摘　　要：为探究不同野生灵芝的主要活性成分以及对野生灵芝的开发利用价值,对13种野生灵芝菌株在同一条件下进行液体发酵,采用化学分析的方法,比较菌丝体胞内三萜和多糖的含量差异。结果显示,13种灵芝菌株的三萜和多糖含量有很大差异,其中无柄紫灵芝Ganodermamastoporum、亮盖灵芝G.lucidum和树舌灵芝G.applanatum的三萜含量较高;树舌灵芝G.applanatum、紫芝G.sinense和褐灵芝G.brownii的多糖含量较高。目前国内广泛栽培灵芝G.lingzhi的野生菌株发酵产物中的三萜和多糖含量并不是最高的,研究结果表明不同种类的野生灵芝还有进一步挖掘的潜在价值。Thirteen species of wild Ganoderma were isolated,and liquid fermentation was conducted under the same conditions to compare their content of intracellular triterpenoids and polysaccharides.The results showed that the content of triterpenoids and polysaccharides was significantly different among 13 Ganoderma species.The content of triterpenoids was higher in Ganoderma mastoptorum,G.lucidum and G.applanatum than that in other tested species,and the content of polysaccharides was higher in G.applanatum,G.sinense and G.brownii than that in other tested species.The wild strain of nowaday widely cultivated G.lingzhi produced less triterpenoids and polysaccharides as compared with other wild Ganoderma species tested.Our results show that there are still more Ganoderma species having potential value for further exploration.
