“…Pesticides may be used during cultivation of medicinal plants in order to prevent, repel, or control the effects of pests [85,86]. Inappropriate agricultural practices can lead to the accumulation of pesticides in herbal material, and extraction processes can lead to their enrichment in herbal preparations [86].…”

“…Pesticides are associated with a range of adverse pharmacological effects from acute reactions such as skin rashes and asthma attacks to chronic diseases like emphysema or cancer [87]. Pesticides can be mainly categorized into four compound classes, namely, organophosphorus pesticides, organochlorine pesticides, pyrethroid pesticides, and carbamate pesticides [85]. Because of their long persistence in the environment and the human body, organochlorine pesticides have been banned or restricted in many countries.…”

ResumoEste artigo proporciona uma visão geral da técnica de Extração em Fase Sólida Dispersiva (D-SPE) como uma importante etapa do método QuEChERS que, com um procedimento fácil e rápido, permite obter extratos mais limpos para as análises multirresíduo. A D-SPE envolve, em geral, o uso de um ou mais sorventes, juntamente com sulfato de magnésio anidro, em um tubo de centrífuga, para remover os coextrativos do extrato orgânico. Esta técnica é prática e eficiente para limpar extratos de diferentes amostras complexas, como alimentos de origem vegetal ou animal. Alguns detalhes práticos do uso de diferentes sorventes são apresentados com as principais aplicações. Palavras-chavePreparo de amostra; limpeza de extratos; sorventes. Dispersive Solid Phase Extraction in the determination of residues and contaminants in food AbstractThis paper provide an overview of the technique Dispersive Solid Phase Extraction (D-SPE) as an important step of the QuEChERS method that permit to obtain, in a easy and quick procedure, cleaned extracts for the multiresidue analysis. The D-SPE involves, in general, the use of one or more sorbent together with magnesium sulfate anhydrous in a centrifuge tube to remove the co-extractives from the organic extract. This technique is practical and efficient to clean-up extracts from different complex samples, like foods of vegetable or animal origin. Some practical details of different sorbents are presented with principal applications.

Sweetness is a traditional sensory indicator used to evaluate the quality of the popular Chinese herb Radix Astragali (RA). RA roots with strong sweetness are considered to be of good quality. However, neither a thorough analysis of the component(s) contributing to RA sweetness, nor a scientific investigation of the reliability of this indicator has been conducted to date. In this study, seven kinds of sweetness components were identified in RA and a quality evaluation method based on these components was established and used to characterize the quality of 48 RA samples. The sweetness evaluation method of RA was first built based on the sweetness components, and a comprehensive evaluation index commonly used in quality control of RA was also derived, which was based on the contents of four indicators (astragaloside IV, calycosin glucoside, polysaccharides and extracts). After evaluating the correlation of these indexes the results showed that the level of sweetness exhibited a strong positive correlation with the proposed comprehensive index. Our results indicate that sweetness is one of the most important quality attributes of RA and thus provide a scientific basis for the utility of the sweetness indicator in quality assessment of this Chinese herb.
