Four tetrahydroanthracene derivatives with antimicrobial and antispasmodic activities have been isolated from Cassia singueana. The evidence described in the following indicates them to be torosachrysone (1), germichrysone (4), and two new dimeric tetrahydroanthracenes, singueanol-I (7) or 6,6′-dimethoxy-3, 3′,8,8′,9,9′-hexahydroxy-3,3′,7,7′-tetramethyl-3,3′,4,4′-tetrahydro(10,10′-bianthracen)-1,1′(2H
从决明子中分离到四种具有抗菌和解痉活性的四氢蒽衍生物。以下描述的证据表明它们分别是:甲苯磺啶酮(1),细菌丹参酮(4)和两个新的二聚四氢蒽,singueanol- I(7)或6,6' -dimethoxy-3,3',8,8', 9,9'-六羟基-3,3',7,7'-四甲基-3,3',4,4'-四氢(10,10'-双蒽)-1,1'(2H,2'H) -二酮和singueanol-II(8)或6,6'-二甲氧基-3,3',8,8',9,9'-六羟基-3,3',7,7'-四甲基-3,3 ',4,4'-四氢(5,10'-联蒽)-1'(2H,2'H)-二酮。
