摘要
以红景天为原料,以水为溶剂研究微波提取红景天苷的最佳工艺参数。通过试验,分别考察了固液比、微波功率、微波处理时间、提取次数等因素对提取效果的影响,探讨了微波提取的机理。在红景天苷初提液的澄清处理中选择有机絮凝剂、无机絮凝剂和高速离心技术相结合的方法,其澄清效果明显优于单一絮凝剂。
The optimized technological parameters for extracting salidroside from rhodiola with microwave irradiation and water as solvent were studied.The key factors,including the ratio of solidto liquid,microwave power,microwave irradiation time and times of extraction,were studied for the extraction yield.The mechanism of extraction of microwave was discussed.The methods of organic flocculation,inorganic flocculation and highspeed centrifugate were applied to clarify the extract.The clarifying effect of this method is far higher than that of single flocculation method.
