Sažetak
Micromeria pseudocroatica Šilić is an endemic species distributed in southern Croatia. Chemical composition of the essential oil (analysed by GC and GC-MS), and the content of macroelements and trace elements analysed by ICP-AES was conducted. Additionally, a study on the types and distribution of trichomes was done by scanning electron microscopy. The essential oil was characterized by a high concentration of oxygenated monoterpenes, whose major compounds are borneol (22.7% and 24.8%) and camphor (16.1% and 13.9%). The content of Ca was highest (13202.69 mg/kg and 13223.83 mg/kg) among the investigated macroelements, while Fe was the most represented element (100.68 and 326.48 mg/kg) among the micronutrients. The content of potentially toxic elements that is Se, Cu, and Hg was below the limit of quantification. Non-glandular trichomes, peltate trichomes, and two types of capitate trichomes (type 1: one basal epidermal cell, one head cell with subcuticular space ; type 2: one basal epidermal cell, two stalk cells, and one head cell with subcuticular space) were observed on leaves, bracteoles, calyx, corolla and stem.
