ABSTRACT Essential oils (EOs) of eight Artemisia specieswere analyzed by gas chromatography-mass spectrometry (GC/MS) and gas chromatography/flame ionization detector (GC-FID) at vegetative, budding and flowering stages. Regarding the cluster analysis and principal component analysis, group A of cluster analysis (A. campestris) was highly correlated with Methyleugenol and Acenaphthylene and group B of cluster analysis (A. spicigeria, A. sieberi, A. annua, A. vulgaris and A. diffusa(were highly correlated with 1,8-cineole and Camphor. Also group C of cluster analysis (A. absinthium and A. scoparia) were highly correlated with β-Pinene. Methanol crude extracts of leaves of Artemisia species were obtained at vegetative stage. Antioxidant activities by DPPH and Reducing Power (RP) methods, flavonoid and flavonol contents by aluminum chloride (AlCl3) and total phenols by Folin-ciocalteu assay were measured. The greatest amount of antioxidant activity, TP, TF and TFl were found in A. scoparia and the lowest in A. vulgaris.

伊朗蒿属植物精油的化学成分：使用多元统计分析的比较研究

摘要 采用气相色谱-质谱 (GC/MS) 和气相色谱/火焰离子化检测器 (GC-FID) 在营养、萌芽和开花阶段对八种蒿属植物的精油 (EO) 进行了分析。在聚类分析和主成分分析方面，聚类分析的 A 组（A. campestris）与甲基丁香酚和苊，聚类分析的 B 组（A. spicigeria、A. sieberi、A. annua、A. vulgaris 和 A. . diffusa（与 1,8-桉树脑和樟脑高度相关。聚类分析的 C 组（A. absinthium 和 A. scoparia）与 β-蒎烯高度相关。阶段. DPPH 和还原功率 (RP) 方法的抗氧化活性，测定了氯化铝 (AlCl3) 测定的类黄酮和黄酮醇含量，以及 Folin-ciocalteu 测定法测定的总酚含量。抗氧化活性、TP、TF 和 TF1 在 A. scoparia 中发现的量最大，在 A. vulgaris 中最低。
