Abstract

L. samples, marketed in different geographic locations, were characterized by their organic and inorganic chemical composition. A total of 35 commercial samples were collected from various sites and analyzed to determine the qualitative and quantitative profile of essential oils, phenolic compounds and some inorganic elements. The variation in the content and composition of the essential oil was assessed by GC and GC-MS analyses, the phenolic fraction was investigated by UPLC/PDA, and the inorganic elements were determined by ICP-MS. The Principal Component Analysis (PCA) was applied with the aim to sort out the L. samples with different composition according to the different belonging origins. The results showed appreciable qualitative and quantitative differences among samples from different geographic origin.

摘要

在不同地理位置销售的L.样本，通过其有机和无机化学成分进行表征。从各个地点总共收集了35个商业样本，并进行分析以确定精油、酚类化合物和一些无机元素的定性和定量特征。通过气相色谱（GC）和气相色谱 - 质谱联用（GC-MS）分析评估精油含量和组成的变化，通过超高效液相色谱/光电二极管阵列检测器（UPLC/PDA）研究酚类部分，通过电感耦合等离子体质谱（ICP-MS）测定无机元素。应用主成分分析（PCA）的目的是根据不同的归属来源对具有不同组成的L.样本进行分类。结果表明，来自不同地理来源的样本在定性和定量上存在明显差异。
