Artificial Cultivation Formula Selection and Polysaccharide Content Determination of Polyporus umbellatus
In order to shorten the cultivation cycle,increase production,improve quality,the agricultural waste resources and crushed corn cob,cotton seed hull,Quercus sawdust were used as the basic raw material for artificial cultivation of Polyporus umbellatus,to find the best mix of raw materials and cultivation conditions.The results showed that the growth cycle of P.um-bellatus was shortened to 120 days by using cottonseed hulls and Quercus sawdust as raw material,mature P.umbellatus indi-vidual large and structure was more compact.The high-performance liquid chromatography(HPLC)was used for quantitative and qualitative analysis of active ingredient polysaccharides,and it was found that its composition and content were comparable to that of wild P.umbellatus.
