中文摘要：

采用傅里叶变换红外光谱及其二阶导数谱对动物药全蝎由表及里8个部位的药材粉末进行了分析与评价。结果表明，全蝎不同部位的红外光谱较为相似，而二阶导数红外光谱中峰位置和峰强度的差异明显。全蝎不同部位的分析结果进一步证明：蛋白质是每个部位的主体成分，但蝎尾的蛋白质与其他部位较为不同；脂肪类物质主要集中于躯于部分；硫酸粘多糖普遍存在于每个部位。此外，变质的全蝎在躯干后部含有较多量的嘌呤类似物。因此，傅里叶变换红外光谱及其二阶导数谱不仅可以为药材不同部位的差异分析和评价提供了一种快速、全面和客观的方法和手段，而且可以为药理研究等提供合理的方向性指导。

英文摘要：

Fourier transform infrared （FTIR） spectroscopy and second derivative IR spectroscopy were applied to analyze and evaluate different parts of Scorpio. The second derivative IR spectra show clear differences while the origin spectra are quite similar. It was found that proteins are the dominant components in each part and the tail has distinct proteins compared to the others; fats are mainly stored in the trunk; sulfates are ubiquitous in all parts. Interestingly, the back part of the trunk of degenerative Scorpio contains some purine. It was demonstrated that FTIR spectroscopy integrated with second derivative IR spectroscopy not only can offer a fast, comprehensive and objective methodology for analyzing and evaluating the micro-differences among the various parts of same medicinal materials, but also can provide a rational guidance for medicinal and pharmacological studies.
