Abstract: Objective To identify different breeds of Fagopyrum tataricum by differential thermal analysis and near infrared reflectance spectroscopy. Methods TG/DTA and thermal analysis were both used to scan and analyze the thermal map of 11 breeds of F. tartaricum. The experiment conditions included DTA range of ±50 μV, a calefactive rate of 15 ℃/min, an ambience of nitrogen and flow velocity of 50 ml/min. Bruker Vector 22/N-type Fourier transform near infrared spectroscopy was used to scan and analyze of 11 breeds F. tartaricum. Experiment conditions were: integrating sphere diffuse reflectance as measure methods; scan for 64 times; 3 700 ~ 12 000/cm as scan range. Results Both methods could identify the Jiande tartary buckwheat from other breeds. Conclusion Jiande tartary buckwheat was a new cultivar, nutrient value and pharmacological activity of which should be evaluated for promotion. -
