Laurus nobilis L. is an aromatic shrub or tree, Mediterranean element. The leaves are employed as a spice and for medicinal purposes. It is known by various names in Turkey, such as "defne, har and tehnel." In this study, 15 different laurel leaf samples were purchased from 6 different cities in Turkey, diagnosed, and evaluated in terms of quality. The conditions of use and sale of these samples were evaluated. The essential oils obtained from the leaf samples were analyzed, and their physical properties such as density, refractive index, and optical rotation were determined. In the chemical composition of the oils, 1,8-cineole (41.2-64.4%), sabinene (1.5-15.9%), and α-terpinyl acetate (1.5-15%) have been found to be the major components. However, in one station, the presence of 1,8-cineole was not be determined. Laurel leaf drugs offered for sale in some provinces of Turkey were purchased from the market and their morphological characteristics and essential oil profiles were examined and evaluated in terms of public health. It was determined that these samples should be standardized and quality-controlled before being released to the market.
月桂（Laurus nobilis L.）是一种芳香的灌木或乔木，属于地中海地区的特有物种。其叶片被用作香料和药材。在土耳其，它有“defne、har 和 tehnel”等不同的名称。在这项研究中，从土耳其的 6 个不同城市购买了 15 种不同的月桂叶样本，对其进行了诊断，并根据质量进行了评估。评估了这些样本的使用和销售条件。对从叶样本中获得的精油进行了分析，并确定了它们的物理性质，如密度、折射率和旋光度。在油的化学成分中，发现 1,8-桉叶素（41.2-64.4%）、柠檬烯（1.5-15.9%）和α-萜品醇乙酸酯（1.5-15%）为主要成分。然而，在一个站点，没有检测到 1,8-桉叶素的存在。从土耳其一些省份的市场上购买了出售的月桂叶药物，并对其形态特征和精油图谱进行了检查和评估，以确保公共卫生安全。确定在将这些样本投放市场之前，应对其进行标准化和质量控制。
