Antioxidant, antiapoptotic and amino acid balance regulating activities of 1,7-dihydroxy-3,4,8-trimethoxyxanthone against dimethylnitrosamine-induced liver fibrosis.

Liver fibrosis represents the consequences of a sustained wound healing response to chronic liver injury which could be caused by viral, autoimmune, drugs, and so on. Unfortunately, there was no effective therapy available for liver fibrosis in clinic. In this study, we identified the anti-fibrotic effects of 1,7-dihydroxy-3,4,8-trimethoxyxanthone (ZYC-1) on the dimethylnitrosamine (DMN)-induced rat model.

[Effect of Fuzheng Huayu capsule on serum metabolomics in rats with liver fibrosis induced by dimethylnitrosamine].

To investigate the effect of Fuzheng Huayu capsule(FHC) on serum metabolomics in rats with liver fibrosis induced by dimethylnitrosamine(DMN). The metabolic profiles of rat serum of normal group, model group, and FHC group were established by liquid chromatography-mass spectrometry technology. Furthermore, the levels of endogenous metabolites such as amino acids and bile acids were measured in each group.

Two xanthones from Swertia punicea with hepatoprotective activities in vitro and in vivo.

Ethnopharmacological Relevance: Swertia punicea Hemsl. (Gentianaceae) is more commonly known as "Ganyan-cao" and used mainly as a traditional Chinese folk medicine for the treatment of acute bilious hepatitis, cholecystitis, fever, intoxification and jaundice.

Materials And Methods: The active hepatoprotective constituents of Swertia punicea were purified using various column chromatography techniques.

Acetylcholinesterase inhibitive activity-guided isolation of two new alkaloids from seeds of Peganum nigellastrum Bunge by an in vitro TLC- bioautographic assay.

Acetylcholinesterase inhibitors (AChEIs) currently form the basis of the newest drugs available for the treatment of Alzheimer's disease. For the aim of screening effective AChEIs, the methanol extracts of the seeds of genus Peganum were found to show significant inhibitory activity of acetylcholinesterase enzyme (AChE) using an in vitro TLC-bioautographic assay. In further studies to seed of P.
