Sažetak
Micromeria kerneri Murb. is an endemic Illyric-Balcanic species distributed in Bosnia and Herzegovina, Croatia, and Montenegro from sea level up to 250 m. Types and distribution of trichomes, and chemical composition of the essential oil were investigated in M. kerneri Murb. (Lamiaceae) growing in Gradina near Šibenik, Croatia. Non-glandular trichomes, peltate and two types of capitate trichomes (type 1: one basal epidermal cell, one elliptically shaped head cell ; oblique ; type 2: one basal epidermal cell, two stalk cells, and one head cell ; upright) were observed on leaf, stem and calyx, using scanning electron microscopy. Water distilled essential oils from aerial parts of investigation plant have been analysed by GC and GC/MS using VF-5ms capillary column. The total yield of oil was 0.06%, based on dry weight of samples. Fifty-four compounds representing 96.9% of the total oil of M. kerneri. This essential oil was characterized by a high concentration of oxygenated sesquiterpenes (42.9%) of which caryophyllene oxide being the principal compound (39.2%). β-Pinene (6.3%), docosane (5.4%), camphor (4.3%), and E-caryophyllene (2.9%) were the other main components of the investigation oil. The present study gives additional knowledge about micromorphological traits and essential oil contents on the genus Micromeria, and especially on endemic M. kerneri.
