New Analytical Methods in Plant Active Components Analysis

Topic Information

Dear Colleagues,

Plants are well known as one of the greatest resources of active components that are usually used for the development of new drugs, functional foods, and dietary supplements. The discovery of new biologically active compounds from natural sources seems to be the main objective of many pharmaceuticals and food companies. Current research trends clearly indicate that natural active components will be among the most significant sources of new drugs in the future. Due to the complexity of plant active chemical constituents, the development of new robust, efficient, sensitive, and cost-effective methods to improve separation, extraction, and purification of these compounds is of great interest, which may provide the necessary basis for further study of the bioactivity, structure–activity relationships, metabolisms in vivo, structural modification, and synthesis of active compounds. This topic, “New Analytical Methods in Plant Active Component Analysis”, covers a selection of research articles, communications, or reviews that explore plant active compounds’ isolation and structural determination via analytical methods, including chromatography, mass spectrometry, spectroscopy, and electroanalysis. We are particularly interested in articles describing new analytical strategies for determining active compounds in plants, with selected applications linked to current trends in food chemistry, the environment, biology, and pharmaceuticals. Novel applications and the optimization of existing analytical methods are also welcome.

For oenological products, most of the intrinsic and extrinsic drivers of perceived quality are associated with specific aromatic profiles. Aromatic diversity has been recognized as a central element in perceived quality as it is able to transmit the complex interactions between grape variety, geographical characteristics, and viticultural and winemaking practices, including the fermentative process. A comprehensive characterization of flavour compounds by headspace solid-phase microextraction (HS-SPME) and gas chromatography coupled to mass spectrometric analysis is often needed in order to ascertain the quality of wine. HS-SPME requires a proper optimization that can be achieved through an adequate experimental design. Here, a HS-SPME/GC-MS based method was developed to investigate the volatile compounds of wine samples obtained by laboratory-scale fermentations. This was performed by inoculating a commercial Saccharomyces cerevisiae strain, which is used both as single starter and as mixed starter, with an indigenous Hanseniaspora osmophila strain. The experimental conditions of HS-SPME (extraction temperature and time) were optimized by applying a face-centred composite experimental design. Up to 95% of the total variance was explained by the proposed model. The optimized method allowed us to confirm the usefulness of combining the inoculation of grapes with selected yeast strains in co-culture situations in order to improve the wine bouquet.

Picloram and 2,4-D are systemic herbicides used to control a wide range of broad-leaved weeds and post-emergence annual and perennial broad-leaved weeds, respectively. The use of plant protection products containing Picloram and 2,4-D necessitates the development of analytical methods, useful for the laboratories focused on control, for monitoring. In this study, we designed and validated an analytical method for the rapid determination of picloram and 2,4-D by HPLC-DAD. The method involves the extraction of the substances by sonication of the sample with methanol, followed by dilution in acetonitrile, and direct injection on a liquid chromatography system, based on the use of a Gemini C18 column. We used an isocratic mobile elution consisting of acetonitrile and water acidified 1% with H₃PO₄ (50:50, v/v). We validated the proposed method, which demonstrated linearity within the concentration range of 0.01–0.028 mg/mL for picloram and 2,4-D, with a correlation coefficient (R²) of 0.9993 for picloram and 0.9999 for 2,4-D. We considered precision, repeatability and selectivity in the validation. The repeatability of the method expressed as percent of relative standard deviation (%RSD) was lower than 1% for both substances. The proposed method is suitable for the simultaneous determination of picloram and 2,4-D in pesticide formulations. Full article
