摘要:

目的:确定空心莲子草皂苷最佳提取工艺。方法:采用微波辅助法提取空心莲子草中的皂苷类化合物,通过正交试验确定最佳提取工艺;以齐墩果酸为对照,采用分光光度法在570nm 波长处测定其中的皂苷,回归方程为:Y =1.904C + 0.0054,r = 0.9990。结果:最佳工艺条件为20% 的甲醇、固液比1:20(g/mL)、微波时间20s、微波功率640W、间歇提取4 次。结论:选出了空心莲子草皂苷的最佳提取工艺,用齐墩果酸做标准品,采用分光光度法测定皂苷含量,操作简便,结果准确。

Abstract:

Objective: The development of an optimal process for the microwave-assisted extraction of saponins from the whole plant of Alteman theraphiloxeroides (Mart.) Griseb (APG) in presented in this paper. Methods: Microwave was used for the extraction of saponins with aqueous methanol solution as an assistant approach, and process optimization was achieved by single factor and orthogonal array design experiments. The quantitative analysis of saponins was performed using oleanolic acid as a reference substance, which showed maximum adsorption at 570 nm wavelength, with a calibration equation of Y = 1.904C +0.0054 (r = 0.9990). Results: The optimum process conditions for the extraction of saponins were 20 s microwave treatment at 640 W power for intermittently extracting with a 20-fold volume of 20% aqueous solution for 4 times. Conclusion: The developed extraction process is easy to operate and reliable.

Key words: Alteman theraphiloxeroides (Mart.) Griseb (APG), saponin, microwave-assisted extraction
