- Abstract: OBJECTIVE: To study flavonoids from the leaves of Zelkova serrata. METHODS: The leaves were extracted with 70% ethanol by continuous thermal reflux. The extract was separated and purified by silica gel column chromatography, polyamide column chromatography, preparative TLC and other isolation techniques. Their structures were identified by their physical properties and spectroscopic data. RESULTS: Eight flavonoids were isolated and identified as myricetin (1), dihydromyricetin (2), quercetin (3), myricitrin(4), myricetin-3-O-β-D-xyloside(5), quercetin-3-O-β-D-xyloside(6), quercitrin(7), and rutin(8). CONCLUSION: All compounds were isolated from Schneider Zelkova leaves for the first time.
