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,2'H)-dione, and singueanol-II (8) or 6,6'-dimethoxy-3,3',8,8',9,9'-hexahydroxy-3,3',7,7'-tetramethyl-3,3',4,4'-tetrahydro(5,10'-bianthracen)-1,1'(2H,2'H)-dione.
