Schisandra chinensis, a traditional Chinese medicine (TCM), has been used to treat sleep disorders. Zebrafish sleep/wake behavioral profiling provides a high-throughput platform to screen chemicals, but has never been used to study extracts and components from TCM. In the present study, the ethanol
The systems of mobile phase for the determination of gamma-schisandrin in Schisandra chinensis and its preparations were developed by high performance liquid chromatography (HPLC). The separation was performed on a Shim-pack VP-ODS column (250 mm x 4.6 mm, 5 microm) at 30 degrees C, the detection
High-speed counter-current chromatography (HSCCC) was successfully applied to the preparative separation and purification of deoxyschisandrin and gamma-schisandrin from the crude petroleum ether extracts of Schisandra chinensis (Turcz.) Baill. The optimum solvent system composed of
The objective of this study is to develop a process consisting of ultrasonic-assisted extraction, silica-gel column chromatography and crystallization to optimize pilot scale recovery of schisandrin B (SAB) from Schisandra chinensis seeds. The effects of five independent variables including
Schisandrin B (SchB), an active ingredient extracted from Schisandra chinensis (Turcz.) Baill, has been known to have anti-oxidant and anti-inflammatory activities. In this study, we investigated the anti-inflammatory effects and mechanism of SchB in LPS-stimulated human umbilical vein endothelial
It has been established that poor outcomes in ischemic stroke patients are associated with the post-reperfusion inflammatory response and up-regulation of TLR4. Therefore, suppression of the TLR4 signaling pathway constitutes a potential neuroprotective therapeutic strategy. Schisandrin B, a
Cyclosporine A (CsA) is a potent immunosuppressive agent whose clinical usage is limited by nephrotoxicity. Schisandrin B (SchB), isolated from the fruit of Schisandra chinensis, is a natural compound with multiple pharmacological activities that has been shown to attenuate organ injury caused by
The fruit of Schisandra chinensis has been used in the traditional Chinese medicine for thousands of years. Accumulating evidence suggests that Schisandrin B (Sch B) has cardioprotection effect on myocardial ischemia in vitro. However, it is unclear whether Sch B has beneficial effects on continuous
BACKGROUND
The principal bioactive lignan of Schisandra chinensis fructus, commonly used for traditional Chinese medicine, is schisandrin A. Schisandrin A has been widely reported as being very effective for the treatment of liver disease. However, the mechanisms of its protective effects in liver
Mice were intragastrically treated with single doses (0.05-0.8 g/kg) of schisandrin B (a dibenzocyclooctadiene derivative isolated from the fruit of Schisandra chinensis). Twenty-four hours after schisandrin B administration, the serum triglyceride level was increased by 10-235% in a dose-dependent
Schisandrin A and B (Sch A and B) are the main effective components extracted from the oriental medicine Schisandra chinensis which is traditionally used to enhance mental and intellectual function. Although their neuroprotective effects have been demonstrated, their influences on neurogenesis are
This study examined the effect of schisandrin, one of the major lignans isolated from Schisandra chinensis, on spontaneous contraction in rat colon and its possible mechanisms. Schisandrin produced a concentration-dependent inhibition (EC₅₀=1.66 μM) on the colonic spontaneous contraction. The
Pulmonary arterial smooth muscle cells (PASMCs) in the medial layer of the vessel wall are involved in vessel homeostasis, but also for pathologic vascular remodeling in diverse diseases, such as pulmonary arterial hypertension (PAH). Pulmonary vascular remodeling in PAH results in vascular
Mitochondrial decay is a major cause of aging, leading to the subsequent death of aerobic organisms including humans. In the present study, we examined the effects of supplementation with schisandrin B (Sch B, a dibenzocyclooctadiene derivative isolated from the fruit of Schisandra chinensis),
Schisandrin B, an active ingredient isolated from the fruit of Schisandra chinensis, increased serum and hepatic triglyceride levels in mice. In the present study, the effective kinetics of schisandrin B on serum/hepatic triglyceride and total cholesterol levels in mice without and with the
