黄芪皂甙提取工艺的研究

Research on Extraction Technology Optimization of Radix Astragloside

用索氏提取法、微波提取法和超声波提取法3种方法对黄芪皂甙的提取进行了实验研究,结果表明,用微波法提取,加10倍量70%的乙醇,提取40min为最佳提取方法。考察了提取溶剂乙醇的浓度、用量及提取时间等对黄芪皂甙提取的影响,使用分光光度法测定提取物中黄芪皂甙的含量。

This paper does the experiment on Radix Astragalosi extraction method,such as sorbite extraction method,microwave extraction method,ultrasonic wave extraction method.The result demonstrates microwave method is the best method,which adds 10 times 70% alcohol to extract 40 minutes.The experiment also studies extraction dissolvent on effect of Astragaloside from alcohol concentration, quantity, extraction time,etc.The experiment uses spectrophotometric titration to determine the content of Astragaloside from extraction.
