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

WOS: 000423634600006

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 Lefkoe 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%). Lefkoe 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.
