Solvent effects on phytochemical constituent profiles and antioxidant activities, using four different extraction formulations for analysis of Bucida buceras L. and Phoradendron californicum
Simon Bernard Iloki-Assanga,Lidianys María Lewis-Luján,Claudia Lizeth Lara-Espinoza,Armida A. Gil-Salido,Daniela Fernandez-Angulo,José Luis Rubio-Pino,David D. Haines +6 more
TL;DR: It is revealed that Bucida buceras exhibited optimal antioxidant capacity when acetone was used as extraction solvent; and the highest yield of phenols and flavonoids were obtained from the P. californicum oak, using methanol and aqueous solvents, respectively.
Drought Stress Effects on Growth, ROS Markers, Compatible Solutes, Phenolics, Flavonoids, and Antioxidant Activity in Amaranthus tricolor
Umakanta Sarker,Shinya Oba +1 more
TL;DR: The increased content of ascorbic acid indicated the crucial role of the ASC–GSH cycle for scavenging ROS in A. tricolor cultivar, and positive correlations among MDA, H2O2, compatible solutes, and non-enzymatic antioxidant suggested that compatible solute andnon-enzysmatic antioxidant played vital role in detoxifying of ROS in the cultivar.

The antioxidant and free-radical scavenging activities of extract and fractions from corn silk (Zea mays L.) and related flavone glycosides
TL;DR: In this paper, the authors evaluated both the antioxidant and free-radical scavenging activities of extract and fractions from corn silk and identified two flavone glycosides showing potent antioxidant activity were isolated from BF and identified, by comparing spectral data (UV, FAB-MS and NMR) with literature values, to be isoorientin-2″- O - α - l -rhamnoside and 3′-methoxymaysin.

Recovery of natural antioxidants from spent coffee grounds
TL;DR: The total phenolic content was strongly correlated with the DPPH scavenging activity, suggesting that phenolic compounds are mainly responsible for the antioxidant activity of SCG.

Bauhinia variegata Leaf Extracts Exhibit Considerable Antibacterial, Antioxidant, and Anticancer Activities
TL;DR: Polar extracts demonstrated appreciable metal ion chelating activity at lower concentrations, and many extracts showed significant antioxidant response in beta carotene bleaching assay, while terpenoids and alkaloids were present in nonpolar and ethanol extracts.

Review of the biological properties and toxicity of bee propolis (propolis)
TL;DR: Although reports of allergic reactions are not uncommon, propolis is relatively non-toxic, with a no-effect level (NOEL) in a 90-mouse study of 1400 mg/kg body weight/day.

Antibacterial, antifungal and antiviral activity of propolis of different geographic origin.
TL;DR: It seems that propolis has general pharmacological value as a natural mixture and not as a source of new powerful antimicrobial, antifungal and antiviral compounds.
