| 摘 要： | 对荨麻中槲皮苷的乙醇提取工艺进行了研究。用HPLC法测定槲皮苷含量,通过L9(34)正交试验,优选了工业参数。结果表明:对提取效果影响因素依次为乙醇体积分数>料液比>浸提温度>浸提时间。最佳提取工艺条件是:体积分数70%乙醇、料液比1:30、浸提温度80℃,浸提时间3h,提取率为211mg/kg。

| Abstract: | The extraction technology of quercitr in urtica was studied with ethanol as extractor. The contained amount of quercitr was measured by HPLC.The best conditions were chosen through L9(34) orthogonal test. The results showed the first factor affecting extractor productivity was volume percentage of ethonal. The second and the third ones were rotio of feed liqued and temperature respectively. The best extraction conditions are to use 70% ethanols extractor with the ratio of feed liqued of 1:30 at the temperature of 80 ℃ for 3 h. The extraction productivity 211 mg/kg. |
