【摘要】 在单因素试验的基础上,以提取时间、提取温度以及料液比为因素,以桃叶珊瑚甙提取率为指标,用正交试验法对杜仲叶中桃叶珊瑚甙的提取工艺进行了优化研究。结果表明,提取温度和提取时间对提取效果有显著影响,影响提取效果的主次顺序为温度>时间>料液比。最佳提取参数为:温度80℃,时间1h,料液比1∶8。更多还原

【Abstract】 On the basis of single factor experiment,the optimum technology extracting aucubin from Eucommia leaves was studied by orthogonal test.An orthogonal test table L₉（3⁴） was used with the factors of extracting temperature,time and the ratio of leaf to liquid.The extracting rate of aucubin was the indication in orthogonal test.The optimum technological condition was temperature 80 ℃,time 1 h,stock ratio （1∶8）.And temperature and time had notable influence on the extracting results.更多还原
