摘要: 以银杏叶浸取液为研究体系,对溶剂气浮法分离富集银杏叶黄酮进行了研究. 考察了气浮溶剂种类、气浮溶剂与料液体积比(Vs/Vi)、表面活性剂种类及浓度、溶液pH、气浮气速和气浮时间对气浮效率的影响. 结果表明,以正辛醇为气浮溶剂、正辛醇与料液体积比1:10、表面活性剂SDBS浓度100 mg/L、料液pH 3.0、气速100 mL/min、气浮时间60 min为最佳操作条件,在此条件下,黄酮类化合物的富集比与回收率分别为5.73和59.76%.

Abstract: Solvent sublation was applied to separate and enrich flavone from Ginkgo biloba leachate system. The effects of solvents, volumetric ratio of solvent to aqueous solution (Vs/Vi), type and concentration of surfactant, pH, gas flow rate and sublation time on the floatation efficiency were investigated. The results showed that the optimized operating conditions were octanol as sublation solvent, Vs/Vi value at 1:10, concentration of sodium dodecyl benzene sulfonate at 100 mg/L, pH value at 3.0, gas flow rate at 100 mL/min and sublation time for 60 min. Under the above conditions, the enrichment ratio and recovery rate of flavone reached 5.73 and 59.76%, respectively.

Key words: solvent sublation, enrichment ratio, recovery rate, Ginkgo biloba leachate, flavone
