## Abstract An improved quality control method was developed to simultaneously determine 15 major constituents (eight flavonoids and seven saponins) in various Radix Astragali preparations, using SPE for pretreatment of samples, HPLC with diode‐array and evaporative light scattering detectors (DAD‐
## Abstract A microwave assisted extraction (MAE) procedure was first developed for the simultaneous determination of isoflavonoids and astragalosides in Radix Astragali (RA). MAE showed the highest extraction efficiency when compared to Soxhlet, reflux, and ultrasonic extraction. It was found that
## Abstract The matrix solid‐phase dispersion (MSPD) was applied for extracting seven sulfonamides (SAs) in liver samples. The separation and determination were carried out by high‐performance liquid chromatography. The analytes were derivated with fluorescamine and detected with fluorescence detec
