title: [The rapid analysis of functional components of P. Lobata by near infrared spectrum].
abstract: The functional components of P. Lobata were analyzed rapidly by near infrared (NIR) spectral technology. The optimum conditions of mathematics model of three components (total isoflavones, puerarin, daidzin) were studied, including the sample set selection, chemical value analysis, the detection methods and conditions. The analytical results demonstrated that the correlation between the chemical value (true value) of the three components of sample set and the NIR predicated value is 0.975, 0.984, 0.996, respectively. The correlation between the chemical value of the testing sample set and the NIR predicated value is 0.982, 0.975 and 0.981, respectively. It proved that the mathematical model that we established can be used in practice.
