Essential Oil Composition of Five Collections of Achillea Biebersteinii from Central Turkey and their Antifungal and Insecticidal Activity

Abstract

The composition of the essential oils hydrodistilled from the aerial parts of five Achillea biebersteinii Afan samples, collected in central Turkey from Konya, Isparta and Ankara, were analyzed both by gas chromatography (GC-FID) and gas chromatography-mass spectrometry (GC-MS). Eighty-four components were identified, representing 87 to 99% of the total oil composition. The identified major components were 1,8-cineole (9-37%), camphor (16-30%) and p-cymene (1-27%). Two samples differed in piperitone (11%) and ascaridol (4%) content. The five A. biebersteinii essential oils were subsequently evaluated for their antifungal activity against the strawberry anthracnose-causing fungal plant pathogens Colletotrichum acutatum, C. fragariae and C. gloeosporioides using the direct overlay bioautography assay. The essential oils showed no antifungal activity at 80 and 160 µg/spot. In addition, A. biebersteinii oils and their major compounds were subsequently investigated against Aedes aegypti first instar larvae in a high throughput bioassay. Among the oils, only one sample from Ankara showed a notable larvacidal effect on Ae. aegypti larvae. The major compounds, 1,8-cineole, camphor and p-cymene, exhibited low mosquito larval activity, and thus the minor compounds are probably responsible for the observed activity against Ae. aegypti larvae. The oils showed weak activity against adult Ae. aegypti.

Biological Activity of Bunium persicum Essential Oil from Western Himalaya

“…The authors attributed this high inhibitory activity to cumin aldehyde and p-cymene [32]. In our previous antifungal studies, we demonstrated that EOs rich in non-oxygenated monoor sesquiterpenes did not show good antifungal activity [33,34]. Therefore, the antifungal effect of B. persicum oil might either be correlated to p-mentha-1,4-dien-7-al, p-mentha-1,3-dien-7-al, or cumin aldehyde in accordance with [32], or attributable to possible synergistic effects of one or more compounds present in the oil.…”

GC‐MS Analysis: In Vivo Hepatoprotective and Antioxidant Activities of the Essential Oil of Achillea biebersteinii Afan. Growing in Saudi Arabia

“…biebersteinii collected from East Azerbaijan, Iran, where α -terpinene (41%) and p -cymene (13%) were the major components [ 24 ]. Other reports on the chemical composition of A. biebersteinii essential oil from Turkey and Iran showed a main chemotype which is characterized by the presence of 1,8-cineole (9–37%) and camphor (16–30%) as major components [ 4 , 25 , 26 ]. Moreover, the GC-MS analysis of the oil of A. biebersteinii collected from Sivas in Turkey has resulted in the identification of piperitone (35%) and eucalyptol (13%) as the main components [ 6 ].…”

Effect of vegetable oil (Brazil nut oil) and mineral oil (liquid petrolatum) on dental biofilm control

“…13 Essential oils are used in medicine, cosmetics and the food industry, and their volatile components possess antimicrobial, antifungal and insecticide activity. 14 The activity of essential oils in dental biofilm inhibition and reduction has been reported, 15 and these properties are derived from the absorption to dental enamel that results in a hydrophobic surface and reduces dental biofilm deposition. 16 Favorable antibacterial activities of two essential oils (Mentha piperita and Cuminum cyminum) against Streptococcus mutans and Streptococcus pyogenes were recently reported.…”
