摘要
The determination method of 10-hydroxycamptothecin in Camptotheca acuminata fruits by high-performance liquid chromatogram (HPLC) was studied. The HPLC analysis was performed on a HIQ sil C18(4.6×250 mm) column with mobile phase of acetonitrilewater (3:7, V:V), flow rate 1 mLmin-1 and UV detective wavelength 266 nm. Extracting 10-hydroxycamptothecin by ultrasonic method from fruits of C. acuminata to prepare samples for analysis was systematically discussed. The optimal extraction condition was carried out by 60% alcohol solution at 60℃ for 50 minutes.
以高效液相色谱法作为羟基喜树碱含量检测方法,系统讨论了用超声法从喜树果实中提取羟基喜树碱用以制备分析样品的方法。采用HIQ sil C18柱(4.6×250 mm),流动相为乙腈:水(3:7,V:V),流速1 mL/min,检测波长266 nm。确定的最佳超声提取条件为:以60%乙醇为提取溶剂在60℃提取50 min。图3表1参10。
