Abstract The composition of the essential oil from a Thymus vulgaris L. type growing wild in northern Italy was determined by GC and GC‐MS. Forty‐four components of the oil were identified, monoterpenes being the most abundant (about 80%). The biogenetic sequence γ‐terpinene → p ‐cymene → thymol probably defines the chemotype. The effect of environmental conditions over the two consecutive trial years was evaluated with respect to the quali‐quantitative composition of the essential oils and some agronomic parameters.
