灵芝品种子实体多糖和三萜含量分析与评价

Analysis and Evaluation of Polysaccharides and Triterpenes Contents of Fruitbody of Ganoderma lucidum strains

为了选育加工专用型灵芝品种,以灵芝多糖和三萜含量为评价指标,对12个灵芝品种的子实体多糖和三萜含量进行了分析评价。结果表明,不同灵芝菌株的子实体在多糖和三萜含量上存在着一定的差异,其中多糖以薄树灵芝、日本红芝、仙芝、京大、树舌灵芝含量高,三萜含量却以京大、赤芝05、惠州、信州、树舌灵芝、松杉灵芝、日本红芝含量高,并且二者的含量不存在显著的相关性,这为选育灵芝多糖、灵芝三萜含量均高,并适合精深加工专用的灵芝品种提供了理论依据。

Polysaccharides and triterpenes contents of fruitbody of 12 Ganoderma lucidum strains were determined in order to choose special strains for extraction and processing. The results showed that the polysaccharides contents of the strains were different, and the polysaccharide contents of G. capense, Japanese G. lucidum, G. lucidum XIANZHI, G. lucidum JINGDA and G. applanatum were higher. While the triterpenes contents of G. lucidum JINGDA, G. lucidum 05, G. lucidum HUIZHOU, G. lucidum XINZHOU, G. applanatum, G. tsugae and Japanese G. lucidum were higher. There was no distinct correlation between polysaccharides and triterpenes contents of fruitbody of Ganoderma lucidum. These results provided the theoretical basis for the select and breed of special strains for processing, which Ganoderma lucidum polysaccharides and triterpenes contents are both higher.
