Rapid and Undamaged Assessment of Polysaccharide Content in Versicolor Extract by Near Infrared Spectroscopy
摘要
Abstract
In order to determinate polysaccharide content of Versicolor extract,the near-infrared scanning,spectral preprocessing spectral and band selection were carried out to establish Versicolor extract quantitative model by interval partial least squares (iPLS) and back interval partial least squares (Bi-PLS).The results showed that the second derivative(SD) pretreatment,the wave numbers range between 9 365.92 to 8 918.76cm-1 and 5 341.48 to 4 894.32 cm-1 can be better.The model of Real,RMSECV,Rval and RMSEP are 0.9089,0.00781,0.9879,0.00292 respectively.The model can effectively compress wavenumbers,reduce model’s complexity to achieve rapidly,nondestructive analysis of polysaccharide content in Versicolor extract.关键词
