【摘要】 目的:研究射干中鸢尾苷的提取工艺。方法:采用正交试验法进行优选,紫外分光光度法测定鸢尾苷含量。结果:乙醇用量、提取时间和乙醇浓度对提取有显著性影响。结论:最佳提取工艺为70%乙醇:射干(ml/g)=6:1,每次提取120min。更多还原

【Abstract】 Objective: To study the extraction process of Tectoridin (an active component) from Rhizoma Belamcandae. Methods: The optimum extraction process was selected with the orthogonal design .The content of Tectoridin was determined by UV-spectrophotometry. Results: The extraction time, alcohol amount and concentration have significant effects on the extraction of Tectoridin. Conclusion: The 0ptimum Extraction Process is as follows: the ratio of 70% alcohol (ml) to Rhizoma Belamcandae(g) is 6/1, and extracting for 120 min each time.更多还原
