Pyrethrin content and composition of Dalmatian pyrethrum (Tanacetum cinerariifolium /Trevir./ Sch. Bip.) populations from Croatia

摘要: Pyrethrin is a potent natural insecticide derived from Dalmatian pyrethrum (Tanacetum cinerariifolium /Trevir./ Sch. Bip.), plant species endemic to the east coast of Adriatic Sea. has highly unusual insecticidal activity, with ability control or repel numerous insect species, little no adverse environmental impact. Its use represents safe and efficient method control. A total 25 wild Bip.) populations different geographical origin Croatia were studied focus on determining pyrethrin content composition. Active components extracted acetone by means ultrasound-assisted extraction six identified quantitatively determined high performance liquid chromatography coupled diode array detector. The ranged between 0.36 1.30 % dry flower weight, an average 0.86 %. I / II ratio 0.64 3.33 1.91. Statistical analyses revealed that correlations all other significant negative. Total was positively correlated negatively cinerin II. Multivariate analysis chemical variability enabled identification five chemotypes among analyzed populations. most abundant chemotype including eight characterized lower higher I, jasmolin With growing interest in organic farming as well increased resistance pests synthetic pesticides more strict legislation, been expanding continuously recent years. Our results show are valuable source genetic be exploited breeding programs great commercial value for agricultural utilization.
