采用红外光谱、二阶导数光谱和二维相关红外光谱对大别山地区和云南省两大道地主产区的茯苓皮进行鉴别分析。结果表明,不同产地茯苓皮的红外光谱都有1149,1079和1036 cm -1等表征糖类成分的特征吸收峰,其中大别山产区(湖北省、安徽省)的茯苓皮中1619,1315和780 cm -1等表征草酸钙的特征吸收峰比较显著,云南产区的茯苓皮中797,779,537和470 cm -1等表征硅酸盐的特征吸收峰更加明显。比较450~1650 cm-1波数范围内的二阶导数红外光谱可知,两个产区茯苓皮所含糖类物质有所不同。在二维相关红外光谱中,不同产地茯苓皮所含糖类物质的差异更加直观显著。红外光谱法直观、简单、方便、快速,可以作为鉴别不同产地茯苓皮,诠释产地与药效之间关联性的一种有效准确的新方法。
採用紅外光譜、二階導數光譜和二維相關紅外光譜對大彆山地區和雲南省兩大道地主產區的茯苓皮進行鑒彆分析。結果錶明,不同產地茯苓皮的紅外光譜都有1149,1079和1036 cm -1等錶徵糖類成分的特徵吸收峰,其中大彆山產區(湖北省、安徽省)的茯苓皮中1619,1315和780 cm -1等錶徵草痠鈣的特徵吸收峰比較顯著,雲南產區的茯苓皮中797,779,537和470 cm -1等錶徵硅痠鹽的特徵吸收峰更加明顯。比較450~1650 cm-1波數範圍內的二階導數紅外光譜可知,兩箇產區茯苓皮所含糖類物質有所不同。在二維相關紅外光譜中,不同產地茯苓皮所含糖類物質的差異更加直觀顯著。紅外光譜法直觀、簡單、方便、快速,可以作為鑒彆不同產地茯苓皮,詮釋產地與藥效之間關聯性的一種有效準確的新方法。

Different geographical regions of traditional Chinese medicine (TCM ) ,its chemical composition is different ,the accu-mulation of drug and medicinal properties is different .The accurate identification and analysis of different production area of me-dicinal herbs is critical for the quality control and pharmacological research of TCM .In this paper ,a tri-step infrared spectrosco-py (Fourier transform infrared spectroscopy (FTIR) combined with second derivative spectra and two-dimensional correlation in-frared spectroscopy (2D-COS) were employed to identify and analyze the main components of Hubei(HB) ,Anhui(AH) ,Yun-nan(YN) genuine Poria Cocos peels .The emergence of several characteristic absorption peaks of carbohydrates including 1 149 , 1 079 1 036 cm -1 ,peaks around 1 619 ,1 315 ,780 cm -1 belonged to calcium oxalate suggested that HB and AH Poria Cocos peels contained calcium oxalate ,but peaks around 797 ,779 ,537 ,470 cm -1 belonged to kaoline suggested that YN Poria Cocos peels contained kaoline .Their carbohydrates were different by comparing the second derivative infrared spectra in the range of 1 640~450 cm -1 and Yongping come from YN contains both calcium oxalate and kaoline .Furthermore ,the above differences were visually validated by two-dimensional correlation spectroscopy (2D-COS) .It was demonstrated that the Tri-step infrared spectroscopy were successfully applied to fast analyze and identify Poria Cocos peels from different geographical regions and sub-sequently would be applicable to explain the relevance of geographical regions and medicinal properties for the TCM .
