ABSTRACT
The structure and micromorphology of the glandular trichomes and the chemical composition of the secreted essential oil of Perovskia atriplicifolia Benth. were studied. The leaves present numerous glandular trichomes of three morphological distinct types, all of them having a unicellular foot and stalk: 1) capitate hairs with bi-cellular head, 2) peltate hairs with tetra-cellular head and 3) peltate hairs with multicellular (10-celullar) head. Qualitative and quantitative GC-MS analyses of the essential oils revealed limonene (18 %), γ – terpinene (16 %), β - caryophyllene (13 %), α - caryophyllene (12 %) and cymene (11%) as the main constituents.
