Mycotoxin, fruit Aspergillus

We should also mention that LiChrolut EN was successfully used for SPE pre-concentration of 90 pesticides from water—acetone extracts of fresh frxtits and vegetables with a subsequent pesticide analysis by GC-MS [285]. Only the most polar pesticides (methamidophos, acephate, and omethoate) could not be determined by this technique. Finally, a simple, fast, and sensitive method of determining a mycotoxine potuline (a metabolite of many moulds Penicillium and Aspergillus) in fruits and fruit juices was developed [286]. The method includes SPE pre-concentration of the toxin on Purosep 200 and its quantification by normal-phase FIPLC and provides recoveries over 90%, with LOD five times lower than the allowed tolerance Hmit, 50 Xg/kg.
