The particular characteristics of growth and development of mushrooms in nature result in the accumulation of a variety of secondary metabolites such as phenolic compounds, terpenes and steroids and essential cell wall components such as polysaccharides, b-glucans and proteins, several of them with biological activities. The present article outlines and discusses the available information about the protective effects of mushroom extracts against liver damage induced by exogenous compounds. Among mushrooms, Ganoderma lucidum is indubitably the most widely studied species. In this review, however, emphasis was given to studies using other mushrooms, especially those presenting efforts of attributing hepatoprotective activities to specific chemical components usually present in the mushroom extracts.

Agri-food residues have accumulated globally at unprecedented scales, generating environmental pressures and resource inefficiencies, a core problem addressed in this review, while simultaneously representing rich, underutilized reservoirs of health-promoting phytochemicals. This review synthesizes recent advances (2016–2025) in the green extraction, characterization, and biological validation of phytochemicals from plant-based residues, including polyphenols, flavonoids, carotenoids, alkaloids, and dietary fibers from key sources such as grape pomace, citrus peels, coffee silverskin, pomegranate peel, cereal brans, and tropical fruit by-products. Emphasis is placed on sustainable extraction methods: ultrasound-assisted extraction (UAE), microwave-assisted extraction (MAE), pressurized liquid extraction (PLE), supercritical CO₂ extraction (SFE), and natural deep eutectic solvents (NADES), which enable efficient recovery while minimizing environmental impact. In vitro, in vivo, and clinical studies demonstrate that residue-derived compounds exert antioxidant, anti-inflammatory, metabolic-regulating, and prebiotic effects, contributing to health in general and gut microbiota modulation. Integrating these bioactives into functional foods and nutraceuticals supports sustainable nutrition and circular bioeconomy goals by reducing food waste and promoting health-oriented valorization. Regulatory advances, including approvals from the European Food Safety Authority (EFSA) and the U.S. Food and Drug Administration (FDA) for ingredients such as olive phenolics, citrus flavanones, and coffee cascara, further illustrate increasing translational readiness. The convergence of green chemistry, biorefinery design, and nutritional science positions agri-food residues as pivotal resources for future health-promoting and environmentally responsible diets. Remaining challenges include scaling cost-effective green processes, harmonizing life cycle assessment protocols, expanding toxicological datasets, and conducting longer-term clinical trials to support safe and evidence-based commercialization.

The purpose of the present work was to characterize the possible inhibition of pancreatic lipase by a tannin-rich extract obtained from the pinhão (Araucaria angustifolia seed) coat, based on the previous observation that this preparation inhibits α-amylases. Kinetic measurements of pancreatic lipase revealed that the pinhão coat tannin is an effective inhibitor. Inhibition was of the parabolic non-competitive type. The inhibition constants, \({\overline{K}}_{i1} \) and \({\overline{K}}_{i2} \), were equal to 332.7 ± 146.1 µg/mL and 321.2 \(\pm\) 93.0 µg/mL, respectively, corresponding roughly to the inhibitor concentration producing 50.

This study aimed to provide an updated critical review of the nutritional, therapeutic, biotechnological, and environmental aspects involved in the exploitation of Chenopodium quinoa Willd and its biowastes. Special attention was devoted to investigations of the therapeutic and nutritional properties of different parts and varieties of quinoa as well as of the use of the biowaste resulting from the processing of grain. Studies published from 2018 onward were prioritized. Extracts and fractions obtained from several Chenopodium quinoa matrices showed antioxidant, antidiabetic, immunoregulatory, neuroprotective, and antimicrobial effects in in vitro and in vivo models and some clinical studies. The activities were attributed to the presence of phytochemicals such as polyphenols, saponins, peptides, polysaccharides, and dietary fibers. Quinoa wastes are abundant and low-cost sources of bioactive molecules for the development of new drugs, natural antioxidants, preservatives, dyes, emulsifiers, and carriers for food and cosmetics applications. Among the demands to be fulfilled in the coming years are the following: (1) isolation of new bioactive phytochemicals from quinoa varieties that are still underexploited; (2) optimization of green approaches to the sustainable recovery of compounds of industrial interest from quinoa by-products; and (3) well-conducted clinical trials to attest safety and efficacy of extracts and compounds.

Neste trabalho propomos o aproveitamento dos resíduos de laranja gerados após remoção do suco como substrato para a obtenção de enzimas hidrolíticas e oxidativas envolvidas na degradação de materiais lignocelulósicos, tais como: lacase (EC 1.10.3.2), manganês peroxidase (EC 1.11.1.14), xilanase (EC 3.2.1.8) e endo-1,4 glucanase (EC 3.2.1.4), pelo basidiomiceto Pleurotus ostreatus cultivado em estado sólido. O fungo desenvolveu-se bem no resíduo, em diferentes umidades iniciais e sem a necessidade de qualquer suplementação. O meio à base de resíduo de laranja proporcionou a obtenção de elevadas atividades de enzimas com grande potencial de uso industrial, especialmente lacase (74,3 U.g -1 substrato após 15 dias de cultivo) e manganês peroxidase (6,8 U.g -1 substrato após 30 dias de cultivo). In this work, orange waste as a substrate to produce hydrolytic and oxidative enzymes involved in the degradation of ligninocellulolytic materials, such as laccase (EC 1.10.3.2), manganese peroxidase (EC 1.11.1.14), xylanase (EC 3.2.1.8) and endo-1,4 glucanase (EC 3.2.1.4) by the Basidiomycete Pleurotus ostreatus was used. The fungus was able to grow in the orange waste at different moisture contents without any supplementation. The orange waste medium provided the conditions to produce high activities of important industrial enzymes, especially laccase (75 U.g -1 substrate, after 15 days of cultivation) and Mn peroxidase (6.8 U.g-1 substrate, after 30 days of cultivation)
