19714988 de Carvalho PH, Prata Vde M, Alves PB, Navickiene S: Determination of six pesticides in the medicinal herb Cordia salicifolia by matrix solid-phase dispersion and gas chromatography/mass spectrometry. J AOAC Int. 2009 Jul-Aug;92(4):1184-9.

A simple and effective extraction method based on matrix solid-phase dispersion was developed for acephate, chlorpropham, pyrimicarb, bifenthrin, tetradifon, and phosalone in leaves of the medicinal plant Cordia salicifolia, whose extracts are commercialized in Brazil as diuretic, appetite suppressant, and weight loss products.
Different parameters of the method were evaluated, such as type of solid phase (C18, alumina, silica gel, and Florisil) and the amount of solid phase and eluent (dichloromethane, ethyl acetate, chloroform, and cyclohexane).

12113343 Brito NM, Navickiene S, Polese L, Jardim EF, Abakerli RB, Ribeiro ML: Determination of pesticide residues in coconut water by liquid-liquid extraction and gas chromatography with electron-capture plus thermionic specific detection and solid-phase extraction and high-performance liquid chromatography with ultraviolet detection. J Chromatogr A. 2002 May 31;957(2):201-9.

The first procedure involves solid-phase extraction using Sep-Pak Vac C18 disposable cartridges with methanol for elution.
The other procedure is based on liquid-liquid extraction with hexane-dichloromethane (1:1, v/v), followed by gas chromatographic analysis with effluent splitting to electron-capture detection for determination of endosulfan, captan, tetradifon and trichlorfon and thermionic specific detection for determination of malathion, parathion-methyl and monocrotophos.

11324596 Garcia-Repetto R, Gimenez MP, Repetto M: New method for determination of ten pesticides in human blood. J AOAC Int. 2001 Mar-Apr;84(2):342-9.

The pesticides studied, which have appeared frequently in actual cases, were endosulfan, lindane, parathion, ethyl-azinphos, diazinon, malathion, alachlor, tetradifon, fenthion and dicofol (o-p' and p-p' isomers).
The extraction is performed by solid-phase extraction, with C18 cartridges and 2 internal standards, perthane and triphenylphosphate.
