 5-[3', 4'-dihydro-3', 8', 9'-trihydroxy-6'-methoxy-3', 7'-dimethyl-1' (2'H)-anthracenon-10'-yl]-3,4-dihydro-9,10-dihydroxy-3-hydroxymethyl-7-methoxy-3,8-dimethyl-1H-naphtho[2,3-c]pyran-1-one, respectively, on the basis of spectral evidence.
