Take of honeysuckle leaves as raw material,by using water bath shaking extraction,single factor and orthogonal experiment,the effects of extraction temperature,time and liquid to solid ratio on the extraction rate of chlorogenic acid and flavonoids were investigated,flavoring extract with white sugar.The results showed that the best extraction temperature was 90 ℃,the extraction time was 60 min,liquid to solid ratio was 60 ∶1,the extraction rate of chlorogenic acid and flavonoids reached 75.51% and 82.31% r...
