This study was carried out to identify and quantify the flavonoids from 6 different plant parts of Allium victorialis var. platyphyllum (AVP), including the flower, leaf, root, stem, flower stalk, and flower seed, using liquid chromatography/ mass spectrometry. Two major flavonoids were structurally identified as quercetin (3,5,7,3’4,’-pentahydroxyflavone) and kaempferol (3,5,7,4’-tetrahydroxyflavone) at contents of 11.8-25.8 and 6.0-64.4 μg/mL, respectively. In particular, the flower and root plant parts contained the highest amounts of quercetin and kaempferol compared to the other parts. We also assessed the recovery effects of each plant-part extract of AVP on gap junctional intercellular communication (GJIC) in WB-F344 cells by the scrape-loading and dye transfer (SL/DT) method. According to the results, GJIC was reduced by approximately 70.2% (62.3±12.5 cells) compared to the control (209±9.5 cells, 100%) when 12-O-tetradecanoylphorbol-13-acetate (TPA) was treated alone in the WB-F344 rat liver epithelial cells. However, the stem extract (0.2 mg/mL) restored GJIC to basal levels (92%, 204±2.3 cells, p<0.01) and the flower extract (0.2 mg/mL) stimulated GJIC to 82.5% (172.6±8.3 cells, p<0.05), when applied together with the TPA.
