核桃仁种皮中类黄酮提取工艺的比较

Extraction of Flavonoids from Walnut Kernel Pellicle

该实验采用正交实验的方法对核桃仁种皮中的类黄酮进行萃取,对影响核桃仁种皮中类黄酮的提取因素提取温度、提取时间、乙醇浓度和固液比进行比较,采用分光光度计测定黄酮的含量,得出提取类黄酮的优化条件,结果显示:水浴温度为65℃,乙醇浓度为60%,提取时间为1.5h,固液比为1∶30时,提取效果最佳。

The flavonoids compounds of walnut kernel pellicle by using orehogonal design,the flavonoids were examined in the walnut kernul pellicle and the tempreture,extaction time,alcohol concentration,the solid-liquid ratio effect the extration,so we contrast the four factors.It was made use of cent light intensity of light method,and the content of flavonoids was determind from walnut kernel pellicle,the result shows that when the tempreture is 65℃,alcohol concentration is 60%,extraction time is 1.5h,the solid-liquid ratio is 1∶30 the effection is the best.
