Extraction efficiency of insecticidal active compounds from dried Dalmatian pyrethrum flowers (Chrysanthemum cinerariaefolium /Trevir/Vis) was tested using different techniques and solvents.
Joffe et al. found that the most effective natural synergists that increase the efficiency of pyrethrum extract were parsley seed oil and dillapiole, the main ingredient in dill

SFE is a highly efficient process that has exceptional solvent properties due to the supercritical phase. Therefore, the oleoresin can be obtained with a good yield directly
This approach enabled us to simulate two-component fluid dynamics in a SFE extraction system, namely modelling of the diffusion of pyrethrum essential oil (dispersed

- What determines the quality of pyrethrum extract?
- Besides the total pyrethrin quantity, the important factor that determines the quality of the pyrethrum extract is the content of pyrethrin I component, as well as a pyrethrin I/pyrethrin II (PI/PII) ratio.
- Does dried Dalmatian pyrethrum flower extract insecticidal active compounds?
- Extraction efficiency of insecticidal active compounds from dried Dalmatian pyrethrum flowers (Chrysanthemum cinerariaefolium /Trevir/Vis) was tested using different techniques and solvents.
- What is RP-HPLC method for pyrethrin extraction?
- Kasaj et al. (1999) have developed a simple, fast, and precise RP-HPLC method for the separation and quantification of the six pyrethrins from pyrethrum flowers, after the individual pyrethrins were isolated from the extract by preparative NP-HPLC.
- How does pyrethrum extract work?
- Pyrethrum extract is usually combined with the semi-synthetic synergist piperonyl butoxide (PBO), which increases its effective toxicity, preventing insects from “coming back to life” by inhibiting/deactivating specific P450 enzymes.
