Abstract:
Taking A.mongholicus seedlings as experimental materials,the effects of cultivated and imitating wild on the estimation methods of astragaloside and calycosin-7-glucoside content in A.mongholicus were studied by using hyperspectral and multiple linear regression methods,in order to provide reference for the rapid and accurate estimation of the medicinal composition content of cultivated and imitating wild A.mongholicus in practice.The results showed that the stability and the fitting degree of the models established by the raw hyperspectral data of medicinal composition content of cultivation and imitating wild A.mongholicus were the best.The RMSE of the models to estimate the astragaloside content were 0.004 5,0.008 5;the R2 were 0.761,0.879;the models were y=0.005 4+0.001 6x1+0.000 2x2+0.000 7x3(R2=0.903),y=-0.122 3+0.004 0x1+0.000 1x2-0.000 9x3(R2=0.904),respectively.The RMSE of the models to estimate the calycosin-7-glucoside content were 0.001 7,0.004 0;the R2 were 0.860,0.868;the models were y=0.073 1-0.008 0x1-0.000 4x2+4×10-6x3(R2=0.891),y=0.084 2-0.000 7x1-0.000 1x2+0.000 2x3(R2=0.883),respectively.
