摘要
从云头状灵芝[Ganoderma Lucidum(Leyss.ex Fr.)Karst.]中分离得到三种灵芝多糖BN3A,BN3B及BN3C,它们均表现明显免疫调节作用。从灵芝多糖BN3B及BN3C中各分离得到四个多糖均一体,对其中主要成分BN3C1,BN3C3,BN3B1及BN3B3进行了物理及化学研究,它们的平均分子量依次为1.6×10^4,2.5×10^4,3.5×10^4及4.0×10^4。经完全酸水解、红外光谱测定、过碘酸氧化、甲酸生成、Smith降解等证明,BN3B1及BN3C1均为β-(1→6)(1→3)甙键相连的葡聚糖。BN3B3为阿拉伯半乳聚糖。BN3C3为由葡萄糖和阿拉伯糖组成的肽多糖。它们均为β-(1→6)(1→3)甙键相连。
