Abstract:With dry loquat leaves as raw material， we used the method of water-extraction and alcohol-precipita－ tion， optimized the technological conditions of microwave-assisted extraction through the single-factor and or thogonal experiment. The results showed that the optimal extracting conditions were liquid-solid ratio 1 ∶ 20（g/mL）， microwave power 640 W and microwave treatment time 150 s， the extraction rate could be up to 10.350 mg/g.
