Extraction of pyrethrum |
| abstract |
Pyrethrins are extracted from a solution of pyrethrum material in a low boiling hydrocarbon solvent with 4 to 8 C atoms into methanol or ethanol containing water. The pyrethrins are backextracted into the hydrocarbon solvent after adjusting the partition coefficients of the pyrethrins and non-pyrethrins. |
