Antioxidant activities of buckwheat extracts
The antioxidant activities of buckwheat (Fagopyrum esculentum Moench) extracts were evaluated and compared with butylated hydroxyanisole (BHA), butylated hydroxytoluene (BHT) and tertiaryExpand
Stability of tea polyphenol (-)-epigallocatechin-3-gallate and formation of dimers and epimers under common experimental conditions.
The results demonstrated that auto-oxidation and epimerization are the two major reactions causing the instability of EGCG. Expand
Antioxidative Phenolic Compounds from Sage (Salvia officinalis)
Ten phenolic compounds were isolated from a butanol fraction of sage extracts. Their structures were determined by spectral methods (NMR, MS, IR). Among them, a novel compound,Expand
Antioxidant Activities of Caffeic Acid and Its Related Hydroxycinnamic Acid Compounds
Hydroxycinnamic acid compounds are an important source of antioxidants due to their ubiquitous occurrence in the plant kingdom and their characteristic activities. In this study, we compared theExpand
The chemistry and biotransformation of tea constituents.
The present review summarizes the data concerning the chemistry and biotransformation of tea constituents and describes the major metabolic pathways for tea catechins. Expand

The glucuronidation of EGCG and EGC in human, mouse, and rat microsomes and by nine different human UGT 1A and 2B isozymes expressed in insect cells is characterized to provide foundations for understanding the biotransformation and biological activities of tea catechins. Expand
Carnosol, an antioxidant in rosemary, suppresses inducible nitric oxide synthase through down-regulating nuclear factor-kappaB in mouse macrophages.
The results suggest that carnosol suppresses the NO production and iNOS gene expression by inhibiting NF-kappaB activation, and provide possible mechanisms for its anti-inflammatory and chemopreventive action. Expand
Anti-inflammatory activity of natural dietary flavonoids.
Current knowledge and underlying mechanisms on anti-inflammatory activities of flavonoids and their implicated effects in the development of various chronic inflammatory diseases are summarized. Expand
Identification and characterization of methylated and ring-fission metabolites of tea catechins formed in humans, mice, and rats.
The presently characterized methylated EGCG metabolites and ring-fission products exist in substantial quantities and may contribute to the biological activities of tea. Expand
Effective inhibition of MERS-CoV infection by resveratrol
It is perceived that resveratrol can be a potential antiviral agent against MERS-CoV infection in the near future. Expand
