| Abstract: | AIM To study the chemical constituents from Allium cepa L.var.agrogatum Don.and their antifungal activity.METHODS The 95%ethanol extract of A.cepa was isolated and purified by MCI,Sephadex LH-20,C 18 and semi-preparative HPLC,then the structures of obtained compounds were identified by physicochemical properties and spectral data.Their antifungal activity against pathogen of tomato Fusarium wilt was evaluated by microdilution technique.RESULTS Four compounds were isolated and identified as quercetin(1),quercetin-4′-O-β-D-glucoside(2),diasyringaresinol(3),tryptophan(4).Compounds 1-2 could inhibit the growth of pathogen of tomato Fusarium wilt,with the MIC values of 25.0,12.5μg/mL,respectively.CONCLUSION Compound 3 is isolated from this plant for the first time.Compounds 1-2 have good antifungal activity. |
