摘要
目的:研究天麻药材的提取和精制工艺。方法:以天麻药材指标性成分天麻素的转移率为指标,采用正交试验设计和单因素考察相结合的方法对天麻药材的提取、精制工艺进行优化。结果:天麻药材以水为溶媒,采用加热回流的提取方法;采用碱性醇沉法、水沉降法进行精制。结论:天麻素的提取转移率为84.85%;所选用的精制方法可有效去除蛋白质、草酸盐、树脂、鞣质等杂质。
Objective:To study extraction technique and purification technique of Rhizome Gastrodiae. Methods:Orthog- onal experiment design and single factor tests were used in optimizing the extraction and purification technology of Rhizome Gastrodiae by measuring transition probability. Results:Rhizoma Gastrodiae was reflux- extracted with water, and purified with the methods of basic - ethanol deposition and water deposition. Conclusion: Transference rate of Rhizome Gastrodiae could arrive at 84.85%, and the impurities such as protein, oxalate, tannin and resin were all removed.
