Abstract
Tea polysaccharide(TPS)extracting from common green tea was studied by orthogonal design method with four factors such as the ratio of tea to water,temperature,time and extracting times.The results showed that the primary affecting factor for TPS extracting rate was the ratio of tea to water,the next was in order of temperature,extracting times and time and the optimal condition:with 1:25 ratio of tea to water extracting once for 90 min at 85℃.
