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.关键词
