Composition of essential oils from leaves and flowers of Stachys germanica subsp. salviifolia (Ten.) gams (Labiatae) and related secretory structures.
The essential oils from both leaves (L) and flowers (F) of Stachys germanica subsp. salviifolia (Ten.) Gams (Labiatae/Lamiaceae) from Italy were analyzed by GC-MS for the first time. The distribution, morphology and histochemistry of the different types of glandular trichomes present on the epidermal surface were also determined. Twenty-nine constituents, representing 89.4% of the total leaf oil, and forty-one compounds, forming 97.8% of the total flower oil, were identified. Germacrene D (39.4%), phytol (10.2%), beta-bourbonene (3.5%) and beta-ylangene (3.3%) were recognized as the main constituents of the leaf essential oil, while limonene (24.1%), beta-pinene (18.7%), germacrene D (12.8%) and (E)-nerolidol (6.6%) were the main compounds of the flower essential oil.
