Antioxidant activity and total phenolic content of Agaricus brasiliensis (Agaricus blazei Murril) in two stages of maturity

Phenolic Compounds and Antioxidant Activity of <i>Castanopsis</i> <i>phuthoensis</i> and <i>Castanopsis</i> g<i>randicicatricata</i>

“…Several previous studies reported that the antioxidant property of plants and their phenolic contents are highly correlation [1,10,32,33]. This study indicated a highly significant correlation between phenolic contents and antioxidant activities in extracts of Castanopis species (Table 5).…”

“…Antioxidants are molecules which can delay or inhibit cellular damages from free radicals existing in biological systems and to be generated in various metabolic processes [1,2]. There are two types of free radicals including reactive oxygen species and nitrogen species.…”

Efeito da extração de compostos fenólicos sobre a atividade antioxidante e antibacteriana in vitro de cogumelo-do-sol

“…Trabalhos têm relatado que o AbM apresenta atividade antibacteriana, como, por exemplo, na avaliação in vitro contra agentes patogênicos orais para humanos, tais como Streptococcus mutans (Lund et al, 2009), além de atividade antioxidante (Soares et al, 2009), antidiabética (Kim et al, 2005), forte atividade imunoestimulante (Yuminamochi et al, 2007), bem como efeitos antitumorais e anticâncer (Yu et al, 2009), entre outros.…”

“…Quanto ao acúmulo desses compostos, o conteúdo de fenólicos totais e atividade antioxidante foram estimados e comparados em fases jovens e maduras de corpos de frutificação de AbM, não obtendo-se diferença entre elas (Soares et al, 2009). Por outro lado, a composição nutricional e os componentes antioxidantes do AbM, incluindo os fenólicos totais, podem diminuir quando submetidos a tratamentos térmicos (Sun et al, 2011).…”

The effects of different solvents on bioactive metabolites and “in vitro” antioxidant and anti-acetylcholinesterase activity of Ganoderma lucidum fruiting body and primordia extracts

“…The mycelia, mature fruiting body and spores of G. lucidum contain over 400 different bioactive compounds, including triterpenoids, polysaccharides, nucleotides, sterols, steroids, fatty acids, proteins/peptides, and trace elements which have been reported to have a number of medicinal effects [3,4] such as immunomodulation, antitumor [5,6] anti-atherosclerotic [7], anti-inflammatory, anti-microbial [8], hypolipidemic [9], hepatoprotective [10], anti-diabetic, anti-androgenic, anti-angiogenic, anti-herpetic, anti-oxidative and radical-scavenging, anti-aging [11], hypoglycemic [12] and anti-ulcer properties [13].…”
