1.Acid-base reaction-based dispersive liquid-liquid microextraction method for extraction of three classes of pesticides from fruit juice samples.
Farajzadeh MA1, Afshar Mogaddam MR2. J Chromatogr A. 2016 Jan 29;1431:8-16. doi: 10.1016/j.chroma.2015.12.059. Epub 2015 Dec 24.
A sample preparation method involving acid-base reaction-based dispersive liquid-liquid microextraction coupled with gas chromatography using nitrogen-phosphorous detection has been developed for the analysis of three classes of pesticides in juice samples. In this method, a basic organic solvent (p-chloroaniline) is used as an extraction solvent. It is dissolved in acidified deionized water and then injected into an alkaline aqueous sample solution. After injection, an acid-base reaction occurs and deprotonation of the organic solvent leads to formation of tiny droplets of the extractant and subsequent extraction of the analytes from sample solution. Under the optimum extraction conditions, the method showed low limits of detection and quantification in the range of 0.05-0.43ngmL(-1) and 0.17-1.43ngmL(-1), respectively. Extraction recoveries and enrichment factors were between 39.2 and 84.1% and between 548 and 1178, respectively. Relative standard deviations of less than 8.
2.Pesticides in persimmons, jujubes and soil from China: Residue levels, risk assessment and relationship between fruits and soils.

Extreme and uncontrolled usage of pesticides produces a number of problems for vegetation and human health. In this study, the existence of organophosphates (OPs), organochlorines (OCs), pyrethroids (PYs) and fungicides (FUs) were investigated in persimmons/jujubes and their planted soils, which were collected from China. One OP (dimethoate), three OCs (DDT, quintozene and aldrin), six PYs (bifenthrin, fenpropathrin, cyhalothrin, cypermethrin, fenvalerate and deltamethrin) and two FUs (triadimefon and buprofezin) were found in 36.4% of persimmons and 70.8% of jujubes, with concentrations from 1.0 μg/kg to 2945.0 μg/kg. The most frequently detected pesticides in the two fruits were fenpropathrin in persimmons and cypermethrin in jujubes, with the detection frequencies of 30.0% and 22.7%, respectively. The residues of 4.5% (persimmon) and 25.0% (jujube) of samples were higher than the maximum residue limits (MRLs) of China. Compared with the fruits, more types of pesticides and higher residues were observed in their planted soils.
3.Simultaneous enantioselective determination of triadimefon and its metabolite triadimenol in edible vegetable oil by gel permeation chromatography and ultraperformance convergence chromatography/tandem mass spectrometry.
Yao Z1,2,3,4,5, Li X6, Miao Y5, Lin M4, Xu M1,2,3, Wang Q1,2,3, Zhang H7,8,9. Anal Bioanal Chem. 2015 Nov;407(29):8849-59. doi: 10.1007/s00216-015-9046-y. Epub 2015 Sep 28.
A novel, sensitive, and efficient enantioselective method for the determination of triadimefon and its metabolite triadimenol in edible vegetable oil, was developed by gel permeation chromatography and ultraperformance convergence chromatography/tandem triple quadrupole mass spectrometry. After the vegetable oil samples were prepared using gel permeation chromatography, the eluent was collected, evaporated, and dried with nitrogen gas. The residue was redissolved by adding methanol up to a final volume of 1 mL. The analytes of six enantiomers were analyzed on Chiralpak IA-3 column (150 × 4.6 mm) using compressed liquid CO2-mixed 14 % co-solvents, comprising methanol/acetonitrile/isopropanol = 20/20/60 (v/v/v) in the mobile phase at 30 °C, and the total separation time was less than 4 min at a flow rate of 2 mL/min. Quantification was achieved using matrix-matched standard calibration curves. The overall mean recoveries for six enantiomers from vegetable oil were 90.
4.Plant growth regulators induced urease activity in Cucurbita pepo L. cotyledons.
El Shora HM1, Ali AS2. Acta Biol Hung. 2016 Mar;67(1):53-63. doi: 10.1556/018.67.2016.1.4.
This study is aimed to investigate the activity of urease (EC, urea amidohydrolase) that catalyzes the hydrolysis of urea in 5-day-old Cucurbita pepo cotyledons subjected to various concentrations of different growth regulators. The treatment of C. pepo cotyledons with different concentrations (100-600 μmol) of different auxins [indole-3-acetic acid (IAA), indole butyric acid (IBA), indole propionic acid (IPA) and naphthalene acetic acid (NAA)]; or with different concentrations (100-300 μmol) of different cytokinins [kinetin, zeatin and benzyladenine (6-BA)] resulted in a significant increase of urease activity, compared to control. The optimal effects were recorded for each of 500 μmol of IAA and 300 μmol of zeatin treatments. A gradual increase in urease activity was detected in cotyledons treated with various concentrations (0.2-1.0 mM) of 28-homobrassinolide (HBL), in relative to control. A substantial increase in urease activity was observed in cotyledons subjected to different concentrations of triazole (10-60 mg L(-1)), containing either triadimefon (TDM) or hexaconazole (HEX), compared to control.
