摘要: 建立酸枣仁中欧鼠李叶碱(酸枣仁碱A)的高效液相色谱-三重四极杆质谱分析方法,在此基础上,以酸枣仁为原料,以欧鼠李叶碱的提取率为考察指标,通过单因素试验和正交试验对酸枣仁中欧鼠李叶碱回流提取过程中的提取溶剂、提取溶剂中的酸、提取温度、酸浓度、液固比和提取时间进行优化,确定了乙醇为理想提取溶剂,提取溶剂中添加乙酸,最优回流提取工艺条件为:提取温度60 ℃,液固比20:1 (V∶g),乙酸浓度8%,提取时间4 h。最优提取工艺条件下欧鼠李叶碱的提取率为32.286 μg/g。

Abstract: A sensitive high performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) method was developed for the determination of frangufoline (sanjoinine A) from Semen Zizyphi Spinosae.The reflux extraction conditions (extraction solvent,the acid in extraction solvent,extraction temperature,acid concentration,liquid-solid ratio,extraction time) of frangufoline from Semen Zizyphi Spinosae were investigated by single factor tests and orthogonal experiment with the extraction rate of frangufoline as the index.The results showed that the optimal extraction solvent was ethanol and the optimal acid was acetic acid.The optimal extraction conditions were as follows:extraction temperature 60 ℃,liquid-solid ratio 20∶1 (V∶g),acetic acid concentration 8%,extraction time 4 h.Under the optimal extraction conditions,the extraction rate of frangufoline was 32.286 μg/g.
