建立了银杏外种皮中银杏酚酸超临界CO2萃取高效液相色谱的分析方法,使用C18液相色谱柱,以甲醇:水(85:15,V/V)为流动相,在UV310 nm下对其进行了定性定量分析,方法的线性相关系数r=0.99993。加标回收率≥97.5%,RSD小于2%,该方法已用于银杏外种皮中银杏酚酸的萃取检测。 A method was developed for the determination of ginkgolic acids in Ginkgo biloba bark by supercritical CO2 extraction. The C18 column was used with methanol: water (85:15, V / V) as the mobile phase at UV310 nm Qualitative and quantitative analysis of the method, the method of linear correlation coefficient r = 0.99993. The spiked recoveries were more than 97.5% and the RSD was less than 2%. This method has been applied to the extraction of ginkgolic acids in the ginkgo exocarp.
