分光光度法控制熏洗剂质量的研究

Application of spectral fingerprint Identification to fumigation prearetion

目的建立控制熏洗剂质量的光谱方法。方法采用紫外和红外两种分光光度法测定该制剂乙醇溶液的紫外光谱（UV）和氯仿萃取液的傅立叶变换红外光谱（FTIR）。结果5批熏洗剂的紫外和红外光谱都很相似，其图谱的吸收峰具有指纹特征。红外光谱存在10～12个共有特征吸收峰。紫外光谱227．00nm处的吸光度Amax分别为：0．9401，1．0078，1．1417，1．1278，1．2133，1．5123。结论这两种方法均简便，准确，灵敏，可作为该制剂的质量控制方法。

Objective To establish spectrophotometrys for control the quality of fumigation preparation. Methods Two spectrophotometrys were used. 95% ethanol solutions of 5 preparations were detected by ultraviolet spectrophotometry（UV）, and chloroform solutions of the preparations were detected by Fourier Transform Infrareds Spectroscopy（FTIR）. Results The UV and IR spectra of the solutions were of high similarity respectively, and the absorbance peaks of spectra had the characteristic fingerprint. Conclusion Two spectrophotometrys were all simple, accurate, sensitive, which could be used for the quality control of fumigation preparation.
