灵芝子实体多糖和三萜含量变化规律

The Changes of the Content of Polysaccharide and Triterpene in Fruiting Bodies of Different Varieties of Ganoderma

设计不同质量的栽培基质和不同的成熟度,旨在对不同品种灵芝子实体产量和活性成分的关系以及变化规律进行研究。结果表明:金大灵芝和硫因灵芝FQ16栽培料越多,产量越高,与最低组间有显著差异;赤芝和鹿角灵芝子实体产量在处理组间无显著差异;灵芝子实体的多糖和三萜含量随栽培料质量增加均呈无规律变化。硫因灵芝FQ16不同成熟期,菌盖形成期多糖含量最高,达61.31±2.92 mg/g;成熟期三萜的含量最高,达8.92±0.78 mg/g。研究结果:显示灵芝的子实体产量与栽培料质量呈量的关系,在满足其生长条件下,培养料的增加灵芝子实体产量不会增加;灵芝多糖和三萜含量与栽培料质量无显著相关性。硫因灵芝FQ16不同成熟阶段多糖和三萜含量有显著差异,生产上根据产品要求选择合适成熟阶段采摘灵芝。

In this paper,four kinds of Ganoderma were used as materials to study the variation of yield and active components of different varieties of Ganoderma through the design of different weights of cultivation substrates and different maturity.The results showed that the yield of Ganoderma lucidum strain JINDA and G.resinaceum strain FQ16 was higher with more cultivated materials,and there was significant difference between them and the lowest group.There was no significant difference in fruiting body yield between Ganoderma lucidum strain CHIZHI and Ganoderma amboinens in the same groups.The contents of polysaccharide and triterpene of Ganoderma varied irregularly with the increase of the weight of cultivation material.The content of polysaccharide of G.resinaceum FQ16 was the highest at the pileus formation stage,which was 61.31±2.92 mg/g.The content of triterpenes in mature stage was the highest,reaching 8.92±0.78 mg/g.The results indicated that the fruit body yield of Ganoderma did not increase,when the weight of cultivation material increased under the cultivation material meet their growth.There was no significant correlation between the contents of polysaccharide and triterpene of Ganoderma and the weight of cultivation material.Strain FQ16 had significant difference in content of polysaccharide and triterpene under different maturity stages.So we could pick the fruit body of Ganoderma at the appropriate maturity stage according to product requirements.
