متن کاملSimultaneous determination of eight major bioactive compounds in Dachengqi Tang (DT) by high-performance liquid chromatography
BACKGROUND Dachengqi Tang (DT) is a common traditional Chinese medicine formula for expelling neire ('internal heat') in the stomach and intestines. There was no reliable analytical method available for the quality control of DT. METHODS A high-performance liquid chromatography (HPLC) method with a reverse phase C18 column (150 x 4.6 mm) was developed. The mobile phase was methanol with 0.2% ...

متن کاملDetermination of some B Vitamins in Sour Cherry Juice Using Dispersive Liquid-liquid Microextraction Followed by High-performance Liquid Chromatography
Dispersive liquid-liquid microextraction method (DLLME) combined with high-performance liquid chromatography-ultraviolet detection (HPLC-UV) was used to determine thiamine (B1), nicotinamide (B3) and pyridoxine (B6) in sour cherry juice. This method was rapid, simple and sensitive. Separation was accomplished using a C18 column. The optimum chromatographic conditions were found to be: mobile ph...
