用统一的提取分离方法对葛根和小蓟药材进行处理,然后测定其提取物的红外光谱。结果显示:不同采集时间葛根和小蓟的红外光谱具有很好的特征性、稳定性和可重复性;粉葛根的红外光谱也具有很高的特征性。根据红外光谱可以非常准确地鉴别葛根和小蓟。

Extracts of Radix Pueraria and Herba Cirsii, obtained by the same isolating procedure,were examined with IR spectra. Results showed that the IR spectra of Radix Pueraria and Herba Cirsii,collected at different times had distiuct characteristics,consistency aud repcatability.The spectra of Radix Pueraria thomsonii also showed characteristic evidence.Accordingly, Radix Pueraria and Herba Cirsii may be well distinguished by means of IR spectra.
