(1) Background: The leaves of some plants are reported for their culinary uses, while in edible flowers, they are one of the discarded products in the supply chain. We investigated the volatile profile (VP) and the essential oil (EO) compositions of leaves from 12 Lamiaceae species, of which nine belong to the Mentheae tribe and three to the Ocimeae tribe. (2) Methods: Phytochemical analyses were performed using a GC-MS instrument. (3) Results: More than 53% of the Ocimeae tribe VP was represented by sesquiterpene hydrocarbons (SH), followed by phenylpropanoids, except for × where oxygenated monoterpenes (OM) were the second main class. OM prevailed in six species of the Mentheae tribe except for 'Arcado Pink', , and where SH dominated. The EO composition of Ocimeae tribe showed a similar behavior to that of VP concerning the predominant classes. 'Blue Spice' (Ob-BS) was an exception, since it showed oxygenated sesquiterpenes (OS: 29.6%) as a second principal class. Sesquiterpene compounds were also present in a high amount in two species of the Salviinae subtribe ( and ) and two of the Nepetinae subtribe ( × and 'Arcado Pink'). The remaining species of the Mentheae tribe were characterized by OM. (4) Conclusions: Many of the main compounds found were reported for their importance in human health and thus are important as ingredients in several new industrial products.
（1）背景：一些植物的叶子被报道具有食用价值，而在食用花卉中，它们是供应链中被丢弃的产品之一。我们研究了 12 种唇形科植物的叶片挥发性成分（VP）和精油（EO）组成，其中 9 种属于薄荷族，3 种属于罗勒族。（2）方法：使用 GC-MS 仪器进行植物化学分析。（3）结果：罗勒族 VP 的超过 53%由倍半萜烃（SH）组成，其次是苯丙素，除了 × ，其中含氧单萜（OM）是第二大主要类群。除了 'Arcado Pink'、和 ，薄荷族的六种植物以 OM 为主，而 SH 占主导地位。EO 组成在罗勒族中表现出与 VP 相似的行为，主要类群相似。'Blue Spice'（Ob-BS）是一个例外，因为它显示出第二大类含氧倍半萜（OS：29.6%）。两种 Salviinae 亚科（和 ）和两种 Nepetinae 亚科（ × 和 'Arcado Pink'）的两种植物也存在大量的倍半萜化合物。薄荷族的其余物种则以 OM 为特征。（4）结论：许多发现的主要化合物因其对人类健康的重要性而被报道，因此作为几种新工业产品的成分非常重要。
