A review of the pharmacological applications lignins provides evidence their protective role against development different diseases. In many cases, effects could be explained by antioxidant capacity. Here, we present a systematic literature from period 2010–2016 which information concerning new derived recent research. The most promising findings are reported, including methodologies employed and results obtained with or derivatives may improve human health. We highlight potential in treatment obesity, diabetes, thrombosis, viral infections cancer. Moreover, report both that can used preparation nanoparticles to deliver drugs also use photoprotection.

Lignin from Micro- to Nanosize: Production Methods

International Journal of Molecular Sciences, Journal Year: 2017, Volume and Issue: 18(6), P. 1244 - 1244

Published: June 10, 2017

Lignin is the second most abundant biopolymer after cellulose. It has long been obtained as a by-product of cellulose production in pulp and paper production, but had rather low added-value applications. A changing market emergence biorefinery projects should generate vast amounts lignin with potential value addition. Nanomaterials offer unique properties preparation nanoparticles other nanostructures therefore gained interest promising technique to obtain value-added products. Due lignin’s high structural chemical heterogeneity, methods must be adapted these different types. This review focuses on ability formation cope huge variety types points out which particle characteristics can achieved by method. The current research’s main focus pH solvent-shifting where latter yield solid hollow particles. Solvent shifting also showed capability solvents antisolvents, respectively. However, process conditions have every type reduction solvent demand or integration chain focused.

Micro- and nanosize lignin has recently gained interest due to improved properties compared standard available today. As the second most abundant biopolymer after cellulose, is readily but used for rather low-value applications. This review focuses on application of micro- nanostructured in final products or processes that all show potential high added value. The fields are ranging from improvement mechanical polymer nanocomposites, bactericidal antioxidant impregnations hollow drug carriers hydrophobic hydrophilic substances. Also, a carbonization nanostructures can lead high-value applications such as use supercapacitors energy storage. product depend surface nanomaterial and, therefore, factors like source, extraction method, production/precipitation methods, discussed this review.

ACS Sustainable Chemistry & Engineering, Journal Year: 2019, Volume and Issue: 7(12), P. 10248 - 10256

Published: May 23, 2019

A detailed investigation of choline chloride-lactic acid (ChCl-LA)-based deep eutectic solvent (DES) extraction lignin nanoparticles from herbaceous biomass (wheat straw) was conducted. It found that DES can extract high purity (up to 94.8%) with a yield 81.5% air-dried samples and 85.9% oven-dried samples) wheat straw. The cleavages ether bonds in lignin, as well the linkages between hemicelluloses during treatments at different conditions, were analyzed. effects reaction time, treatment temperature water content straw on yield, purity, chemical structure determined. affect hydrogen bond interaction DES, which key factor influencing properties separated lignin. extracted by consists well-dispersed narrow size distribution peaking 70–90 nm. mechanism ChCl-LA-based depolymerization is discussed.
