Insight in the Recent Application of Polyphenols From Biomass

Abstract

Biomass polyphenols are bio-active macromolecules with distinct chemical structures in a variety of biomass. In recent years, the study of biomass polyphenols and their application in food and medicine fields has become a research hotspot, which predominantly focuses on the preparation, purification, structural identifications, and measurements of biological activities. Many studies describe methodologies for extraction and application of polyphenols, but comprehensive work to review its physiological activities like drugs and health products are lacking. This paper comprehensively unlocks the bioactivities of antioxidant, antibacterial, antitumor, anticancer, neuroprotection, control of blood sugar, regulation of blood fat, and promotion of gastrointestinal health functions of polyphenols from different biomass sources. This review will serve as an illuminating resource for the global scientific community, especially for those who are actively working to promote the advances of the polyphenols research field.

Protective Effects of Lignin-Carbohydrate Complexes from Wheat Stalk against Bisphenol a Neurotoxicity in Zebrafish via Oxidative Stress

“…Importantly, both LCC preparations exhibited potent neuroprotective effects under BPA-induced oxidative stress in zebrafish. The antioxidant activity of LCC-WS-A and LCC-WS-B may be attributed to their lignin, carbohydrate, and polyphenol components, all of which exhibit free radical scavenging activity [14,15]. Notably, however, the antioxidant activity of LCC-WS-A, which contained more carbohydrates, was stronger than that of LCC-WS-B, which contained more lignin.…”

“…In addition, various natural antioxidants derived from plants are being used as the protective substances to minimize the neurotoxic effects of BPA [8,9]. LCCs contain numerous bioactive substances such as lignin, carbohydrates, and polyphenols, which possess antioxidant activity against free radicals in vitro and ROS in vivo [14,15]. However, few previous studies have evaluated the neuroprotective effects of LCCs against BPA-induced oxidative stress, particularly in an in vivo zebrafish model.…”

“…In plant cell wall, lignin and carbohydrates (mainly hemicellulose) are covalently linked to form the lignin-carbohydrate complexes (LCCs). Owing to the presence of both lignin and carbohydrates, LCCs possess antioxidant activity derived from lignin as well as high compatibility and adhesiveness to the cell because of the biological interaction between polysaccharides and cellular surface [14,15]. In this context, Dong et al (2020) [15] reported that the LCCs extracted from various biomass materials exhibited excellent antioxidant activity against reactive oxygen species (ROS) both in vitro and in vivo.…”

Recent Technologies for the Extraction and Separation of Polyphenols in Different Plants: A Review

“…For polyphenol, it possesses biologically active substances having an antioxidant activity, which has been regarded as the "seventh type nutrient" for health [3]. Since polyphenol has a variety of biological activities such as antioxidation, antibacterial, anti-inflammatory, anti-tumor, it has been widely used in preventing oral infections, hypophysis sugar, lowering blood pressure, neuroprotection and, prevention of cardiovascular diseases [4][5][6]. In addition, polyphenol also plays an extremely important role in the growth of fruits and vegetables, such as plant defense, mediated growth, antioxidant activity, removal of free radicals, and signaling [7].…”

Preparation and Application in Water Treatment of Magnetic Biochar

“…In this era of rapid development of the industry, people’s needs are constantly increasing to ensure the conditions of cost control to improve the profits of the industry ( Yan et al, 2021 ; Pei et al, 2020a ; Dai et al, 2020 ; Li X. et al, 2019 ; Si et al, 2009 ; Yang et al, 2019 ; Chen et al, 2020a ; Liu et al, 2020a ). Agricultural waste has received extensive attention due to its wide application and availability ( Si et al, 2013 ; Dai L. et al, 2019 ; Du et al, 2019 ; Pei et al, 2020b ; Liu et al, 2021c ; Liu.…”
