摘要:

对南方红豆杉树叶中紫杉醇的最佳醇提工艺条件进行了研究。采用乙醇浸提方法,考查了粉碎度、乙醇浓度、料液比、提取温度和提取时间对紫杉醇提取效率的影响,经过一系列的单因素试验和正交试验,得到了紫杉醇醇提工艺的最佳条件:在粉碎度120 目、95% 乙醇浸提、料液比为1∶15 、提取温度40℃ 、提取4 h 、重复2 次的条件下,经乙酸乙酯—丙酮(6∶4) 洗脱纯化, HPLC 测定紫杉醇含量,可使紫杉醇含量达到0.012 5 mg/g 。

Abstract:

The best ethanol extraction technology of paclitaxel from leaves of Taxus chinensis var. mairei was established. By a serials of single-factor experiments and L16(43)orthographic experiments, the extraction conditions were determined .The main factors contained Zerkleinerungsgrad 、ethanol concentration 、solid-liquid ratio and extraction time, the results showed that the best extraction conditions as follow :120 mesh, ethanol concentration was 95%, solid-liquid ratio was 1∶15, the extraction time was 4 hour, repeated 2 times, the leaching temperature was 40℃. Then elutioned with ethyl acetate-acetone(6∶4)through a small chromatographic column, and detected by HPLC.
Under these conditions, the total paclitaxel extraction yield can reach up to 0.012 5 mg/g(dry weight).
