摘要
目的：不同产地青葙子及其混淆品鸡冠花子的鉴别。方法：应用TG／DTA联用热分析仪分别对不同产地的青葙子和鸡冠花子进行差热图谱扫描与分析。实验条件为差热量程：±50uV；升温速率：15℃／min；升温范围：30℃～700℃；气氛为N2，流速：50mL／min。结果：青葙子及其混淆品鸡冠花子的热谱曲线各具特征性且差异明显，取得了良好的鉴别效果。结论：差热分析方法用于中药鉴别准确、简便、快速，值得推广应用。
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 ealefaetive 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 ubverious differentiating effect. Conclusion： Differential thermal analysis method for accurate identification of traditional chinese medicine is simple, rapid and worthy of application.
