Moon-Hee Lee,Yeon-Kye Kim,Ho-Sung Moon,You Ah Kim,Na-Young Yoon,Chi-Won Lim,Hee-Yeon Park,Dae-Hee Kim +7 more
TL;DR: In this article, the in vitro antioxidant activities of five melania snails in the genus Semisulcospira (S. coreana, S. gottschei) were tested in detail.
Effect of iron concentration on growth, protein content and total phenolic content of chlorella sp. cultured in basal medium
TL;DR: In this article, the effect of Fe3+ concentration (0.35, 4.89, 9.44 and 13.99 mg/L) on the growth, protein content and total phenolic content of Chlorella sp. was determined on phase 7th, 14th, and 21st day of cultivation.

Investigation of Antioxidant Properties of Polygonatum orientale Desf and Tilia dasystyla Extracts by Different Methods and Solvents
TL;DR: In this article, the authors investigated the antioxidant properties of two native plants species, including Polygonatum orientale Desf and Tilia dasystyla extracts, which are obtained with three different solvents (water, ethanol, and methanol) and two extraction methods (sonication and water bath) by DPPH (2,2-Diphenyl-1-Picrylhydrazyl) and FRAP (Ferric Reducing Antioxidant Potential) methods.

Ethnopharmacological Study and Evaluation of the Antioxidant Activity of Ocimum basilicum L. Extracts
TL;DR: The aim of the present study was to research the traditional uses and the mode of application of O. basilicum in the M’sila region (northern Algeria), to estimate the content of polyphenols and flavonoids in methanolic and aqueous extracts of this plant and to evaluate the antioxidant activity of these extracts by the 2, 2’-diphenyl-1-picryl hydrazyl (DPPH).

Colorimetry of Total Phenolics with Phosphomolybdic-Phosphotungstic Acid Reagents
TL;DR: In this paper, the use of Folin-Ciocalteu reagent rather than the FolinDenis reagent, gallic acid as a reference standard, and a more reproducible time-temperature color development period was investigated.
