Chemical composition and insecticidal activity of edible garland (Chrysanthemum coronarium L.) essential oil against the granary pest Sitophilus granarius L. (Coleoptera)

Abstract

The essential oil composition and biological activities of Chrysanthemum coronarium L. from three locations in Cyprus were investigated. A total of 35 components were identified in the oils representing 86.2 ± 0.7%–93.8 ± 0.0% (n = 3) of the oils. Camphor 25.2 ± 0.1%–9.1 ± 0.3%, santolinatriene 21.7 ± 0.1%–3.6 ± 0.1%, yomogi alcohol 12.6 ± 0.1%–3.6 ± 0.1%, cis-chrysanthenyl acetate 10.7 ± 0.1%–6.8 ± 0.1% and bornyl acetate 11.0 ± 0.5%–5.7 ± 0.0% were identified as the main components. Highest DPPH scavenging and PRAP activity was observed for the Lefkoşe sample (49.59 ± 0.19% (n = 5) and 812.77 ± 4.34 AU (n = 5)). Highest phytotoxic activity against Lemna minor L. was observed for the Salamis sample (100.0%). Lefkoşe sample showed the highest insecticidal activity (97.82 ± 1.79% mortality, S. granarius). Bornyl acetate/cis-chrysanthenyl acetate/hexadecanoic acid and camphor/santolinatriene/ yomogi alcohol chemotypes of C. coronarium are proposed from Cyprus samples according to cluster analysis of the oils together with the literature data.
