Shuanghuanglian is a common traditional Chinese medicine prescription. It is an herbal formula composed of Lonicerae Japonicae Flos, Scutellariae Radix, and Forsythiae Fructus. A comprehensive understanding of Shuanghuanglian oral dosage forms components was obtained using a method based on ultra-high performance liquid chromatography coupled with time-of-flight mass spectrometry for the separation and characterization of Shuanghuanglian oral liquids, granules, soft capsules, and effervescent tablets. A total of 358 components were chemically defined or tentatively identified, including flavonoids, caffeic acid derivatives, lignans, coumarins, iridoids, triterpenes, and anthraquinones. The results will provide a basis for the general study of Shuanghuanglian and be meaningful for the composition identification of traditional Chinese medicine prescriptions.
