[ 1 ] - Identification of chemical constituents in the extract and rat serum from Ziziphus jujuba Mill. by HPLC-PDA-ESI-MSn

Chinese jujube (Ziziphus jujuba Mill.) has long been widely used for human consumption and medicinal purposes in China. It has been reported to possess several vital biological activities. However, the systematic study on the chemical constituents absorbed into plasma and their metabolites is still insufficient. A high-performance liquid chromatography-photodiode array detector-electrospray ion...

[ 2 ] - Systematic analysis of main constituents in rat biological samples after oral administration of the methanol extract of Fructus Aurantii by HPLC-ESI-MS/MS

High performance liquid chromatography (HPLC) with diode array detection (DAD) and electrospray ionization tandem mass spectrometry (ESI/MS/MS) was used to analyze the main components in the methanol extract of Fructus Aurantii (FA) and the metabolites in rat biological samples after oral administration of the methanol extract of FA. There were 31 constituents identified in the extract of FA in...

[ 3 ] - Isolation, Purification, Characterization and Effect upon HepG2 Cells of Anemaran from Rhizome Anemarrhena

The rhizome of Anemarrhena asphodeloides is used as food and traditional Chinese medicine for its hypoglycemic effect. The aim of this study was to investigate the isolation, purification and hypoglycemic activity of Anemaran as the active component. The influence factors (isolation duration, ratio of residuals to water and extracting times) during the isolation process were evaluated. The opti...

[ 4 ] - Effects of Space Flight on the Chemical Constituents and Anti-Inflammatory Activity of Licorice (Glycyrrhiza uralensis Fisch)

Licorice, the oldest Chinese traditional medicine, is widely used in the treatment of human diseases. Due to the deficiency of wild resource, selecting and breeding becomes a key issue to expanding the supply of licorice. Spaceflight technology will become a new method for medicinal plants. The aim of this study was to investigate the effect of spaceflight on the components and anti-inflamma...

[ 5 ] - Antinociceptive and Smooth Muscle Relaxant Activity ofCroton tiglium L Seed: An In-vitro and In-vivo Study

The seed of Croton tiglium L. (SCT) is a well known folk medicine. In China, it has used to treat gastrointestinal disorders, intestinal inflammation, rheumatism, and so on. Previous studies established its purgative and inflammation properties. In addition, the effects of essential oil of SCT on intestinal transit and gastrointestinal tract has been studied. In the present study, we evalu...
