    Abstract：ObjectiveStudy the optimum extraction condition for acid polysaccharide from pine seed shells.MethodsThe effects of four factors such as the temperature of extraction, the time of extraction, the proportion of water volume, the number of extraction on the extraction of the hot water were investigated. With the orthogonal design of L9(34).ResultsThe optimum conditions of extraction were obtained as follows: Temperature was 80℃, 2 hours evevy time, ratio of solid-liquid 1∶3.5, extraction twice.ConclusionThis process was stable and acid polysaccharide content was high. ......
