摘要
目的:建立舒胸片中人参皂苷Rg1、人参皂苷Rb,和三七皂苷R1含量的HPLCI]定方法。方法:采用DiamosilC18柱(4.6X250mm,5gm),流动相乙腈一水,梯度洗脱,柱温30℃,流速lmL/min,203nm波长下检测。结果:人参皂苷Rg1、人参皂苷Rb1、三七皂苷R,分别在0.442~11.050gg(r=0.9999)、0.344~8.600μg(P=0.9999)、0.208~5.200gg(r=0.9995)范围内线性关系良好,平均回收率分别为98.93%(RSD为1.7%1、98.88%(RSD为1.4%)、98.98%(RSD为1.4%)。结论:以HPLC法检测舒胸片中人参皂苷Rg1、人参皂苷Rb1和三七皂苷R1,方法简便、准确、灵敏度高、重复性好。
Objective: To develop a HPLC method for the qualification and quantification of ginsenoside Rg1, Rb, and notoginsenoside R, in Shuxiong Tablet. Methods: The column was Diamosil C18 (4.6 x 250mm, 5gm). The gradient elution mixture consisted of acetonitrile and water. The flow rate was lmL/min, and the column temperature and detection wavelength were 30℃ and 203 nm, respectively. Results: Linear ranges were 0.442 11.050 μg (1=0.9999) for ginsenoside Rg,, 0.344- 8.600 μg (r=0.9999) for ginsenoside Rb1, 0.208- 5.200 gg (r=0.9995) for notoginsenoside R,. The average recovery was 98.93% with RSD 1.7% for ginsenoside Rg1, 98.88% with RSD 1.4% for ginsenoside Rbl, 98.98% with RSD 1.4% for notoginsenoside R1. Conclusion: The established HPLC method is convenient, accurate, sensitive and repeatable.
