A sensitive and selective high performance liquid chromatography–tandem mass spectrometric method (HPLC–MS/MS) has been developed for simultaneous analysis of 11 components (7 flavonoids and 4 phenolic acids) in Herba Scutellariae barbatae. Simultaneous separation of these 11 compounds was achieved on a C 18 analytical column with gradient elution of methanol and 0.1‰ acetic acid (v/v) at...
A novel qualitative and quantitative method using high performance liquid chromatography coupled with tandem mass spectrometry was developed for simultaneous analysis of 15 components including 10 coumarins, four phenolic acids and adenosine in Radix Glehniae, an important traditional Chinese medicine. The separation was performed on a C 18 column with isocratic elution consisted of 0.1% formic...
