Abstract The composition of the essential oils from different aerial parts of Lavandula coronopofolia Poiert (syn. Stricta delile L.) (Lamiaceae) was studied for the first time and analyzed by GC/MS. The oils were isolated separately by hydrodistillation from flowering tops, leaves, and from the whole aerial parts collected during the flowering period and the vegetative phase of the plant. The oil yield obtained from flowering tops, leaves, and whole aerial parts were 7.1%, 0.6% and 1.47%, respectively. Thirty-four compounds in the oil were identified. Linalool, camphor, terpinen- 4-ol, 1,8-cineole and borneol were found to be the major constituents. The oil composition was found to vary by plant part. Linalool (41.2%) was found to be the major constituent in flowering tops and leaves, whereas, 1,8-cineole (25.4%) was the major constituent in the whole aerial parts oil. Thymol and carvacrol, which were minor components in the leaf oil, were found to be 13 and 11 times greater in the flowering tops oil.
