Composition of essential oils from leaves and flowers of Stachys germanica subsp. salviifolia (Ten.) gams (Labiatae) and related secretory structures

Nat Prod Commun. 2009 Jun;4(6):831-4.

Abstract

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.
