摘要
用高效液相色谱法测定银杏叶及提取物中银杏内酯A、B、C和白果内酯的含量。采用C18分离柱,示差检测器,甲醇:水(33:67)为流动相,方法回收率平均达97%以上,变异系数(CV)为2.1%。
A HPLC method had been developed for the determination of Ginkgolide A. B. C andBilobalides in Ginkgo biloba levaves and it's extract. A C18column using methanol, water (33: 67) asmobile phase, and RI detector was used. The results have shown that the-recoveries are over 97%and CV is 2. l%.
