Chemical Profile, Elemental Composition, and Antimicrobial Activity of Plants of the Teucrium (Lamiaceae) Genus Growing in Moldova

Teucrium L. is a widely distributed genus often used for the treatment of digestive disorders and respiratory problems. The aim present study was to determine chemical composition essential oils elemental content plant species polium, hircanicum, botrys, chamaedrys, flavum, orientale, scordium Moldovan origin, as well evaluate antimicrobial activity their extracts. determined using gas chromatography–mass spectrometry (GC–MS), neutron activation analysis (NAA) assess plants. Antimicrobial tests were performed in vitro on Bacillus subtilis, Pseudomonas fluorescens, Xanthomonas campestris, Erwinia amylovora, carotovora, Candida utilis strains double-dilution method. GC–MS allowed identification 59 components analyzed oils, showed that belong four different chemotypes. Using NAA, 18 major minor elements, contents which fell within value ranges reported other medicinal herbs this genus, identified. hydroalcoholic extracts from spp. exhibited antibacterial antifungal at 0.03–0.06% 0.015–0.03%, respectively. high activity, enabling application medical purposes.
