本文尝试用裂解—毛细管气相色谱法鉴定中草药,对十四种中草药的裂解行为进行了探讨。通过比较各中草药裂解色谱图中的特征峰或八个主要峰的保留值和相对强度,借以鉴定中草药;通过比较不同产地中草药特征峰的强度,借以评价中草药的质量。文中还对用裂解色谱法鉴定中草药的条件进行了探讨。由实验结果初步看出,裂解色谱法是可以鉴定和评价中草药的。
This article attempts to use cracking - capillary gas chromatography identification of Chinese herbal medicine, fourteen kinds of Chinese herbal medicine cracking behavior were discussed. By comparing the characteristic peaks or the retention and relative intensities of the eight major peaks in each Chinese herbal medicine chromatogram, the Chinese herbal medicine can be identified; the quality of the Chinese herbal medicine can be evaluated by comparing the intensities of the characteristic Chinese herbal medicine herbs in different areas. In this paper, the conditions for the identification of Chinese herbal medicine by using pyrolysis chromatography are also discussed. Preliminary results from the experiment found that pyrolysis chromatography is the identification and evaluation of Chinese herbal medicine.
