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 lefkose 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%). lefkose 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.
