The combination of chemometric and green metric tools adds up to synergistic effects at method development, being highly compatible with green analytical chemistry (GAC). In the present study, both strategies were applied for the development of an ultrasound-assisted extraction mediated by Natural Deep Eutectic Solvent (UA-NADES). The Box-Behnken Design combined with multiple responses and desirability functions allowed the effective optimization of the proposed extractive methodology using an alternative green solvent. Considering the obtained results, a green UA-NADES extraction and chromatographic determination of phenolic compounds in Lactuca sativa samples were developed. Finally, the recent Analytical GREEnness metric approach was applied, and scores were compared with recent miniaturized approaches for the extraction/determination of phenolic compounds in lettuce. The results of the AGREE analysis highlight the greenness of the proposed methodology.

Ginkgolic acids (GAs) are distinctive secondary metabolites of () primarily found in its leaves and seeds, with the highest concentration located in the exotesta. GAs are classified as long-chain phenolic compounds, and exhibit structural similarities to lignoceric acid. Their structural diversity arises from variations in the length of side chains and their number of double bonds, resulting in six distinct forms within extracts (GBE).

This study investigated the production and application of lignocellulosic wood vinegar and tar as organic pesticides to combat bacterial canker disease in trees, caused by pathogenic bacteria. Lignocellulosic wood vinegar and tar were produced from various lignocellulosic wastes through pyrolysis at different temperatures, with sawdust at 300 °C, 350 °C, and 400 °C yielding the highest quantity and quality of vinegar. Chemical analysis revealed that the lignocellulosic vinegar contained significant concentrations of acetic acid, methanol, and phenolic compounds, all known for their strong antimicrobial properties.

The mushroom Pleurotus ostreatus is widely produced in Brazil and its stipes are discarded before commercialization. In the present study, this agricultural fungal waste (mushroom stipes), was analyzed by preparing an aqueous extract and obtaining the polysaccharides by ethanol precipitation (POS-extract). The fraction presented 37 % of carbohydrates and small amounts of proteins and phenolic compounds.
