【摘要】 从灵芝中分离得到免疫活性多糖BN₃B,进一步分离纯化得到4个多糖均一体,对其中主要成分BN₃B₁及BN₃B₃进行化学研究证明,BN₃B₁为含β-（1→6）及（1→3）甙键的葡聚糖,BN₃B₃为含β-（1→6）及（1→3）甙键的阿拉伯半乳聚糖。更多还原

【Abstract】 BN₃B, the polysaccharide component of the fruit of Ganoderma lucidum, has been shown to have immune activity. From BN₃B four homogeneous polysaccharides were separated and purified. Chemical studies on the main components BN₃B₁ and BN₃B₃ indicated that BM₃B₁ contained only glucose and should he a gtuean containing β-（1→6）and （1→3）glycoside bonds and that BN₃B₃ was an arabinogalactan containing β-（1→6）and（1→3）glyeoside bonds.更多还原
