Development of a matrix solid-phase dispersion-sonication extraction method for the determination of fungicides residues in ginseng extract

Pesticide Residues in Natural Products with Pharmaceutical Use: Occurrence, Analytical Advances and Perspectives

“…Other authors have determined acephate, chlorpropham, pyrimicarb, bifenthrin, tetradifon and phosalone residues in Cordia salicifolia leaves by using neutral alumina and peat as dispersant phases plus Na 2 SO 4 and C 18 co-columns and eluting with cyclohexane:CH 2 Cl 2 and GC-MS determination (de Carvalho et al, 2009a, de Carvalho et al, 2010. In addition, Qi (2010) proposed sonicated MSPD approach on Florisil sorbent and EtAC:hexane (7:3) elution to determine pentachloronitrobencene, pentachloroaniline, methylpentachlorophenyl sulphide and procymidone in Ginseng extracts by GC-ECD. On the other hand, Pérez et al, (2010) reported the determination of a variety of OCs, OPs and pyrethoids in lanolin using MSPD on C 18 plus alumina co-column with elution performed by MeCN:n-hexane saturated and further GC-ECD/FPD determination.…”

Rapid and sensitive analysis of nine fungicide residues in chrysanthemum by matrix extraction-vortex-assisted dispersive liquid–liquid microextraction

“…In these studies, most concerns focused on organochlorine and pyrethroid pesticides [1][2][3][4]. Additionally, the analytical methods for determining pesticide residues in CHM matrices are limited, including modified QuEChERS methods [5,6], treatment with sulfuric acid [3], and matrix solid-phase dispersive extraction [7]. Monitoring of a wide range of pesticide residues in CHMs can be an important task in public health safety and international trade.…”

Miniaturized matrix solid‐phase dispersion combined with ultrasound‐assisted dispersive liquid–liquid microextraction for the determination of three pyrethroids in soil

“…It combines the sampling, extraction and cleanup into a single step, which eliminates the complications of LLE and SPE for solid and semi-solid samples [21,22]. At present, MSPD has been successfully applied to the extraction of a wide range of drugs, pesticides, naturally occurring constituents and other compounds from a wide variety of complex samples [23][24][25][26][27][28]. However, the common sorbents (C 18 , C 8 , silica gel, florisil, etc.)…”
