The chemical composition of the essential oils of five populations of Hypericum triquetrifolium Turra from Tunisia and their intraspecific variability were analyzed in detail by GC/MS. One hundred seventy-four compounds were identified, representing averages of 87.9 to 98.7% of the oil composition. The components are represented here by homologous series of monoterpene hydrocarbons, oxygenated monoterpenes, sesquiterpenes hydrocarbons, oxygenated sesquiterpenes, non-terpenic hydrocarbons, and others. Sesquiterpene hydrocarbons were the most abundant chemical compounds. Multivariate chemometric techniques, such as cluster analysis (CA) and principal-component analysis (PCA), were used to characterize the samples according to the geographical origin. By statistical analysis, the analyzed populations were classified into four chemotype groups.
采用 GC/MS 详细分析了来自突尼斯的 5 个 Hypericum triquetrifolium Turra 种群的精油的化学成分及其种内变异性。鉴定出 174 种化合物，占油组成的 87.9%至 98.7%。此处通过同系物系列的单萜烃、含氧单萜、倍半萜烃、含氧倍半萜、非萜类烃和其他化合物来表示这些成分。倍半萜烃是最丰富的化合物。多元化学计量技术，如聚类分析（CA）和主成分分析（PCA），用于根据地理起源对样品进行特征描述。通过统计分析，将分析的种群分为四个化学型组。
