摘　　要： [目的]测定不同产地谷精珠中槲皮素的含量,考察2种脱脂溶剂对谷精珠中槲皮素提取率的影响。[方法]采用2种溶剂脱脂处理,并用高效液相色谱-四通道紫外检测法测定不同产地谷精珠中槲皮素的含量。[结果]在5个产地中,石油醚脱脂后的谷精珠中槲皮素的含量分别为:301.4、597.77、622.36、582.56、453.51和406.06μg/g;其中,以浙江产的含量最高,海南产的最低。氯仿脱脂后的谷精珠中槲皮素的含量分别为:1 057.56、953.43、916.16、809.17、738.28和627.32μg/g;其中,以海南产的含量最高,安徽产的最低。[结论]不同产地谷精珠中槲皮素含量差异较大;氯仿脱脂效果好,提取液中槲皮素的含量较高。 [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.
