| Abstract: | With loquat leaf as the raw material, the main factors affecting the extraction rate of flavonoids from it were investigated. Based on single-factor experiments, orthogonal tests were conducted to optimize the technological conditions for the extraction of flavonoids. The results showed that the optimum conditions included ethanol volume fraction 60%, solid-to-solvent ratio 1：25 （g/mL）, microwave temperature 65℃ and microwave treatment time 7 min. The extraction rate of flavonoids reached up to 16.24% under the optimal extraction conditions. |
