Glandular trichomes and essential oils of Salvia glutinosa L.
A Kaya, B Demirci, KHC Baer
Abstract
The aerial organs of Salvia glutinosa L. bear indumentum with two types of
trichomes: simple and multicellular nonglandular trichomes, and stalked and
sessile dense glandular trichomes. Glandular trichomes are extremely
long-stalked and dense on the stem and calyx surfaces. However, sessile glands
are rare on the stem, calyx and leaf adaxial surfaces and dense on the leaf
abaxial surface. Secretion accumulates in a subcuticular space and is released
to the outside by cuticle rupture. Water distilled essential oil from dried
aerial parts of S. glutinosa was analysed by GC/MS. The main constituent
was identified as 1-octadecanol (11.6%).
