“…Therefore, after carefully considering the recoveries and co-eluted matrix components, 10 mg of CCG was used. Notably, in normal MSPD processes, about 0.5 g of sample was required and the ratio of sorbent to sample ranged from 1:1 to 4:1 [24]. However, in GA-MSPD, the ratio of CCG to sample was 1:10, which was much lower than those in normal MSPD applications, mainly due to the high surface area and unique morphology of CCG.…”

“…This also represents the first attempt to use graphene as sorbent in MSPD. MSPD allows simultaneous sample dispersion, extraction and cleanup in a single step, thus eliminating most of the complications of classical liquid-liquid extraction or solid-phase extraction (SPE) when handling with solid samples [23,24]. The solid sample was mixed and ground with CCG powder to produce an apparent homogeneous blend.…”

In this work, we developed a novel graphene-assisted matrix solid-phase dispersion (GA-MSPD) method for extraction of polybrominated diphenyl ethers (PBDEs) and their methoxylated (MeO-) and hydroxylated (OH-) analogs from environmental samples. We found that grinding the solid sample with chemically converted graphene (CCG) powder yielded a tight contact and sufficient dispersion of the sample matrix due to the large surface area and flexible nanosheet morphology of CCG. The resultant blend was eluted using a two-step elution strategy: PBDEs and MeO-PBDEs were eluted firstly by hexane/dichloromethane and analyzed by GC-ECD, and then OH-PBDEs were eluted by acetone and determined by LC-ESI-MS/MS. The GA-MSPD conditions were optimized in detail. Better recoveries were obtained with GA-MSPD than with other sorbents (C18 silica, Florisil and carbon nanotubes) and other extraction techniques (Soxhlet and accelerated solvent extraction). Other advantages of GA-MSPD, including reduced consumption of sorbent and solvent, good selectivity and short extraction time, were also demonstrated. In analysis of soil samples, the method detection limits of five PBDEs, ten MeO-PBDEs and ten OH-PBDEs were in the range of 5. 9-28.7, 14.3-46.6, and 5.3-212.6 pg g −1 dry weight, respectively. The proposed method was successfully applied to the extraction of PBDEs, MeO-PBDEs and OH-PBDEs from different kinds of spiked environmental samples, including soil, tree bark and fish.

“…12 The use of MSPD for pesticide recovery depends on the solubility of the pesticide in the eluting solvent, as well as the interactions between the matrix components, sorbent and eluent. 13 Due to the lack of literature reports concerning the use of MSPD as an extraction technique for pesticides belonging to different chemical classes from medicinal plants (different plants and herbs exhibit different capabilities in retaining pesticide residues), this paper presents an MSPD method for determination of residues of pesticides in sambacaitá. So, the present research considered seven different chemical classes, namely anilinopyrimidine (pyrimethanil), triazine (ametryn), sulfonamide (dichlofluanid), triazine (tetraconazole), dinitroaniline (flumetralin), strobilurin (kresoxim-methyl) and triazole (tebuconazole), with analysis by gas chromatography-mass spectrometry (GC-MS).…”

Um método baseado na técnica de dispersão da matriz em fase sólida foi desenvolvido para determinar resíduos de ametrina, tetraconazol, flumetralina, tebuconazol, pirimetanil, diclofuanida e cresoxim-metílico na planta medicinal desidratada Hyptis pectinata (sambacaitá) por cromatografia a gás acoplada a espectrometria de massas. Diferentes parâmetros foram avaliados, tais como: tipo (C 18 , alumina neutra, sílica gel e Florisil) e quantidades de sorvente e solvente de eluição (diclorometano, acetato de etila e diclorometano:acetato de etila (1:1, v/v)), sendo que o mais adequado foi o procedimento com 0,5 g de planta medicinal, 0,5 g de C 18 como sorvente e diclorometano (20 mL) como solvente de eluição. O método foi validado com amostras de planta medicinal fortificadas com agrotóxicos em diferentes níveis de concentração (0,05-1,0 μg g -1 ). Recuperações médias (n = 4) variaram de 83 a 127%, com coeficientes de variação entre 4 e 15%. Os limites de detecção (LOD) variaram entre 0,02 e 0,07 μg g -1 , enquanto que os limites de quantificação (LOQ), entre 0,05 e 0,1 μg g -1 .A method was developed using matrix solid-phase dispersion (MSPD), together with gas chromatography coupled to mass spectrometry (GC-MS) for determination of ametryn, tetraconazole, flumetralin, tebuconazole, pyrimethanil, dichlofluanid and kresoxim-methyl in dehydrated Hyptis pectinata (sambacaitá) medicinal plant material. The evaluated parameters included the type and amount of sorbent (C 18 , neutral alumina, silica gel and Florisil) and the nature of the eluent (dichloromethane, ethyl acetate and dichloromethane:ethyl acetate (1:1, v/v)). The best results were obtained using 0.5 g of plant material, 0.5 g of C 18 as sorbent and dichloromethane (20 mL) as the eluting solvent. The method was validated using plant samples spiked with pesticides at different concentration levels (0.05-1.0 μg g -1 ). Average recoveries (using four replicates) ranged from 83 to 127%, with relative standard deviations between 4 and 15%. Limits of detection (LOD) and quantification (LOQ) were in the ranges 0.02-0.07 μg g -1 and 0.05-0.1 μg g -1 , respectively.

“…It is a simple and cheap preparation technique that combines sample homogenization, extraction, and the purification of the analyzed compounds in one step [15][16][17]. MSPD possesses chromatographic characteristics that may selectively elute a single compound, several classes of compounds, or fractionation [11,18]. This method can eliminate many complicated steps in classical liquid-solid extraction (LSE) and/or solid-phase extraction and allows for the reduction of organic solvent consumption, exclusion of sample component degradation, and improvement of extraction efficiency and selectivity [15,[19][20][21].…”

“…The important step in sample preparation is the purification of crude extract usually by solid-phase extraction (SPE) or more rarely by liquid-liquid extraction (LLE). An attractive alternative, introduced for sample preparation of complex matrices, is matrix solidphase dispersion (MSPD) [11][12][13][14]. It is a simple and cheap preparation technique that combines sample homogenization, extraction, and the purification of the analyzed compounds in one step [15][16][17].…”

Summary. The use of matrix solid-phase dispersion (MSPD) was tested to extract some coumarins (umbelliferone, xanthotoxin, isopimpinellin, bergapten, and pimpinellin) from Pimpinella roots. The method was compared with liquid-solid extraction methods (LSE) such as accelerated solvent extraction (ASE), ultrasound-assisted extraction (USAE) and Soxhlet extraction followed by solid-phase extraction (SPE). Several methanol concentrations and temperature conditions were examined during the liquidsolid extraction techniques. The analysis was performed by high-performance liquid chromatography with diode array detector (HPLC-DAD). MSPD extracted furanocoumarins with satisfactory recoveries ranging from 91.65% to 97.55% and relative standard deviations lower than 5,0415%. The results presented in the paper reveal that MSPD is an efficient, fast, simple and easy-to-perform method suitable for the isolation of furanocoumarins from herbs.
