目的：建立银杏内酯滴丸中银杏内酯A、银杏内酯B含量测定方法。方法：采用高效液相色谱法，以正丙醇-四氢呋喃-水（1∶27∶72）为流动相，流速：1.0 mL·min-1，检测波长：220 nm。结果：建立了银杏内酯滴丸中银杏内酯A、银杏内酯B含量测定方法，且银杏内酯A、银杏内酯B的RSD分别为1.39%，2.16%。结论：本方法简便可靠，可用于银杏内酯滴丸的质量控制。

This study was aimed to establish the method of determining ginkgolide A and ginkgolide B content in ginkgolide dropping pills. High performance liquid chromatography (HPLC) was used in the research with N-propanol-THF-water (1∶27∶72) as the mobile phase. The flow rate was 1 mL·min-1. And the detection wavelength was at 220 nm. The results showed that the determination method of ginkgolide A and ginkgolide B content in ginkgolide dropping pills was established. And the RSD of ginkgolide A and ginkgolide B were 1.39% and 2.16%, respectively. It was concluded that this method is simple and reliable, which can be used for quality control of ginkgolides dropping pills.
