Microwave was applied to extract polysaccharides from Phoenix tea.Single-factor test and L_9(3~4) orthogonal experimental was used in study the influence factors of the solid-liquid ratio,microwave extraction time,microwave power,times of extraction and temperature on the content of polysaccharide.Experimental results showed that:the best extraction of Phoenix tea's polysaccharides conditions were 1:40 solid-liquid ratio,extraction time 120s,microwave power of 80%(640W),2 times,and 75℃.Microwave power is the most important factor,followed by the solid-liquid ratio and times of extraction,extraction time and temperature.
