摘要: Mung bean (Vigna radiata L.) is rich in D-chiro-inositol (DCI), vitexin, and isovitexin, which has beneficial effects on antidiabetic and inhibits the formation of advanced glycation end-products. In this study, near-infrared reflectance spectroscopy (NIRS) was used to predict the contents of DCI, vitexin, and isovitexin in mung bean. The spectra data were linearized with those determined by high-performance liquid chromatography (HPLC). The models for predicting the DCI, vitexin, and isovitexin contents in ming bean were developed using partial least-squares (PLS) algorithm. Cross-validation procedures indicated good correlations between HPLC data and NIRS predictions (R(2)=0.90 for DCI, R(2)=0.81 for vitexin, and R(2)=0.90 for isovitexin). The predictive contents of DCI, vitexin, and isovitexin ranged from 2.082 to 3.084%, 1.277 to 1.307%, and 0.5998 to 0.6286%, respectively. The results showed that NIRS, a well-established and widely applied technique, could be applied to rapid detection of DCI, vitexin, and isovitexin contents in mung bean.
