Major Phytochemicals: Recent Advances in Health Benefits and Extraction Method

Molecules, Journal Year: 2023, Volume and Issue: 28(2), P. 887 - 887

Published: Jan. 16, 2023

Recent scientific studies have established a relationship between the consumption of phytochemicals such as carotenoids, polyphenols, isoprenoids, phytosterols, saponins, dietary fibers, polysaccharides, etc., with health benefits prevention diabetes, obesity, cancer, cardiovascular diseases, etc. This has led to popularization phytochemicals. Nowadays, foods containing constituent (functional foods) and concentrated form (nutraceuticals) are used preventive measure or cure for many diseases. The these depend on their purity structural stability. yield, purity, stability extracted matrix in which phytochemical is present, method extraction, solvent used, temperature, time extraction.

Sustainable production of benzene from lignin

Nature Communications, Journal Year: 2021, Volume and Issue: 12(1)

Published: July 26, 2021

Abstract Benzene is a widely used commodity chemical, which currently produced from fossil resources. Lignin, waste lignocellulosic biomass industry, the most abundant renewable source of benzene ring in nature. Efficient production lignin, requires total transformation C sp2 -C sp3 /C -O into C-H bonds without side hydrogenation, great importance, but has not been realized. Here, we report that high-silica HY zeolite supported RuW alloy catalyst enables situ refining exclusively to via coupling Bronsted acid catalyzed on local structure lignin molecule and hydrogenolysis using locally abstracted hydrogen molecule, affording yield 18.8% weight basis water system. The reaction mechanism elucidated detail by combination control experiments density functional theory calculations. high-performance protocol can be readily scaled up produce 8.5 g product 50.0 any saturation byproducts. This work opens way as feedstock efficiently.

Structural materials with afterglow room temperature phosphorescence activated by lignin oxidation

Nature Communications, Journal Year: 2022, Volume and Issue: 13(1)

Published: Sept. 20, 2022

Abstract Sustainable afterglow room temperature phosphorescence (RTP) materials, especially RTP structural are crucial but remain difficult to achieve. Here, an oxidation strategy is developed convert lignin materials with a lifetime of ~ 408 ms. Specifically, oxidized give aromatic chromophores and fatty acids using H 2 O . The locked by acid-based matrix hydrogen bonds, triggering enhanced spin orbit coupling long emission. More interestingly, motivated this discovery, auto fabrication line built wood (natural materials) emission (RTP wood) via in situ naturally-occurring located the cell walls (OL). as-prepared exhibits great potential for construction sustainable furniture. With research we provide new promote sustainability materials.

Functional surfaces, films, and coatings with lignin – a critical review

RSC Advances, Journal Year: 2023, Volume and Issue: 13(18), P. 12529 - 12553

Published: Jan. 1, 2023

Lignin is the most abundant polyaromatic biopolymer. Due to its rich and versatile chemistry, many applications have been proposed, which include formulation of functional coatings films. In addition replacing fossil-based polymers, lignin biopolymer can be part new material solutions. Functionalities may added, such as UV-blocking, oxygen scavenging, antimicrobial, barrier properties, draw on lignin's intrinsic unique features. As a result, various including polymer coatings, adsorbents, paper-sizing additives, wood veneers, food packaging, biomaterials, fertilizers, corrosion inhibitors, antifouling membranes. Today, technical produced in large volumes pulp paper industry, whereas even more diverse products are prospected available from future biorefineries. Developing for hence paramount - both technological economic point view.
