摘要:
目的 建立红外光谱技术,快速鉴别不同产地藿香的方法。 方法 采用傅里叶变换红外光谱技术和二维相关红外光谱法鉴定石牌广藿香(牌香),高要广藿香(肇香),海南广藿香(南香),湛江广藿香(湛香)等四种药材。结果 四种不同产地的广霍香(南香、湛香、牌香、肇香)的一维红外光谱和高分辨的二阶导数谱的结果相一致,确切地佐证了南香药材与其它三个产地药材相比具有明显的差异性,很好地解释了南香属于广藿香伪品的论证。二维红外相关谱表明:肇香在940 cm-1的自动峰最强,而牌香和湛香在947 cm-1为最强峰,两者相差了7个波数。湛香1151 cm-1的自动峰明显强于牌香的自动峰,另外湛香947 cm-1的交叉峰也明显强于牌香的交叉峰。凭借自动峰和交叉峰的强弱既可以作为鉴别相似度较大的牌香和湛香的依据。结论 红外光谱、二阶导数谱和二维相关红外光谱等三谱技术可以相互补充,相互佐证,可以鉴别四种广藿香的产地,同时也可以看到肇香与牌香、湛香的品质相近,但不完全相同,品质最差的是南香,即海南产的广藿香。
Abstract:
ObjectiveTo establish the infrared spectroscopic technique to identify pogostemon cablins from different areas.Methods Fourier transform infrared spectroscopy and two-dimensional infrared correlation spectroscopy analysis were used to identify pogostemon cablins, including Paixiang, Zhaoxiang, Nanxiang and Zhanxiang.Results The results of one-dimensional infrared correlation spectroscopy were consistent with those of second derivative spectroscopy, which indicated that Nanxiang was markedly different from the other three varieties, leading support to the argument that Nanxiang was a fake pogostemon cablin. The result of two-dimensional infrared correlation spectroscopy suggested that the strongest automatic peak of Zhaoxiang was at 940 cm-1 while that of Paixiang and Zhanxiang was strongest at 947 cm-1. Moreover, the auto peak of Zhaoxiang was stronger than that of Paixiang at 1151 cm-1 and the cross peak of Zhaoxiang was stronger than that of Paixiang at 947 cm-1. Therefore, the intensity of auto peak and cross peak served as a good criterion for the differentiation between Paixiang and Zhanxiang.Conclusions Infrared spectroscopy, second derivative spectroscopy and two-dimensional correlation spectroscopy could be applied to identify four different pogostemon cablins. The analysis revealed that the quality of Zhaoxiang is similar to those of Paixiang and Zhanxiang, yet not completely the same. Nanxiang, which grows in Hainan province, has the worst quality.
