Recipe for uncovering the bioactive components in herbal medicine.
30 Aug 2009 
Using whole chromatographic profiles and measurements of total bioactivity as input, a quantitative pattern-activity relationship (QPAR) approach is proposed as a general method for providing two pieces of crucial information about complex bioactive ... Read more...
30 Aug 2009 A reversed-phase high-performance liquid chromatography method was established for the simultaneous determination of four major constituents, namely myricitrin, hyperin, quercitroside, and quercetin in Folium Rhododendri Micranthi. The optimal ... Read more...
10 Aug 2009 The antioxidant properties of wine have been largely related to the reactive oxygen species (ROS) scavenging ability of phenolic compounds. Polyphenolic compounds are hardly absorbed and quickly transformed into metabolites. Their antioxidant ... Read more...
