Sažetak
Dalmatian pyrethrum (Tanacetum cinerariifolium /Trevir./ Sch. Bip.) is a plant species endemic to the east Adriatic coast. The bioactive substance of Dalmatian pyrethrum is a natural insecticide, pyrethrin, a mixture of six active components (pyrethrin I and II, cinerin I and II and jasmolin I and II). The insecticidal potential of pyrethrin was recognized decades ago, and dried and ground flowers have traditionally been used in Croatian agriculture and households. A total of 25 Dalmatian pyrethrum populations from Croatia were studied to determine the pyrethrin content and composition, and to identify distinct chemotypes. The total pyrethrin content ranged between 0.36% and 1.30% (dry flower weight ; DW) and the pyrethrin I / pyrethrin II ratio ranged between 0.64 and 3.33. %. The statistical analyses revealed that the correlations between the % of pyrethrin I and of all the other components were significant and negative. The total pyrethrin content was positively correlated with the % of pyrethrin I and negatively correlated with cinerin II. The multivariate analysis of the chemical variability enabled the identification of five chemotypes among 25 Dalmatian pyrethrum populations. The chemical characterization of indigenous Dalmatian pyrethrum populations may serve as a good background for future breeding and agricultural exploitation.
