Abstract:
Taking Gentiana scabra Bunge as material,the method of water extraction and alcohol sink were used to extract water solubility polysaccharides from the Gentiana scabra Bunge.The influence of extraction temperature，extraction time，extraction number and ratio of water to raw material on the yield of Gentiana scabra Bunge polysaccharides (GSP) were investigated by L9(33) orthogonal test.The results showed that the extraction temperature was 100℃，ratio of water to raw material was 1∶25，extraction time was 3.0 h，and extraction times was two.Under the optimize conditions，the experimental yield of GSP could reach (14.0±0.37)%.
