Abstract: The taxonomic status and biological characteristics of wild sanghuang body collected from Xixia county,Nanyang city,Henan Province were studied by means of morphological identification,phylogenetic analysis and single factor test.At the same time,the contents of polysaccharides,flavonoids,polyphenols and saponins in Sanghuanmporus sanghuang,Sanghuangporus vaninii and Inonotus hispidins were compared,in order to enrich the resources of Sanghuangporus.The results showed that the strain belonged to S.sanghuang.Under pure culture conditions,the optimum temperature,pH,carbon source and nitrogen source were 26-28℃,pH 6,maltose and glucose,and yeast extract and tryptone.The contents of active components of three kinds of sanghang were significantly different.Among them,the contents of flavonoids and total phenols in S.sangh uang were the highest,and the contents of polysaccharides and saponins in S.vaninii were the highest.In summary,the wild sanghuang body collected from Henan Province was S.sanghuang and it had higher medicinal value in sanghuang fungi.
