In this study, the changes caused by variation of altitude to the essential oils (EOs), fatty acid methyl esters (FAMEs), and antimicrobial activities of Primula vulgaris Huds. subsp. vulgaris ( Pvv) and P. vulgaris Huds. subsp. sibthorpii (Hoffmanns) W.W. Sm. & Forrest ( Pvs)) grown in Turkey were investigated. Major fluctuations in the composition of Pvv and Pvs oils included methyl-4-methoxy salicylate (4.5–35.3%; Pvv and 3.2–37.2%; Pvs), ( Z,Z,Z)-7,10,13-hexadecatrienal (5.1–21.8%; Pvv and 4.4–15.2%; Pvs) and flavone (5.5–14.9%; Pvv and 1.6–18.0%; Pvs). Fatty acid profile (C6:0–C26:0) changes were noted in Pvv and Pvs. Methyl hexadecanoate (2.4–9.3%) and methyl octadecanoate (1.0–4.7%) were present in all the FAME samples of the plants. The antimicrobial activity of the EOs of Pvv and Pvs were tested against nine bacterial species, which showed activity against Mycobacterium smegmatis with minimum inhibitory concentrations (MIC) varying from 8.5 to 59.2 μg/mL in all samples, respectively, depending on the altitude at which the oils were obtained.

In this study, we tested whether the addition of fatty acid methyl esters (FAME) of edible oils would influence the herbicidal effect of the essential oils (EO) of fiber hemp and peppermint (Mentha×piperitaL.) against common lambsquarters, barnyardgrass, and corn. The herbicidal properties of a 2.5% concentration of each EO in water mixtures with FAME were evaluated as sprays in a pot experiment. The oil-FAME mixtures showed phytotoxic effects against common lambsquarters and barnyardgrass expressed by a reduction in plant length and aboveground and root biomass, as measured three weeks after foliar spraying. Corn was the most tolerant species to the tested mixtures. Sunflower FAME alone was safe on corn but reduced the growth of weeds. Peppermint EO alone was the most phytotoxic on all tested species. In conclusion, the mixture of peppermint EO with oilseed rape FAME was the best treatment; however, improvement onCh. albumwould be desirable for commercial-level control.
