摘要:

在单因素试验的基础上,采用L9(34)正交试验设计对长白楤木叶皂苷的提取工艺进行优化。结果表明,最佳提取工艺参数为体积分数70%的乙醇为提取剂、提取剂用量50mL、超声波提取时间30min、超声波功率200W,提取率为26.78mg/g。富集提取后的皂苷,以HPD-100树脂纯化、硅胶柱层析、制备液相进行分离,获得一个皂苷单体,经核磁共振法鉴定为楤木叶皂苷A。

Abstract:

One-factor-at-a-time method and L9(34) orthogonal array design were employed to optimize the extraction process
of saponins from Aralia contenentalis leaves. The results showed that the optimal conditions of ultrasonic extraction
were determined as follows: ethanol concentration of 70%, material-to-liquid ratio of 1:50 (g/mL), extraction duration of 30 min
and ultrasonic power of 200 W. Under the optimal extraction process, the extraction yield of saponins was up to 26.78 mg/g. Macroporous
adsorption resin HPD-100, silica gel, SephadexLH-20 and preparative HPLC were used to separate the extracted
saponin and congmuyenoside A was identified by NMR.

Key words: Aralia contenentalis, saponin, ultrasonic, extraction, identification
