本文介绍了利用反相高效液相色谱测定银杏叶片提取物中总黄酮醇苷和萜类内酯含量的方法。测总黄酮醇苷以甲醇-0.4%磷酸溶液(50:50)为流动相,在360nm处检测,以槲皮素、山柰素、异鼠李素为对照品检测计算。测萜类内酯,以正丙醇-四氢呋喃-水(1:15:84)为流动相,以白果内酯、银杏内酯A、银杏内酯B、银杏内酯C为对照品,用蒸发光散射检测器检测计算。结果表明该方法线性优良且准确、稳定性好,测得的结果皆符合规定,可作为提取物制品的测定方法。

This article introduced in the use opposition highly effective liquid chromatography determination gingko leaf blade extraction total flavonol glucoside and tie the kind of lactone content method. Measures the total flavonol glucoside by the methyl alcohol - 0.4% phosphoric acid solution (50:50) for the flowing, in the 360nm place examination, by Mongolian oak Pi Su, Shan Naisu, different mouse Li Suwei compare the examination computation. Measured tie a kind of lactone, take the propanol - four hydrogen fu nan - water (1:15:84) as the flowing, take the maidenhair tree lactone, gingko lactone A, gingko lactone B, gingko lactone C as the comparison, with evaporation light scattering detector examination computation. The result indicated this method linearity fine also accurate, the stability is good, the result which obtains all conforms to the stipulation, may take the extraction product the determination method.
