Abstract: | In this paper the variation in the quantity and quality of the essential oil of Salvia officinalis during its life cycle stages is reported. The oils were obtained by hydrodistillation of air-dried samples. The yield of
essential oil (w/w %) in different stages was in the order: floral budding (0.9%) > vegetative (0.7%) > flowering (0.5%) >
immature fruit (0.4%) > ripen fruit (0.2%). The essential oils were analyzed by GC and GC-MS. In total, 36, 41, 40, 38, and
41 constituents were identified and quantified in the subsequent stages, respectively. Oxygenated monoterpenes were the main
group of compounds in the fruiting set (56.9%), vegetative (48.5%), flowering (47.7%), and floral budding (45.3%) stage. 1,8-cineole
as one of the major constituents of all samples was lower in the vegetative stage and gradually increased in subsequent harvesting
times to reach a maximum in flowering and then decreased in the fruiting set. In contrast, the globulol content was higher
in the first stage and decreased drastically during fruit maturation.
