| 摘 要： | 目的建立肉苁蓉中苯乙醇苷的含量测定方法。方法选用测定波长333nm,以松果菊苷为对照品,采用大孔树脂-紫外分光光度法对肉苁蓉中苯乙醇苷的含量进行了测定。结果松果菊苷在8～40mg·mL-1范围内具有良好的线性关系,回归方程为Y=2.3010X-0.0041(r=0.9991),平均回收率为99.1%,RSD为0.4%。结论该方法操作简便,结果准确,重复性好,可用于肉苁蓉的质量控制。

| Abstract: | Objective To establish a quantitative method for the determination of total phenylethanoid glycosides in Cistanche desertiola.Method Using detection wavelength at 333nm and echinacoside as standard,macroporous resin-UV spectrophotomatry was developed to determine total phenylethanoid glycosides in Cistanche desertiola.ResultsThe calibration curve was in good linea-rity over the range of 8~40 mg·L-1 with the regression equation Y=2.301 0X-0.004 1(r=0.999 1).The average recovery was 99.1% with RSD=0.4%.Conclusion The method is simple,accurate and reproducible.It can be used to control the quality of Cistanche desertiola. |
