Abstract

The species of the genus Salvia are known for their medicinal value due to the presence of chemical compounds or as they are known as secondary metabolites. These compounds are present in the aerial parts of the plant, mainly in their glandular trichomes. The purpose of this study is to evaluate the micromorphological structures of glandular trichomes and identify the secondary metabolites they contain in Salvia fruticosa Mill. in the Dhermi area, in South Albania. The histochemical technique used for the identification of secondary metabolites is the classical technique of staining the freehand sections of fresh plant material, which exploits the properties of certain reagents to form the chemical compounds containing glandular trichomes, stained products visible in the light microscope. Three main types of glandular trichomes were identified: peltate, capitate, and digitiforme. Peltate trichomes possess a basal cell, a short unicellular stalk, and a large secretory head with 8 secretory cells. Four types of capitate trichomes and a type of digitiforme trichome have been found in Salvia fruticosa Mill. Fenoles were detected at a high level at capitate trichomes type I and peltate trichomes. Proteins were detected at a high level at capitate trichomes type III. Alcaloides and tanines were detected at high levels at capitate trichomes type I, II, III and digitiforme trichomes. Tanines were detected at peltate trichomes too. Lipides were detected at high levels at capitate trichomes type II and III. Polisacharides were detected at high levels at capitate trichomes type II, III, IV, digitiforme, and peltate trichomes. Mucilages were detected at high level at capitate trichomes type III and peltate trichomes.
