Abstract:

Lavandula rejdalii Upson & Jury (L. rejdalii) is a Moroccan endemic plant, known for its medicinal and aromatic properties. However, little is known about its phytochemicals. In this work, L. rejdalii was investigated for its essential oil (LREO) yield and chemical composition determined by gas chromatogra- phy (GC/FID) and gas chromatography-mass spectrometry (GC/MS). Our results revealed that LREO contained twenty-six bioactive compounds representing 93.14 % of the total LREO composition. Likewise, hydrodistillation consistently resulted in higher LREO (0.83± 0.03 %). The main compounds revealed in LREO were linalool (32.03%), carvacrol (19.61 %), camphor (11.03 %), 1,8-cineole (9.67 %), linalyl acetate (9.02 %) and sabinene (3.81 %). L. rejdalii contained a higher level of oxygenated monoterpenes and phenols, which could be linked to impor- tant biological activities and promising potential applications as food preservatives, herbal formulations and also as disinfectants and antiseptics.

摘要：

薰衣草Upson＆Jury（L. rejdalii）是一种摩洛哥特有植物，以其药用和芳香特性而闻名。但是，对其植物化学成分知之甚少。在这项工作中，研究了赖氏乳杆菌的精油（LREO）收率和通过气相色谱（GC / FID）和气相色谱-质谱（GC / MS）测定的化学成分。我们的结果表明，LREO包含二十六个生物活性化合物，占总LREO组成的93.14％。同样，加氢蒸馏始终导致较高的LREO（0.83±0.03％）。LREO中发现的主要化合物为芳樟醇（32.03％），香芹酚（19.61％），樟脑（11.03％），1,8-桉树脑（9.67％），乙酸芳樟酯（9.02％）和sa烯（3.81％）。雷氏乳杆菌 含有较高含量的氧化单萜和酚，这可能与重要的生物活性有关，并有望作为食品防腐剂，草药制剂以及消毒剂和防腐剂应用。
