Five compounds were isolated from the whole plant of Arabis glabra (Cruciferae) through repeated silica gel and Sephadex LH-20 column chromatography. Their chemical structure were elucidated as salicylic acid, 2,5-dihydroxybenzoic acid, astragalin, rutin, and $quercetin-3,7-O-{eta}-D-diglucopyranoside$ by spectroscopic analysis.
