  • Objective : To identify Semen Celosiae from different districts and its adulterant C.cristata L.. Methods : TG/DTA and thermal analyser were both used to scan and analyse the thermal map of Semen Celosiae from different districts and its adulterant Celosia cristata L.The experiment conditions are: asensitivity of ±50 uV,a calefactive rate of 15 ℃/min,an ambience of nitrogen and velocity of flow is 50 mL/min. Results :The thermal curves of Semen Celosiae and its adulterant Celosia.cristata L.represent that there were significant differences between them and each with characteristics,which means this experience has achieved an obverious differentiating effect. Conclusion :Differential thermal analysis method for accurate identification of traditional chinese medicine is simple,rapid and worthy of application.
