Objective. To investigate neuroprotective effects of scutellarin (Scu) in a rat model of cerebral ischemia with use of (18)F-fluorodeoxyglucose ((18)F-FDG) micro positron emission tomography (microPET). Method. Middle cerebral artery occlusion was used to establish cerebral ischemia. Rats were divided into 5 groups: sham operation, cerebral ischemia-reperfusion untreated (CIRU) group, Scu-25 gr...

Scutellarin (SCU) is one of the main components of traditional Chinese medicine plant Erigeron breviscapus (Vant.) Hand.-Mazz. In this paper, we studied the protective effects of SCU on human cardiac microvascular endothelial cells (HCMECs) against hypoxia-reoxygenation (HR) injury and its possible target-related proteins. Results of MTT assay showed that pretreatment of SCU at doses of 1, 5, a...

AIM To investigate the effects of scutellarin (Scu) on liver function after brain ischemia/reperfusion in Wistar rats. METHODS Rats were pretreated with Scu for 7 d and then subjected to a brain ischemia/reperfusion injury induced by a middle cerebral artery occlusion. The levels of nitric oxide (NO), xanthine oxidase (XOD), alanine transaminase (ALT), and aspartate aminotransferase (AST) in ...

A rapid and high-sensitivity liquid chromatography/tandem mass spectrometry (LC/MS/MS) method was developed for simultaneous determination of nine active constituents (baicalin, baicalein, wogonoside, wogonin, scutellarin, berberine, coptisine, ginsenoside Rb1 and ginsenoside Re) in rat plasma after oral administration of Banxia xiexin decoction (BXD). Biological samples were processed wtih ace...

Solid self-microemulsifying drug delivery systems (SMEDDS) have been used increasingly for improving the bioavailability of hydrophobic drugs. Labrasol® and Transcutol® are used widely as surfactant and solubilizer in the formulation of solid SMEDDS. We investigated the effects of spray-drying and the use of different solid carriers on concentrations of Labrasol® and Transcutol® in solid SMEDD...

A simple and reliable method has been developed with a new strategy named holistic analysis of multiple constituents to evaluate the quality of the well-known traditional Chinese medicine (TCM) Shuanghuanglian (SHL) oral liquid and soft capsule. Seven main constituents of the medicine, i.e., baicalein, baicalin, chlorogenic acid, wogonin, scutellarin, forsythin and hyperin, were selected as the...
