Agarwal, Charu published the artcileLow-frequency, green sonoextraction of antioxidants from tree barks of Hungarian woodlands for potential food applications, Quality Control of 30931-67-0, the publication is Chemical Engineering and Processing (2021), 108221, database is CAplus.

The present work evaluates and compares the antioxidant capacities of bioactive constituents in the barks of ten common wood species from Hungary (Quercus rubra, Prunus serotina, Quercus robur, Betula pendula, Fraxinus excelsior, Robinia pseudoacacia, Carpinus betulus, Picea abies, Alnus glutinosa, Pinus sylvestris). Low-frequency ultrasound was used for intensification of extraction from the bark to obtain extracts rich in polyphenolic antioxidants with potential applications in the food industry. The extractions were carried out in different aqueous organic solvents- ethanol 80% and acetone 80% at optimized conditions. The overall antioxidant capacity of the extracts was estimated by the combined evaluation of Folin-Ciocalteu total phenol content (TPC), 2,2-diphenyl-1-picrylhydrazyl (DPPH), 2,2′-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) and ferric reducing ability of plasma (FRAP) assays using a scoring system. Aqueous ethanol had better extraction efficiency than aqueous acetone as a solvent medium. Of all the investigated species, Quercus robur showed the maximum antioxidant capacity with TPC of 105.88 ± 17.75 mg GAE/g dw, DPPH (IC50) of 1.90 ± 0.10μg/mL, ABTS of 437.09 ± 36.22 mg TE/g dw and FRAP of 102.62 ± 8.69 mg AAE/g dw. The polyphenolic characterization of Quercus robur, Robinia pseudoacacia and Fraxinus excelsior was done by liquid chromatog./tandem mass spectrometry.
