The aim of this study was to establish a rapid method to analyze the volatile components of Artemisiae Argyi Folium and to study the content and distribution characteristics of Artemisiae Argyi Folium from different habitats. The volatile components were investigated by headspace solid-phase microextraction gas chromatog.-mass spectrometry (HS-SPME-GC-MS) based on the Agilent productivity Chem Station and were quantified roughly by peak area normalization method. The data were analyzed by principal component anal. (PCA) and cluster anal. (CA). Eighty-four components were identified preliminarily, which were mainlyketones, alkenes, aldehydes and alcs. There were significant differences in essential components of Artemisiae Argyi Folium from different habitats. It could be distinguished effectively by principal component anal. and cluster anal. The quality of Artemisiae Argyi Folium from Qichun of Hubei province was the best, followed by from Guangbu of Hunan province and Tangying of Henan province. The results of the cluster anal. revealed five main clusters. The method was reliable and stable. This method could be applied to analyze the volatile components of Artemisiae Argyi Folium. It would provide the scientific basis for quality assessment of Artemisiae Argyi Folium. In the experiment, the researchers used many compounds, for example, 1-Chlorooctadecane (cas: 3386-33-2Recommanded Product: 1-Chlorooctadecane).
1-Chlorooctadecane (cas: 3386-33-2) belongs to organic chlorides. Organic chlorides can cause corrosion in pipelines, valves and condensers, and cause catalyst poisoning. The hydrocarbon processing industry (HPI) and others are affected by damage caused by these substances.While alkyl bromides and iodides are more reactive, alkyl chlorides tend to be less expensive and more readily available. Alkyl chlorides readily undergo attack by nucleophiles.Recommanded Product: 1-Chlorooctadecane
