摘要:

采用pH区带精制逆流色谱法从广西地不容中制备青风藤碱,溶剂系统为石油醚乙酸乙酯甲醇水(3:7:1:9,V/V),上相加10 mmol/L三乙胺为固定相,下相加10 mmol/L盐酸为流动相。一次进样1.0 g,可得纯度为99.5%的青风藤碱600 mg,所得产物经ESI-MS,1H NMR和13C NMR进行结构鉴定。本方法效率高,制品纯度高,适合青风藤碱的大量制备。

Abstract:

      We employed pH-zone refining counter-current chromatography to prepare high-purity sinoacutine from Stephania kwangsiensis. Its solvent system was composed of petroleum ether-ethyl acetate-methanol water (3:7:1:9, V/V), in which triethylamine (10 mmol/L) was added to the upper organic stationary phase as a retainer and hydrochloric acid (10 mmol/L) was added to the aqueous mobile phase as an eluter. The structure of sinoautine was identified by ESI-MS,1H NMR and 13C NMR. The purity of sinoacutine determined by RP-HPLC was 99.5%. This approach has such advantages as high-efficiency and high-purity, suitable for the preparation of large amount of sinoacutine.

Key words: Stephania kwangsiensis, Sinoacutine, pH-zone-refining counter-current chromatography
