Rapid identification of coumarins from Fructus citri Sarcodactylis by UPLC/Q-TOF-MS.

Coumarins is a kind of important components in traditional Chinese medicine. Due to their special structure, they have significant pathological connections with many diseases. In this research, we established a rapid method to analyse the coumarins from Fructus citri Sarcodactylis by using the technique of ultra-performance liquid chromatography with quadruple time-of-flight mass spectrometry. Twenty-one coumarins were identified from Fructus citri Sarcodactylis, 10 were discovered for the first time. At the same time, a rapid sensitive method for identifying coumarins from Fructus citri Sarcodactylis was established.
