A xanthone was isolated from the hexane fraction of the Swertia chirayita plant and identified as 1,8-dihydroxy-3,5-dimethoxyxanthone (swerchirin). It has a very significant blood sugar lowering effect in fasted, fed, glucose loaded, and tolbutamide pretreated albino rat models. The ED50 for 40%
Mechanism of blood sugar lowering by the crude/impure swerchirin (SWI) isolated from the hexane fraction of Swertia chirayita was investigated. Single oral administration of SWI (50 mg/kg, body wt) to fed CF rats induced about 60% (max.) fall in blood glucose by 7 hr post-treatment. This was
The effect of aqueous extract of Swertia chirayita stem on the pro- and anti-inflammatory cytokines balance in primary joint synovium of adjuvant-induced arthritic mice has been studied. The level of pro-inflammatory cytokines was found elevated in the joint synovium of arthritic mice in comparison
Effect of Swerchirin (1:8 dihydroxy 3:5 dimethoxy xanthone) isolated from hexane fraction of Swertia chirayita on the blood sugar level of healthy and streptozotocin treated rats was studied. Streptozotocin was administered in citrate buffer (pH-4.5) intravenously / 35 and 65 mg/kg body wt to
The present work is to study the chemical constituents from petroleum ether fraction of Tibetan medicine Swertia chirayita by column chromatography and recrystallization. The structures were identified by physical and chemical properties and spectral data as swerchirin (1), decussatin (2),
The crude extract of Swertia chirayita, an important medicinal plant of Nepal, is locally used for many diseases including type 2 diabetes. In this study, crude aqueous and 12% ethanol solution extracts of S. chirayita collected from nine districts of Nepal were analyzed for anti-diabetic-linked
Swertia chirayita, has been commonly used under the name "Zang-yin-chen" for the treatment of liver infections, inflammation, abdominal pain, and bacterial infection in traditional Tibetan medicine. However, the bioactive components with anti-inflammatory activities and The mechanism of dose-dependent hypoglycemic effect, the margin of safety and ED50 of three structurally unrelated compounds, tolbutamide (TB), centpiperalone (CP) and a swerchirin-containing fraction (SWI) from the plant Swertia chirayita, were investigated in experimental models. After a single
Dexamethasone (DEX) an anti-inflamatory 9-fluoro-glucocorticoid, activates the cytosolic glucocorticoid receptor (GR) binding to its Ligand Binding Domain (LBD). The GR-ligand complex then translocates to the nucleus and binds to the Glucocorticoid Response Element (GRE) resulting up-regulation of
