Sažetak
Tea made from Veronica spicata L. (syn. Pseudolysimachion spicatum (L.) Opiz, family Plantaginaceae) herb is used in traditional medicine as expectorant for cough and throat rinsing. To get insight into chemical compounds of V. spicata, the chemical composition of the essential oil (analysed by GC-FID and GC-MS), the content of macroelements and trace elements (analysed by ICP-AES), the content of phenolic compounds (analysed by HPLC), quantity of total phenols and total flavonoids (analysed by UV/Vis spectrophotometer), and antioxidant and antimicrobial activities were investigated. The major compounds of essential oil were phytol (21.1%), heptacosane (10.2%) and pentacosane (8.9%). The most abundant investigated macroelement was K (8261 mg/kg) while Fe was the most represented element (32.49 mg/kg) among investigated micronutrients. Ten phenolic compounds (chrysin, rutin, quercitrin, quercitrin, and cichoric, ferulic, protocatehuic, rosmarinic, syringic and tannic acid) were identified and quantified. Additionally, the results showed that V. spicata is a source of polyphenolic and other antioxidants with radical-scavenging and chelating properties. The bacterial and fungal strains used in study were found to be susceptible toward methanolic and ethyl-acetate extracts with MIC values between 1.25 and 5 mg/mL.
