摘要
目的 :以仙茅苷、仙茅多糖为定量指标 ,研究仙茅的提取工艺。方法 :采用正交试验法进行优选 ,高效液相色谱法测定仙茅苷含量 ,分光光度法测定多糖含量。结果 :提取次数对仙茅苷和仙茅多糖有显著性和非常显著性差异 ,溶媒用量对仙茅多糖的提取有较大影响。结论 :最佳提取工艺为药材 8倍量水煎煮 ,每次 90min ,提取
Objective:To study the extraction for the curculigoside and polysaccharide of Rhizoma Curculiginis. Methods: The optimum extraction was selected by the orthogonal design. The content of total curculigoside was determined by HPLC, The content of polysaccharide of Rhizoma Curculiginis was determined by spetrophotometry.Results: The extraction times affected significantly total curculigoside and Polysaccharide of Rhizoma Curculiginis. Conclusion: The optimum extraction is as follows: adding 8 times amount of water into Chinese medical materials, and boiling for 90 min each time, extracting three times in all.
