Origanum vulgare L. belonging to the Lamiaceae family, commonly known as oregano, is one of the most traded and consumed medicinal plants worldwide. It is a rich natural source of specialized metabolites including essential oils. The present study is the first comprehensive account of the essential oil profile of wild O. vulgare subsp. viride plants in Iran. Twenty native populations from four provinces of northern Iran were investigated for the content and composition of essential oils. Essential oil contents were found to vary from 0.1 to 0.5% (v/w) based on dry weight. Analysis of these oils by GC-FID and GC-MS resulted in a total of forty-nine constituents, representing 96.2–99.7% of the total compositions. The subsequent classification of the studied populations by multivariate statistical procedures characterized four chemotypes: i) γ-terpinene/p-cymene; ii) linalool/α-phellandrene; iii) sabinene; and iv) carvacrol/trans-caryophyllene. These data may be useful in the future selection of populations comprising specific chemical characteristics for industrial purposes, and furthermore contribute beneficial information for developing conservation strategies, domestication and breeding programs of Iranian O. vulgare subsp. viride germplasm.

Origanum vulgare L. 属于唇形科，俗称牛至，是全球交易量和消费量最大的药用植物之一。它是包括精油在内的特殊代谢物的丰富天然来源。本研究是对野生O 的精油分布的第一个综合描述。普通亚种 绿色伊朗的工厂。调查了来自伊朗北部四个省的 20 名当地居民的精油含量和成分。发现精油含量基于干重从 0.1% 到 0.5% (v/w) 不等。通过 GC-FID 和 GC-MS 对这些油进行分析，得到总共 49 种成分，占总成分的 96.2-99.7%。随后通过多变量统计程序对研究人群进行的分类表征了四种化学类型：i) γ-萜品烯/对伞花烃；ii) 芳樟醇/ α-水芹烯；iii) 桧烯；iv) 香芹酚/反式-石竹烯。这些数据可能有助于未来选择包含特定化学特征的工业用途种群，并进一步为制定伊朗O 的保护策略、驯化和育种计划提供有益信息。普通亚种 绿色种质。
