New solvents for extracting gallic acid from chestnut shells: deep eutectic solvents

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract Chestnut (Castanea sativa Mill.) shell, a byproduct of chestnut processing, is a valuable source of phenolic compounds that have a range of industrial applications. This study investigated the optimization of gallic acid extraction from the outer shell of the chestnut using ultrasound‐assisted extraction (UAE) and deep eutectic solvents (DES).

Non‐targeted metabolite profiling reveals biochemical diversity of three East Asian mosses

open access: yesBulletin of the Korean Chemical Society, EarlyView.
Mosses are known for their bioactive composition and adaptation to environmental stresses. This study explores the metabolic diversity of three East Asian moss species, Niphotrichum japonicum, Calohypnum plumiforme, and Polytrichum formosum, using high‐resolution mass spectrometry. Lipids, particularly unsaturated fatty acids linked to cold adaptation,
