范文编号:SW049 范文字数:8522,页数:28 摘 要:优选淫羊藿中淫羊藿苷的提取工艺。方法:以淫羊藿苷含量为检测指标,根据提取时间、提取次数、温度、乙醇浓度4个影响因素,采用L9(34)正交法试验。紫外分光光度计测定淫羊藿苷含量。结果:影响提取因素提取次数、提取温度、料液比、乙醇浓度。结论:乙醇浓度40%、料液比180ml、温度90℃、提取次数4次效果最好。抗氧化结果:在0.6ml时达到最大清除率83%。抗氧化能力在6.5ml时达到最大吸光度0.8A。 关键词:淫羊藿苷;淫羊藿;提取工艺;正交试验;抗氧化。 Epimedium bioactive substances from the research and anti-oxidation Abstract: Epimedium optimization of icariin in the extraction process. Method: icariin in indicators for the detection, according to extracts of time, the number of extraction, temperature, alcohol concentration four factors used L9 (34) Orthogonal test. Ultraviolet spectrometer of icariin content. Results: The impact of extraction from the number of factors, from temperature, liquid ratio, alcohol concentration. Conclusion: The concentration of 40 percent ethanol, feed than 180 ml, temperature of 90 ℃, from the number four best effect. Antioxidant results:0.6 ml at the maximum 83 per cent clearance rate. In 6.5 ml, 0.8A maximum absorbance. Keywords:Icariin; Epimedium; Extraction Process; Orthogonal;Antioxidant. 目 录
