Antioxidant activities of Salvia miltiorrhiza and Panax notoginseng

Free radical scavenging and antimicrobial properties of extracts of wild mushrooms

“…TRE and TCE exhibited a significant superoxide anion scavenging effect of 72.95% and 98.80% respectively at 2.0 mg/mL concentration. Superoxide is biologically important since it can be decomposed to form stronger oxidative species such as singlet oxygen and hydroxyl radicals hence, they are very harmful to cellular components of biological systems (27). Table 3 shows the results of antimicrobial effect of extracts on selected microorganisms.…”

Pedalium murex Linn (Pedaliaceae) fruits: a comparative antioxidant activity of its different fractions

“…Nitric oxide or reactive nitrogen species generally formed when their reaction occurs with oxygen or super oxides such as NO 2 , N 2 O 4 , N 3 O 4 , NO 3 -and NO 2 -which are highly reactive in nature. Excessive production of NO leads to the ill effects and can cause detrimental to human body so that it can lead to disorders like inflammation, cancer and other pathological complications [6] .…”

“…Natural antioxidants, which are ubiquitous in fruits, teas, vegetables, cereals, and medicinal plants, are employed not only for the prevention and treatment of various diseases caused by oxidative damage, but also for improving the shelf life of food products, and they have received great attention since they are effective free radical scavengers, by donating hydrogen to highly reactive radicals, thereby preventing further radical formation [1][2][3][4] .…”

Phytochemical Evaluation and Antioxidant Activity of Essential Oil, and Aqueous and Organic Extracts of Artemisia dracunculus

“…Free radicals and reactive oxygen species (ROS) are highly reactive molecules, formed in all tissues during normal cellular metabolism (1). However, different environmental factors, including tobacco smoke, pollutants, ionizing radiations, synthetic pesticides, and solvents are able to increase their production (2).…”
