OBJECTIVE To probe into the influences of different granule sizes and to prepare procedures on rational clinical usage of rhubarb based on chemical equivalence. METHOD The effects of particle size, extract solvent, extract time and repeat times, and pre-extract or pro-extract of rhubarb on the extract amounts of the anthraquinones (AQs) were compared. (More)
A rapid, simple and sensitive ultra high-performance liquid chromatography (UHPLC-MS/MS) method was established for determining the absorption amount of emodin in the five digestive segments of rat. Plasma samples were pre-purified by solid-phase extraction (SPE) with Oasis MAX cartridge. Separation of emodin and 1,8-dihydroxyanthraquinone (internal(More)
