目的:完善倍生颗粒的质量标准。方法:应用紫外分光光度法在检测波长为599nm处对选择的有效成分(人参皂苷Re)进行含量测定。结果:利用紫外分光光度法对该颗粒中所含人参皂苷Re为1g样品中含0.368mg,在0.015～0.04mg/mL内线性关系良好,R=0.9979,平均回收率为99.63%,RSD=1.05%(n=6)。结论:用紫外分光光度法测定该颗粒剂中人参皂苷Re的含量,方法准确,重现性好,可作为倍生颗粒的含量测定方法。
Objective: To improve the quality standards of times particles. Methods: The active ingredient (ginsenoside Re) was determined by ultraviolet spectrophotometry at the detection wavelength of 599 nm. Results: The content of ginsenoside Re contained in 1g sample was 0.368mg by UV spectrophotometry, the linearity was within 0.015 ~ 0.04mg / mL, R = 0.9979, the average recovery was 99.63%, RSD was 1.05 % (n = 6). CONCLUSION: The content of ginsenoside Re in this granule is determined by UV spectrophotometry. The method is accurate and reproducible. It can be used as a method to determine the content of ginseng granules.
