Two new naphtho-α-pyrones, 8-methyltoralactone (1) and 8-methyltoralactone 10-methylether (2), were isolated from the roots of Cassia torosa CAV. along with chrysophanol, chrysophanol-10,10'-bianthrone, physcion, physcion-9-anthrone, emodin and phytosterols (a mixture of stigmasterol, campesterol, and sitosterol). The structures of the two new compounds 1 and 2 were established as 9,10-dihydroxy-7-methoxy-3,8-dimethyl-1H-naphtho [2,3-c] pyran-1-one and 9-hydroxy-7,10-dimethoxy-3,8-dimethyl-1H-naphtho [2,3-c] pyran-1-one, respectively, on the basis of spectral and chemical evidence.
