Angelica sinensis (AS, Danggui in Chinese) is an important herbal component of various traditional formulae for the management of asthenia and its tonic effects. Although AS has been shown to ameliorate cognitive damage and nerve toxicity in D-galactose (D-gal)-elicited senescent mice brain, its effects on liver and kidney injury have not yet been explored. In this work, mice were subjected to hypodermic injection with D-gal (200 mg/kg) and orally gavaged with AS (20, 40, or 80 mg/kg) once a day for 8 successive weeks.

Berberrubine (BB) is deemed as one of the major active metabolite of berberine (BBR), a naturally-occurring isoquinoline alkaloid with appreciable anti-UC effect. This study aimed to comparatively investigate the therapeutic effects of BB and BBR on dextran sodium sulfate (DSS)-induced mouse colitis model, and explore the potential underlying mechanism.

An ultra-high performance liquid chromatography tandem mass spectrometry (U-HPLC-MS/MS) method was developed and validated to determine liensinine and isoliensinine in rat plasma simultaneously. Plasma samples were prepared using protein precipitation with acetonitrile. The two analytes and the internal standard pirfenidone were separated on an Acquity U-HPLC BEH C18 column with the mobile phase of acetonitrile and 1% formic acid in water with gradient elution at a flow rate of 0.
