摘　　要：用正交实验探讨了银杏叶总黄酮类化合物的最佳提取工艺和银杏叶总黄酮保健饮料的最佳配方 .研究结果表明 :在 80℃条件下 ,用 5倍于叶重体积的 70 %乙醇回流提取 2次 ,时间为 2 h/ 1 .5h的效果最好 .银杏叶总黄酮保健饮料最佳配方 :液体为每 1 0 0 m L饮料中银杏叶总黄酮含量 1 5mg,糖量 1 0 g,柠檬酸 0 .0 6 g,β- CD量 0 .0 4 5g;固体饮料为白砂糖粉 85% ,糊精 9% ,柠檬酸 5% ,香精 0 .7% ,银杏叶总黄酮 0 .3% .The optimum extracting conditions of flavonids in folium ginkgo and the best dispensing of the folium ginkgo healthy beverage were investigated by using orthogonal design. The results showed that 80 ℃ , 5∶1 of 70% ethanol to folium ginkgo weight ratio, extracted two times during 2 h/1.5 h for two times were optimal. The optimum formula of healthy beverage with folium ginkgo flavones were: 15 mg folium ginkgo flavones, 10 g sucrose, 0.06 g citric acis, 0.045 g β CD per 100 mL liquid beverages and 85% sucrose powders, 9% dextrin, 5% citric acis, 0.7% essence, 0.3% folium ginkgo flavones for granular beverages.
