中文摘要	为了建立一种基于红外光谱跟踪分析的过程分析方法用于团状雪灵芝(AP)提取分离过程的宏观指导,从同一工艺不同提取物及不同工艺同一提取物两个方面,对三种提取工艺各四种提取物进行红外光谱跟踪测试,并对红外光谱及相应二阶导数谱进行了深入的对比分析研究。光谱分析结果显示,同一工艺的不同提取物具有明显不同的光谱吸收特征;不同工艺同一提取物的吸收特征总体相似,但彼此之间也存在明显的光谱差异。1 603和1 123cm-1的特征峰表明,提取法一中,黄酮类及其糖苷主要进入了酯提物,余者进入了醇提物。相反,方法二、三中,大部分黄酮类进入了醇提物,水提物中还存在微量黄酮苷。此外,根据2 850cm-1峰强可知,方法二酯提物中苷元及高级饱和烃基含量较高。类似的,1 066和2 927cm-1等特征吸收峰表明方法三的醇提物中糖苷及多糖含量较高。研究结果表明,AP组分在不同提取工艺中的迁移规律不尽相同,提取过程中的物质迁移信息可以通过各提取物红外光谱的跟踪分析进行记录和直观解析。红外光谱跟踪分析法是一种快速、有效、低碳、环保的过程分析方法,对于诸如AP等植物提取分离过程的质量控制或工艺优化具有宏观指导意义。; In order to develop aprocess analysis method to guide extraction process of Arenaria polytrichoides(AP)based on tracking analysis by Fourier transform infrared(FTIR),IR spectra of petroleum ether extracts(PE-E),ethyl acetate extracts(EtOAc-E),n-butanol extracts(n-BuOH-E)and water extracts(H2O-E)of APfrom three extraction methods were recorded.The FTIR and corresponding second derivative infrared(SDIR)spectra were analyzed comparatively from two aspects,namely,different extracts from a same extraction process and the same extracts from different methods.The spectral analysis results show that different extracts obtained from a same extraction process have distinctly different spectral absorbance character.Although the IR spectral absorption characteristics of the same extracts from different methods are rather similar in holistic,some explicit spectral differences still could be found among each other.In extraction process one(M1),main flavonoids and their glycosides of AP migrated to EtOAc-E and the rest part of them shift to n-BuOH-E according to FTIR peaks such as 1 603and1 123cm-1.However,the circumstances in method two(M2)and method three(M3)were just the reverse.Moreover,a few flavonoid glycosides got into H2O-E.The relative content of all kinds of aglycones and higher saturated alkyl are much higher in EtOAc-E of M2 than that of M1 and M3according to the relative absorption intensive of peak at 2 850cm-1.Similarly,n-BuOH-E of M3 has relative rich contents of glycosides and polysaccharides than those of M1 and M2by peaks such as 1 066 and 2 927cm-1.These results demonstrate that the migration rules of APcomponents are not always same in different extraction process.The substance migration information during the extraction process could be recorded and disclosed in an intuitive way by FTIR tracking analysis of corresponding extracts.Consequently,FTIR tracking analysis is a fast,efficient,low-carbon and environment-friendly process analysis method.The method has important macro guiding significance for quality control and process optimization of extraction and isolation process of medicinal plant including AP.
