Special Issue Information

Dear Colleagues,

The analysis of natural and bioactive compounds has witnessed a remarkable transformation in recent years, owing to significant advancements in chromatographic techniques. These compounds, found in medicinal plants, phytochemicals, functional foods, and supplements, have captured the attention of researchers across various scientific disciplines. Their applications in fields as diverse as pharmaceuticals, agriculture, environmental science, and food chemistry have spurred the development of novel analytical approaches.

Chromatography has long been a cornerstone in the field of analytical chemistry, enabling the separation, identification, and quantification of a wide range of compounds. In recent years, the development of advanced chromatographic methodologies has revolutionized the analysis of natural and bioactive compounds. These compounds, which include phytochemicals, natural products, and biologically active substances, play crucial roles in various scientific fields.

In this context, the Special Issue titled "Advanced Chromatographic Methodologies for the Analysis of Natural and Bioactive Compounds" seeks to explore and celebrate these groundbreaking developments. We welcome submissions that focus on the innovative application of advanced chromatographic techniques in the analysis of natural and bioactive compounds in real matrices. The primary objective of this Special Issue is to provide a platform for researchers to present their original works in developing novel analytical methodologies using state-of-the-art chromatographic instruments. This includes but is not limited to, techniques such as UPLC (ultra-performance liquid chromatography) with high-resolution detectors, nano-liquid chromatography, capillary chromatography, and gas chromatography.

Lacquer sap has been traditionally used in coatings and artwork. Suitable types of lacquer are required to preserve and restore artifacts. Recently, unsuitable cashew nut shell liquid (CNSL) has often been mixed with lacquer sap, so it is necessary to identify the characteristics of lacquer sap by the production area. However, research is still focused on urushiol and laccol. In this study, Myanmarese lacquer sap collected from Gluta usitata, which contains thitsiol as the main component, was analyzed by HPLC to quantify thitsiol using the standards 3-(10-phenyldecyl) benzene-1,2-diol (thitsiol 16) and 3-(8Z,11Z-pentadecadienyl)-benzenediol (urushiol 15:2) as markers, and calibration curves were plotted. The coefficients of determination (R2) for thitsiol 16 and urushiol 15:2 were 0.9985 and 0.9983, respectively. In addition, a blind test was conducted to confirm that accurate quantitative analysis was possible even when Myanmarese lacquer was mixed with lacquer from another production area, which contained urushiol as the main component, and CNSL, which contained cardol, a completely different catechol. Quantitative analysis of thitsiol 16 and urushiol 15:2 in Myanmarese lacquer using HPLC can be used to evaluate the quality of lacquer sap and for more sophisticated activities such as restoration by classifying differences in lacquer sap by the production area.

Consumers in developed and Western European countries are becoming more aware of the impact of food on their health, and they demand clear, transparent, and reliable information from the food industry about the products they consume. They recognise that food safety risks are often due to the unexpected presence of contaminants throughout the food supply chain. Among these, mycotoxins produced by food-infecting fungi, endogenous toxins from certain plants and organisms, pesticides, and other drugs used excessively during farming and food production, which lead to their contamination and accumulation in foodstuffs, are the main causes of concern. In this context, the goals of this review are to provide a comprehensive overview of the presence of toxic molecules reported in foodstuffs since 2020 through the Rapid Alert System for Food and Feed (RASFF) portal and use chromatography to address this challenge. Overall, natural toxins, environmental pollutants, and food-processing contaminants are the most frequently reported toxic molecules, and liquid chromatography and gas chromatography are the most reliable approaches for their control. However, faster, simpler, and more powerful analytical procedures are necessary to cope with the growing pressures on the food chain supply. Full article
