Cherry tree branches ( var Rosaceae) are agricultural by-products that are often neglected, yet they are rich in phenolic compounds and highly appreciated for their numerous biological activities. Extracts of cherry tree branches were evaluated for their use in cosmetics, particularly for their antioxidant, anti-tyrosinase, and antimicrobial activities. Samples were obtained by accelerated solvent extraction (ASE) at different ethanol percentages and different temperatures. Fourteen phenolic compounds were identified in the extracts by mass spectrometry. Three major compounds were identified (catechin, genistin, and prunin) representing 84 wt% of the total phenolic compounds. Optimal operating conditions maximizing the content of phenolic compounds were determined using a one factor at a time (OFAT) approach (70% aqueous ethanol, 70 °C). The extract obtained under these conditions also showed the highest antioxidant and anti-tyrosinase activities, certainly due to a high catechin content. Although the antimicrobial activities of extracts are less versatile than those of synthetic molecules, they are nonetheless interesting. According to these results, the extracts of cherry tree branches could be used in cosmetics for their interesting properties.

This study aimed to explore the effect of anthocyanin-rich black sugarcane on milk production, plasma antioxidant capacity, and the storage period DPPH scavenging capacity of milk in lactating dairy cows. Sixteen lactating dairy cows were stratified and randomly assigned into two balanced dietary groups, namely Anthocyanin-rich black sugarcane (AS), and Napier grass (NG). The AS group demonstrated a significant decrease (p < 0.

4-Phenol oxidases are proposed to be involved in the utilization of lignin-derived aromatic compounds. While enzymes with selectivity towards 4-hydroxyphenyl and guaiacyl motifs are well described, we identified the first syringyl-specific oxidase from Streptomyces cavernae (Sc4ASO) only very recently. Here, in-depth studies were conducted to unravel the molecular origins of the outstanding selectivity of Sc4ASO.

Walnut husk extract (WHE) and pomegranate peel extract (PPE) were produced through ultrasound-assisted extraction. Total phenol, flavonoid and tannin contents (TPC, TFC and TTC), antioxidant and antimicrobial activities were determined. The best extracts were used for production of alginate (Alg) and chitosan (CS)-coated nanoemulsions containing WHE (NWHE) or PPE (NPPE).
