Two new naphthalene and anthraquinone derivatives from Asphodelus tenuifolius.

Chromatographic separation of an ethanolic extract of rhizomes of Asphodelus tenuifolius Cav. (Asphodelaceae) yielded in addition to beta-sitosterol, stigmasterol and two anthraquinone derivatives, 1,8-dimethoxynaphthalene as well as two new naphthalene derivatives. The new compounds were identified as 2-acetyl-8-methoxy-3-methyl-1-naphthol and 2-acetyl-1,8-dimethoxy-3-methylnaphthalene. The separated compounds were identified on the basis of IR, MS, 1H and 13C NMR data.
