Abstract:

Abstract：The principal components analysis was adopted to investigate the vitamin efficiency of the Agaricus blazei MURILL under the condition of exogenous addition of Se. The results showed the VC was significant positive correlated with folacin and VB2; B5 was significant negative correlated with VB6 and VB1; VB1 and VB6, folacin and VB2 were significant positive correlated;others were not significant correlated. 3 main components which contributed the accumulative variance by 98.40% has been picked out from the 7 vitamin character indexes. According to the comprehensive function of each main component,the 3 main components could be explained respectively as the factor of VB5 and VC effect,the niacinamide effect and the folacin and VB2 effect. And the the equation of main components were as follows: y1=0.4112F1+ 0.4351F2-0.4057F3-0.3929F4+0.0270F5+ 0.4013F6+ 0.4013F7 y2=0.2931F1-0.2431F2+00.2940F3+0.3314F4+0.7175F5+0.2683F6+ 0.2683F7 y3=-0.1200F1-0.0483F2+0.3448F3+0.3341F4+-0.5962F5+0.4456F6+ 0.4456F7 The 40mg/Kg treatment had the highest principle components and integrate scores and it was the relatively suitable concentration.
