The present study aimed to chemically characterize 31 accessions and seven cultivars of basil. The percentage composition of the essential oils of the accessions and cultivars was based on the 14 most abundant constituents: 1,8-cineole, linalool, methyl chavicol, neral, nerol, geraniol, geranial, methyl cinnamate, β-bourbonene, methyl eugenol, α-trans-bergamotene, germacrene-D, epi-α-cadinol, and δ-cadinene. The genetic materials were classified into eight clusters according to the chemical composition of the essential oils: Cluster 1--mostly linalool and 1,8-cineole; Cluster 2--mostly linalool, geraniol, and α-trans-bergamotene; Cluster 3--mostly linalool, methyl chavicol, methyl cinnamate, and β-bourbonene; Cluster 4--mostly linalool, methyl chavicol, epi-α-cadinol, and α-trans-bergamotene; Cluster 5--mainly linalool, methyl eugenol, α-trans-bergamotene, and epi-α-cadinol; Cluster 6--mainly linalool, geraniol, and epi-α-cadinol; Cluster 7--mostly linalool and methyl chavicol; Cluster 8--mainly geranial and neral.
本研究旨在对31份罗勒种质资源和7个罗勒品种进行化学特征分析。这些种质资源和品种的精油成分百分比基于14种含量最丰富的成分：1,8-桉叶素、芳樟醇、甲基丁香酚、橙花醛、橙花醇、香叶醇、香叶醛、肉桂酸甲酯、β-波旁烯、甲基丁香酚、α-反式佛手柑油烯、杜松烯-D、表-α-荜澄茄醇和δ-荜澄茄烯。根据精油的化学成分，这些遗传材料被分为8个聚类：聚类1——主要为芳樟醇和1,8-桉叶素；聚类2——主要为芳樟醇、香叶醇和α-反式佛手柑油烯；聚类3——主要为芳樟醇、甲基丁香酚、肉桂酸甲酯和β-波旁烯；聚类4——主要为芳樟醇、甲基丁香酚、表-α-荜澄茄醇和α-反式佛手柑油烯；聚类5——主要为芳樟醇、甲基丁香酚、α-反式佛手柑油烯和表-α-荜澄茄醇；聚类6——主要为芳樟醇、香叶醇和表-α-荜澄茄醇；聚类7——主要为芳樟醇和甲基丁香酚；聚类8——主要为香叶醛和橙花醛。
