Multiple enzymatic assisted microwave technology was used to extract tea polyphenols from Tea. The results showed that the optimal technology of multiple enzymatic was the cellulase dosage accounting for 1% dry raw material weight, pecti-nase dosage accounting for 0.5% dry raw material weight, and the extraction temperature of 60 ℃ for 30 min. The optimal condition for microwave extraction was using: distilled water as extraction solvent, feeding pump frequency of 9 Hz, the mi-crowave power of 36 kW, the proportion of raw material to solvent of 1:10 (m:m)and extraction once. Under the optimal con-dition, the extraction rate of tea polyphenols was 25.19%. Compared with other methods, it was rapid, environment friendly and selective.
