The components were isolated from the root of Astragalus membranaceus and their structures were characterized as 3,4-methylenedioxypyrrolealdehyde, $7-O-{\beta}-D-glucopyranosyl$ 7, 3'-dihydroxy-4'-methoxy isoflavone and a naphthalene derivative on the basis of spectral and physical methods. $7-O-{\beta}-D-glucopyranosyl$ 7, 3'-dihydroxy-4'-methoxy isoflavone and the naphthalene compound showed protective effect on $CC_{l4}-induced$ cytotoxicity in primary cultured rat hepatocytes.
