In this paper,preliminary study on the active components of A.camphorata by solid state fermentation is conducted.The results showed that it contains many kinds of active components,including maleic and succinic acid derivatives,adenosine,sterols,polysaccharides and higher fatty acids.The solid state fermentation of A.camphorata have two kinds of liver protective components antrodin B and antrodin C.The content of adenosine,cordycepin,and Ergostatrien-3β-ol in A.camphorata were 5.15 mg/g,0.178 mg/g and 11.02 mg/g,respectively.In addition,the content of active polysaccharides β-1,3-D-glucan was 102.4 μg/g.Unsaturated fatty acids from the solid state fermentation production was the advantageous fatty acid,and the contents was 81.96 %,in which oleic acid and linoleic acid were the main components.
