| Abstract: | The functional components of P. LobataWere analyzed rapidly by Near Infrared (NIR) spectral technology. The optimum conditions of mathematics model of five components (total isoflavones, puerarin, daidzin, starch, crude protein)were studied.The results demonstrated that the correlation between the chemical value (true value)of the five components of sample set and the NIR predicated value is 0.9752,0.9839,0.9659,0.9628 and 0.9829, respectively. The correlation between the chemical value of the testing sample set and the NIR predicated value is 0.9818,0.9752,0.9772,0.9737,0.9798, respectively. It proved that the mathematical model that we established have practical value. |
