Overall, 32 35 constituents detected , respectively, representing 92.4 93.1% total compositions. both species proved to reduce number lesions local host Chenopodium quinoa infected...

Abstract Satureja montana and S. subspicata are used as spice, pepper substitute, for preparing tea, juice, a medicine. Fourteen populations (seven per species) of L. Vis . growing in Croatia were examined to determine the chemical composition essential oil (analyzed by GC‐FID GC/MS), content macroelements (Na, K, Ca, Mg) trace elements (B, Fe, Cu, Mn, Zn, Al, Pb, Cr, Cd, Ni, Hg, As) analyzed ICP‐AES, antioxidant compounds UV/VIS spectrophotometer), types distribution trichomes scanning...

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 essential oil content (analysed by GC-FID GC-MS), phenolic HPLC), macroelements trace elements ICP-AES), quantity total phenols flavonoids UV/Vis spectrophotometer), antioxidant antimicrobial properties were investigated. The main phytol (21.13%),...

In this paper chemical composition of the essential oil (analysed by GC and GC-MS), content phenolic compounds HPLC), quantity total phenols flavonoids UV/Vis spectrophotometer), antioxidant antimicrobial activities ethanolic extracts were investigated in endemic Teucrium arduini L. population Mt Biokovo (Croatia).
