HPLC fingerprint spectrum detection method for traditional Chinese medicine

The invention discloses an HPLC (High Performance Liquid Chromatography) fingerprint spectrum detection method of a traditional Chinese medicine. The traditional Chinese medicine consists of eight medicinal materials, namely rheum officinale, mirabilite, scutellaria baicalensis, mangnolia officinalis, immature bitter orange, red paeony root, dandelion and liquorice. The HPLC fingerprint detection method of the traditional Chinese medicine is successfully established by exploring chromatographic conditions such as preparation of a test solution, a stationary phase, a mobile phase, an elution procedure, detection wavelength and the like, and can identify seven medicinal materials including rheum officinale, scutellaria baicalensis, mangnolia officinalis, immature bitter orange, radix paeoniae rubra, dandelion and liquorice as well as five components including paeoniflorin, magnolol, rhein, honokiol and baicalin. The peak separation degree is good, the peak area is large, and a foundation is laid for improving t
