This study presented a micromorphological and phytochemical survey on Lavandula dentata L. cultivated at the Ghirardi Botanic Garden (Toscolano Maderno, BS, Italy). The morphological investigation revealed the presence of peltate, short‐ and medium‐stalked capitate trichomes. The histochemical survey showed terpene production by peltates and medium‐stalked capitates, hydrophilic secretions by short‐stalked capitates. The phytochemical survey was developed on leaf and flower volatile organic compounds (VOCs) and on the essential oil (EO) from the flowering aerial parts. The VOC profiles represented an element of novelty and were dominated by oxygenated monoterpenes, among which 1,8‐cineole and β‐pinene were the most abundant (77.40 %, 7.11 % leaves; 81.08 %, 10.46 % flowers). The EO of L. dentata was dominated by oxygenated monoterpenes with a high percentage of 1,8‐cineole (69.08 %), followed by β‐pinene, trans‐pinocarveol and myrtenal. Evaluations about the ecological role, the potential biological activity and the sensory attributes were proposed, based on literature contributions.

薰衣草 来自意大利：毛状体和挥发物分析

本研究对 Ghirardi 植物园（Toscolano Maderno，BS，Italy）种植的 Lavandula dentata L. 进行了微形态学和植物化学调查。形态学调查显示存在盾形、短柄和中柄头状毛。组织化学调查表明，盾形动物和中柄头状动物产生萜烯，短柄头状动物产生亲水性分泌物。植物化学调查是针对叶子和花朵的挥发性有机化合物 (VOC) 以及开花地上部分的精油 (EO) 进行的。VOC 谱代表了一种新元素，主要是含氧单萜，其中 1,8-桉树脑和 β-蒎烯含量最高（77.40%，7.11% 叶；81.08%，10.46% 花）。L 的 EO dentata 主要是含氧单萜，1,8-桉树脑（69.08 %）的比例很高，其次是 β-蒎烯、反式松香芹醇和桃金娘。在文献贡献的基础上，提出了对生态作用、潜在生物活性和感官属性的评估。
