| description | ABSTRACT
Carbaryl (1-naphthyl-N-methylcarbamate) and carbofuran (2,3-dihydro-2,2-dimethyl-7-benzofuranol-Nmethylcarbamate)
are very important N-methylcarbamatepesticides due to their high insecticide and nematocide
effects, and widely used in vegetables plantations. The increasing use of carbamate pesticides poses a risk to
human and environment. Thus, it is necessary to quantify their residue amount in food and vegetables to prevent
harmful effect on animals, human and. environment. This work was aimed to study of carbaryl and carbofuran
analysis from fortified cabbage (Brassicaoleracea) by liquid-liquid extraction, clean-up using SPE, followed by HPLC
detection. Result of the work showed that detection of carbaryl using spectrophotometerdetector at wavelength of
220 nm was better than at 230 and 280 nm, respectively. When the carbamates were extracted from cabbage using
methanol, followed by liquid-liquid extraction using dichloromethane, cleaned-up with SPE-C18 and eluted by
acetonitrile, the recovery was 96.8%. The detection by HPLC involved 4.6 x 25 mm, 5 pm C18 column,
spectrophotometer detector at wav~/ength of 220 nm, and isocratic mobile phase at ratio of 35:65 of
acetonitrile:aquabidestgave a good separationbetween co-extractedcompoundsand the carbamates.
