| Abstract: | Objective] To determine the quercetin content in Eriocaulon buergerianum beads from different production areas,and to study the effects of two degreasing solvents on the extraction rate of quercetin.Method] Two degreasing solvents were adopted.Quercetin contents in E.buergerianum beads from different production areas were detected by high performance liquid chromatography-UV detection method.Result] As for the five production areas,quercetin contents in E.buergerianum beads after petroleum ether degreasing were 301.4,597.77,622.36,582.56,453.51 and 406.06 μg/g.Among them,E.buergerianum beads in Zhejiang Province had the maximum production,and those in Hainan Province had the minimum production.After chloroform degreasing,quercetin contents in E.buergerianum beads were 1 057.56,953.43,916.16,809.17,738.28 and 627.32 μg/g.Among them,E.buergerianum beads in Hainan Province had the maximum production,and those in Anhui Province had the minimum production.Conclusion] There were great differences in the quercetin content in E.buergerianum beads from different production areas.Chloroform degreasing had relatively high content of quercetin. |
