对来自意大利北部利古里亚和艾米利亚地区的牛至原生种群的精油含量和成分进行了分析。形态特征表明利古里亚样品属于亚种。绿色。花序的精油含量范围从艾米利亚样品中的小于 5 mg g(-1) 到一些利古里亚样品中的超过 50 mg g(-1)，值与 ssp 报道的值相似。来自意大利南部的希尔图姆。精油中鉴定出 64 种化合物。根据油成分将样品分为三个主要组：第一组属于香芹酚/百里酚生物合成途径的成分含量较高；第二组属于香芹酚/百里酚生物合成途径的成分含量较高。第二种的特点是具有不同的倍半萜成分和高芳樟醇含量；第三个，包括两个ssp样本。来自艾米利亚的 vulgare 的特征是含有丰富的倍半萜烯。研究样品的高精油含量以及一些特殊形态特征的存在表明O. vulgare的分类学，特别是在其西部分布区，需要进一步研究。芳樟醇类型虽然通常不被认为是“典型的牛至”，但可能有助于促进该物种生物多样性的更广泛利用。 (C) 2000 年植物学公司年鉴。
Native populations of Origanum vulgare L. from the Liguria and Emilia regions of northern Italy were analysed for essential oil content and composition. Morphological characters suggested that the Ligurian samples belonged to the ssp. viride. The essential oil content of inflorescences ranged from less than 5 mg g(-1) in the samples from Emilia, to more than 50 mg g(-1) in some Ligurian samples, values similar to those reported for ssp. hirtum from southern Italy. Sixty-four compounds were identified in the essential oil. The samples were allotted to three main groups on the basis of oil composition: the first group had a high content of components belonging to the carvacrol/thymol biosynthetic pathway; the second was characterized by a different sesquiterpene composition and a high linalool content; and the third, including the two samples of ssp. vulgare from Emilia, was characterized by the presence of abundant sesquiterpenes. The high essential oil content of the samples studied, and the presence of some particular morphological characters suggest that the taxonomy of O. vulgare, especially in its western distribution area, needs further investigation. Linalool types, although often not considered as 'typical oregano', may be useful in promoting wider utilization of the biodiversity of this species. (C) 2000 Annals of Botany Company.
