“…The liquid-liquid extraction was used to clean the targeted material analysis in matrix such as soil, water and plant (Sabik and Jeannot, 1998;Wang et al, 2008;Pirsaheb et al, 2013). The method was applied to clean-up for AMS, DMDS, AS, PS, DADS, and DATS analysis.…”

BACKGROUND: Garlic (Allium sativum) extract has been allowed as commercial biopesticide material for pesticidal activity in the Environmentally-friendly Agriculture Promotion Act. Nine commercial biopesticides containing A. sativum extract have been marketed in Korea. However, the analytical method of the active substances in these materials has not been studied. METHODS AND RESULTS: Cartridge clean-up method for the determination of dimethyl disulfide(DMDS), diallyl disulfide(DADS), and diallyl trisulfide(DATS) in biopesticides containing A. sativum extract was developed and validated by gas chromatography(GC). The clean-up method was optimized using hydrophilic lipophilic balance (HLB) solid phase extraction(SPE) cartridges for the bioactive sulfides in biopesticides containing A. sativum extract, and the eluate was analyzed to quantify the DMDS, DADS, and DATS using the GC. The developed method was validated, and the LOQ and recovery rates of DMDS,

The pneumatic nebulization gas-solid microextraction device fascinating us is because it directly atomized organic samples to cross a solid-phase microextraction (SPME) cartridge without any pretreatment. In this work, both the spray chamber and SPME column of the extraction device were heated. We found that this would significantly improve the extraction efficiency of this method. Then, this method was used to detect seven triazine herbicides (atraton, desmetryn, atrazine, terbumeton, terbuthylazine, terbutryn, and dipropetryn) in drinking alcohol samples. The experimental results indicated that this extraction procedure could conveniently, efficiently and accurately concentrate any triazine herbicides from drinking alcohol samples. The limits of detection (LODs) were from 0.08 to 0.23 μg L -1 , the limits of quantification (LOQs) were from 0.27 to 0.78 μg L -1 . We used this method to detect triazine herbicides in five white spirit samples. Four concentrations were chosen (5, 25, 50 and 100 μg L -1 ) as the amounts of spikes to investigate the recovery and precision of the present PN-GSME method. The recoveries ranged from 95.91 to 106.67%. The relative standard deviations were not more than 6.51%. Also this method matches the requirement of the maximum residue limits of the European Union.
