Abstract
In the Iberian Peninsula the three rosemary species Rosmarinus officinalis, R. eriocalyx and R. tomentosus are endemic.
In this work, plant material from spontaneous populations of R. officinalis was collected in different locations from the Spanish region of Andalucia: Almeria, Cadiz, Cordoba, Granada, Jaen, Malaga and Sevilla, in order to select those populations with the highest essential oil yield and the best profile according to the International Standard Limits (ISL) on Oil of Rosemary (2nd edition, 2000) by Gas Chromatography; the chromatographic profile for the Spanish type indicates a minimum percentage of 18% α-pinene, 8% camphene, 2% ß-pinene, 2.5% myrcene, 2.5% limonene, 17% 1,8-cineol, 1% ρ-cymene, 12.5% camphor, 0.4% bornyl acetate, 1% α-terpineol, 2% borneol and 0.7% verbenone, and a maximum content of 26% α-pinene, 13% camphene, 5% ß-pinene, 4.5% myrcene, 5.5% limonene, 25% 1,8-cineol, 2% ρ-cymene, 22% camphor, 2.5% bornyl acetate, 3.5% α-terpineol, 4.5% borneol and 2.5% verbenone.
Moreover, essential oil use in human therapy is increasing during last years because of its antimicrobial activity and mainly due to its antioxidant ability.
Our results show a great diversity in the essential oil composition and generally most components have lower values than the inferior limits demanded by the International Standard quality rules.
The chemical analysis shows the potential of essential oil from R. officinalis that can be used for the treatment of several diseases.
