Abstract: Using limewater as solvent, rutin was extracted with the operation of microwave. The optimum technology conditionswere obtained as follows: crushing the flower bud scholartree to (0.28mm<d<0.45mm), extracted 2 times by microwave, water-material ratio 1:16, time 10min and power defrost. Then filtered and regulating the filtrate’s pH2~3 with hydrochloric acid, addingsurfactant OP and laid about 30min to deposit completely , filtered and washed with water, dried the residue, was the rutinproduct obtained. The yield was 17.1% and content was about 94.1%. The results demonstrated that less time,less energy andhigher extracting rate by microwave treatment were obtained in comparison with traditional boiling water extraction.
