General description

L-(+)-Arabinose is a pentose sugar that occurs naturally in corn fiber gum[1] and acacia gum.[2]

Biochem/physiol Actions

L-Arabinose is the naturally occurring isomer and is a constituent of plant polysaccharides. Most bacteria contain an inducible arabinose operon that codes for a series of enzymes and transporters that allows L-arabinose to be used as the sole carbon source in microbial culture.

Carnosol is a naturally occurring phytopolyphenol found in rosemary. Carnosol functions as antioxidant and anticarcinogen. In the present study, we compared the antioxidant activity of carnosol and other compounds extracted from rosemary. Carnosol showed potent antioxidative activity in alpha,alpha-diphenyl-beta-picrylhydrazyl (DPPH)

Carnosol, a naturally occurring bioactive phenolic diterpene originating from rosemary and sage, has been shown to exert antioxidant and anti-inflammatory effects. This study examined possible protective effects of carnosol on sodium nitroprusside (SNP)-induced cytotoxicity in C6 glial cells. Carnosol (1-10
