Abstract: By using tea seed as test material, the effect on ethanol concentration, microwave power, extraction time, solid-liquid ratio and other factors on the extracting yield of tea seed saponin were studied in order to comprehensive exploitation and utilization of tea seed saponins resources, and the optimum technology parameter of microwave assisted extraction of tea seed saponin were obtained. The result showed that extraction parameters of saponin from tea seed by ethanol volume fraction 60%, microwave power 539βW, auxiliary extraction time 7βmin, solid-liquid 1︰50, and the tea saponin yield reached 18.56%, which increased 6.84%, and 6.22% respectively compared to the conventional water extraction method and ethanol extraction method. Besides, the extracting time was shorten signicantly.
