【Abstract】 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.更多还原
