Study On Main Medicinal Composition Contents Under Different Growth And Development Stages Of Polyporus Umbellatus

Because of edible and medicinal fungi polyporus high medicinal value and economic value,and by the researchers at home and abroad to wide public concern.But because of its long growth cycle,low yield caused polyporus market in short supply situation.This test is to Changbai Mountain polyporus mycelium,Shanxi polyporus mycelium,Changbai Mountain polyporus sclerotia,Shanxi polyporus sclerotia,and Changbai Mountain polyporus fruiting body.And focus on the main efficacy of polyporus ingredients:polysaccharide and ergosterol,to determine the content and the comparative analysis.For polyporus mycelium instead of polyporus sclerotium,better use of polyporus medicinal value provided the scientific basis.The main research results are as follows:Polyporus mycelium from Shanxi polyporus look at pig faecium mycelium polysaccharide content is higher than that of Changbai Mountain polyporus mycelium and iron eggs polyporus mycelium.When the culture time is 21 days,this three kinds of mycelium polysaccharides content achieves the highest.The introduction and planting of Shanxi polyporus sclerotium polysaccharide content is the highest in polyporus sclerotia.And the grey polysaccharide content were all higher than black polysaccharide content.polyporus mycelium polysaccharide content is all higher than the polyporus sclerotia polysaccharide content.The ergosterol content is the highest when the Changbai Mountain mycelium is cultured 35 days.The Changbai Mountain polyporus sclerotia of family graft ergosterol content is the highest.While polyporus mycelium ergosterol content is always higher than polyporus sclerotia.Fruit body from Shulan polysaccharide content is higher than fruit body from Jiaohe.Fruit body from Shulan ergosterol content lower than fruit body from Jiaohe.
