Allium victorials var. platyphyllum were ground, extracted with 95% EtOH, concentrated, and fractionated with a series of n-hexane, methylene chloride, ethyl acetate, butanol and water on a separatory funnel. A portion of ethyl acetate soluble fraction was chromatographed on a Sephadex LH-20 and silica gel column using various solvent system as eluents. The isolated compounds were identified by TLC, $^1H-$, $^{13}C$-NMR, HMBC and EI-MS. Astragalin (compound 1), kaempferol (compound 2), quercetin (compound 3), ferulic acid (compound 4) were isolated from the ethyl acetate soluble fraction of A. victorials.
