Abstract

Chemical profiles of essential oils hydrodistilled from whole plants of Senecio glaucus ssp. coronopifolius (Maire) Alexander and aerial parts of Ridolfia segetum (L.) Moris growing in Morocco were determined using gas chromatography/mass spectrometry (GC/MS). The analysis identified 84 compounds in the oil isolated from S. glaucus ssp. coronopifolius and 61 constituents in R. segetum oil. Both oils had a predominance of monoterpene hydrocarbons. α-Pinene (26.2 %) was the main compound of S. glaucus ssp. coronopifolius oil, followed by myrcene (11.4 %) and p-cymene (9.9 %). Novelly (Z)-β-ocimene (19.7 %) dominated R. segetum oil, followed by β-phellandrene (9.6 %) and β-pinene (8.6 %). This is the first report of (Z)-β-ocimene-rich essential oil from R. segetum and α-pinene-rich essential oil from S. glaucus ssp. coronopifolius, revealing new chemical profiles for both species. The oils have potential in agroecological and pharmaceutical formulations, serving both economic and medicinal applications.

摘要

从千里光（Senecio glaucus ssp）的整个植物中蒸馏得到的精油的化学特性 使用气相色谱/质谱法（GC / MS）测定了摩洛哥的coronopifolius（Maire）亚历山大和Ridolfia segetum（L.）Moris的空中部分。该分析鉴定出从S. glaucus ssp分离的油中有84种化合物。coronopifolius和61成分在R.地老虎油。两种油均以单萜烃为主。α-P烯（26.2％）是S. glaucus ssp的主要化合物。冠毛油，其次是月桂烯（11.4％）和对异丙基苯（9.9％）。（Z）-β-ocimene（19.7％）占主导地位R. segetum油，其次是β-水芹烯（9.6％）和β-pine烯（8.6％）。这是来自R. segetum的富含（Z）-β-ocimene精油和来自S. glaucus ssp的富含α- pine烯的精油的首次报道。coronopifolius，揭示了两个物种的新化学特征。这些油在农业生态和药物配方中具有潜力，可用于经济和医学应用。
