title: Effect of technological factors on concentration of halogen derivative pesticides in some vegetable drugs.
abstract: The effects of technological factors on degree of passing of halogen derivative pesticides (p,p'-DDT and its metabolites p,p'-DDD and p,p'-DDE, as well as HCH, DMDT, aldrin and dieldrin) from vegetable raw materials into infusions, decoctions, tinctures and dry extracts have been evaluated. It has been found that the quantity of isolated compounds depends mainly on type and concentration of solvent, temperature, duration of heating, type of raw material and its chemical composition. The highest extractions of these compounds have been observed with alcohol extracts, whereas in case of aqueous extracts the amounts extracted were much lower. In the case of tinctures the extraction amounted to approx. 90%, for dry extracts approx. 60%, for infusions approx. 25% and for decoctions only approx. 14%.
