<br/><br/> PHY906 is a Chinese medicine formulation prepared from four medicinal herbs for adjuvant cancer chemotherapy. In this paper, liquid chromatography/electrospray ionization time-of-flight mass spectrometry (LC/ESI-TOFMS)was used to clarify the chemical composition of PHY906. The aqueous extract of PHY906 was separated on a Waters Atlantis C18 column, and was eluted with acetonitrile/ 0.05
