Relationship between Main Active Components of Ganoderma lu-cidum Cultivated under Forests and Ecological Factors
Environmental conditions are important factors that affect the formation and accumulation of active components of medicinal fungi.Grey correlation degree,CCA,PCA and other analysis meth-ods were used to explore the effects of ecological factors on the accumulation of main active compo-nents of Ganoderma lucidum cultivated under forests.Thirty samples of G.lucidum and thirty samples of soil were collected from deciduous broad-leaved forest in Helong city,Jilin province,and associated plants were recorded.The main active components of G.lucidum were determined by spectrophotom-etry.Soil temperature,water content,organic matter,etc.were determined by conventional methods.Air temperature and humidity meter and light meter were used to measure air temperature,humidity and light transmittance.The results showed that ecological factors had greater effects on polysaccharide,trit-erpene and protein content of G.lucidum,but less effects on amino acid content.Soil temperature and wa-ter content had significant effects on the accumulation of main active components of G.lucidum.Soil temperature was 19.50-24.25 ℃,and soil water content was 22.65％-49.49％,which is conducive to the accumulation of G.lucidum polysaccharide,total triterpenes and total protein content.
