TL;DR: Flavonoids are a family of plant-derived compounds with potentially exploitable activities, including direct antibacterial activity, synergism with antibiotics, and suppression of bacterial virulence, and recent advances towards understanding these properties are described.

TL;DR: In this article, the authors examined the free radical scavenging capacity of 26 Thai indigenous plants to determine their potential as a source of natural antioxidants and found that chewing plants which have an astringent taste gave a significantly higher total phenolic content and flavonoid content.

TL;DR: The synthetic isoquinoline alkaloid virstatin, for example, inhibits the transcriptional regulator ToxT in Vibrio cholerae, preventing expression of cholera toxin and fimbriae and conferring in vivo protection against intestinal colonisation.

TL;DR: It is demonstrated that the water extract fractions of bitter gourd have different responses with different antioxidant methods, namely DPPH radical-scavenging activity and ferric reducing power.

TL;DR: In this paper, four fractions, namely, rice bran, rice husk, brown rice and milled rice of a Thai rice variety (Khao Dawk Mali 105), collected from three different growth sites, were analyzed to determine phenolic acid composition, γ-oryzanol and tocopherols content and their antioxidant capacity using the 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging and ferric reducing ability power (FRAP) assays.
