液体发酵得到的红栓菌（Ｐｙｃｎｏｐｏｒｕｓｃｉｎｎａｂａｒｉｕｓ）菌丝经沸水抽提，胰匀浆处理和Ｓｅｖａｇｅ法除蛋白，ＤＥＡＥＳｅｐｈａｄｅｘＡ－２５与ＳｅｐｈａｄｅｘＧ－１５０柱层析，乙醇沉淀得到二种多糖组分（简称ＰＣ＿１、ＰＣ＿２）。经聚丙烯酰胺电泳，冻融分析鉴定为均一体。ＰＣ＿１和ＰＣ＿２的，总糖含量分别为８１．５％和７７．３％，分子量分别为２３０００和１３０００．两者的红处光谱具多糖特征吸收峰，在紫外区无明显吸收现象，基本不含氮。ＰＣ＿１单糖组成为Ｄ－葡萄糖、Ｄ－半乳糖及Ｄ－甘露糖，ＰＣ＿２为Ｄ－半乳糖、Ｄ－甘露糖。
The mycelium of Pycnoporus cinnaabarius obtained by liquid fermentation was subjected to boiling water extraction, pancreatic homogenization and Sevage deproteinization. DEA Sephadex A-25 and Sephadex G-150 column chromatography were used to obtain two kinds of polysaccharides (PC_1, PC_2). Polyacrylamide electrophoresis, freeze-thaw analysis identified as homogeneous. The total sugar content of PC_1 and PC_2 were 81.5% and 77.3%, respectively, with molecular weights of 23000 and 13000, respectively. Both of the red spectral peak polysaccharide characteristics of absorption, no significant absorption in the ultraviolet region, the basic non-nitrogen. PC_1 monosaccharide composition of D-glucose, D-galactose and D-mannose, PC_2 of D-galactose, D-mannose.
