Antioxidant activity in vitro of the selenium-contained protein from the Se-enriched Bifidobacterium animalis 01

Antidiabetic and in vitro antioxidant potential of Hybanthus enneaspermus (Linn) F. Muell in streptozotocin–induced diabetic rats

“…The antioxidant activity of AHE was evaluated on the basis of the radical scavenging effect of the stable DPPH free radical [15] . Ascorbic acid was used as a standard compound in DPPH assay and absorbance was at 517 nm.…”

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

“…1, 1-diphenyl-2-picryl-hydrazil (DPPH) method was used to determine the free radical scavenging activity of P. murex fractions, where 5 mL of DPPH (100 毺M/mL) solution was added to 1mL of different fractions as well as standard 毺g/mL) [7] . The absorbance was then measured 30 min later at 517 nm and the free radical scavenging activity was calculated in the form of IC 50 value according to the standard equation using ascorbic acid as control which was mentioned here.…”

“…When the generation of the active oxygen-free radical is overgrown many degenerative diseases, such as brain dysfunction, cancer, heart diseases, age-related degenerative conditions, declination of the immune system, cancer, coronary arteriosclerosis, ageing processes, carcinogenesis, gastric ulcer and DNA damage arise [5][6][7][8][9] . Thus, it is essential to develop and utilize effective natural antioxidants so that they can protect the human body from free radicals and retard the progress of many chronic diseases.…”

Comparative Evaluation of Antidiabetic and Antioxidant Potency of Different Extracts Obtained From Memecylon Species

“…The reducing power assay of different extracts of Memecylon species was evaluated according to the method described by Shen [13]. Different concentrations (250 to 1000 μg/ml) of the sample (1 ml) was mixed with PBS buffer (pH 7.4, 0.02M), 1.0 ml potassium ferricyanide (1.0%, w/v) and the reaction was incubated at 50 °C for 20 min.…”
