“…A number of other less common extraction techniques have been also reported, including automated solid phase extraction, on-line solid phase extraction, use of molecularly imprinted polymers (MIPs), stir bar sorptive extraction (SBSE), solid phase microextraction (SPME) and magnetic solid phase extraction through silica supported Fe 3 O 4 nanoparticles (Moliner-Martínez et al, 2011). These techniques present various advantages, like less contamination between samples, higher sample throughput, minimized consumption of solvents and less labour work (Díaz-Cruz et al, 2003;Wu et al, 2010;Richardson and Ternes, 2011;Matamoros et al, 2012;Yao et al, 2011).…”

Emerging contaminants : a tutorial mini-review

Nowadays, the scientific community has focused and prioritised research on "emerging pollutants". The term "emerging pollutants" stands for the substances that are released in the environment for which currently no regulations are established for their environmental monitoring. Their occurrence is reported worldwide in a range of aquatic environments, such as lakes, rivers, freshwater catchments, estuaries, reservoirs and marine waters. Nevertheless, due to their large number (ranging in an order of thousands), only few of these compounds are toxicologically evaluated. Published data concerning occurrence and potential toxicological effects is limited. The contamination source of the aquatic environment is mainly the effluents from the sewage treatment plants (STPs). Reliable methods are available for residue analysis of these pollutants down to low ng L -1 levels. However, an urgent need is highlighted for the investigation (primarily in environmental media and following in biological ones) of the toxicity and transformation pathways of all emerging pollutants. The aims of this mini-review are to briefly present: (a) the major classes of emerging pollutants; (b) the reasons why these substances constitute an environmental issue; and (c) developments and applications of environmental analysis in this field.

“…Samples as biological fluids and plant extracts exhibit a phenomenon known as the matrix effect which corresponds to the influence and interference that all components of the sample in their entirety can exert in the analysis of a component or group of them [23][24][25]. The interfering…”

Objective: This study aims to develop the extraction of the marker kaempferol in the fluid extract (FE) and validate an analytical method that monitors the quality of extracts of P. pyramidalis. Methods:The P. pyramidalis leaves were collected and then were dried to milling process. The extracts were drawn up at 20% weight: Volume (w/v) by maceration, and the extraction system used was hydroethanol solution ratio at 50:50 volume: Volume (v: v). From the hydroalcoholic extract, a method of extracting the kaempferol biomarker was developed and validated by high-performance liquid chromatography coupled with diode array detector. To validate a method, the following parameters were evaluated: Specificity, selectivity, linearity, limit of quantification (LOQ) and detection (LOD), precision, accuracy, robustness, and stability. Results:The method developed proved to be efficient, as it allowed the analysis of the interferents free marker, with recovery above 90%, linear over the range 1.4-26.6 µg/mL, correlation coefficient R 2 =0.999, and LOD and LOQ 0.07 and 0.22 µg/mL, respectively, specificity, precision, accuracy, and robustness. Conclusion:The extraction methodology of the kaempferol marker was successfully developed interferents free and the validated method by HPLC-DAD represents a useful tool in the quality control of P. pyramidalis herbal medicines.

“…The pretreatment of samples is a decisive step in the development of the analytical methods of constituents in biological matrices and must guarantee the release of the analytes of the complex matrix, to be monitored by analytical signals with appropriate instrumentation [19][20][21]. Some matrices of plant´s components may behave as interferers, which impair the identification and quantification of biomarkers, in addition, these interferers may compromise the performance of chromatographic systems [18,[21][22][23].…”

Objective: The Anadenanthera colubrina (Vell.) Brennan var. cebil is a medicinal plant that has been used for the treatment of many diseases in the northeastern region of Brazil. This plant contains secondary metabolites such as quercetin, a flavonoid that is known by its antioxidant and antiinflammatory effects. The aim of this work is to propose the validation of an analytical method using high-performance liquid chromatography with diode array detector (HPLC-DAD) for the quantification of quercetin and standardization of the hydroalcoholic extract (HAE) of A. colubrina. Methods:The A. colubrina extracts were prepared by the maceration process with powdered leaves at 20% weight: volume (w/v) and a hydroalcoholic solution at 50% volume: volume (v/v) for 120 h at room temperature. After pretreatment of the hydroalcoholic extract, the quercetin marker was used for quantification and proceeded to the evaluation of validation parameters for the method using HPLC-DAD. Results:The analytical method proved to be specific. Linear over the range 1.4-26.6 µg/ml, regression analysis showed a good correlation coefficient (R2= 0.999); the limit of detection (LOD) and the limit of quantification (LOQ) were 0.27 and 0.81 μg/ml respectively. The relative standard deviation (RSD) did not exceed 2.5% for precision. The proposed method was validated with an average recovery of 92.5-97.5%. Conclusion:The method was validated using HPLC-DAD, allowing the quantification of quercetin in the standardisation process of extracts and quality control of the herbal drug containing A. colubrina Phyto complex.
