- 摘要:
- 以银杏的种皮为试验材料,进行银杏酸提取工艺研究,并通过L9(34)正交实验探讨了料液比、提取溶剂浓度、时间、温度对提取效果的影响。结果表明:影响银杏酸提取效果的最主要因素是温度,并得出银杏酸提取的最佳工艺条件为:料液比1∶40、甲醇浓度90%、时间2.5 h、温度60℃,在此条件下分别在242、310 nm检测,含量分别为5.946、3.722 mg/g。
- Abstract:
- With seed coat of Ginkgo biloba as matierials,by the L9 (34) orthiogonal experiment,the Ginkgolic acid was extracted from Ginkgo biloba,the influences of the ratio of solid and liquid,extraction solvent concentration,time and temperature on the extraction effect were investigated.The results showed that the most important factor acid was temperature and the optimum reaction condition was:the ratio of solid and liquid 1∶40,90% methanol concentration,time 2.5 h,temperature 60℃.The best extraction content of Ginkgolic acid at 242 nm,310 nm were 5.946 mg/g and 3.722 mg/g.
