The invention discloses a
fingerprint detection method for a Puyuan
stomach harmonizing
capsule, and belongs to the field of
traditional Chinese medicine detection. Comprising the following steps: performing
high performance liquid chromatography detection on a
system applicability solution, a reference substance solution, a medicinal material solution and a
test solution to obtain chromatograms; chemical components of chromatographic peaks in the
fingerprint spectrum are determined according to the chromatogram, the chemical components are
caffeic acid serving as a first peak,
tetrahydropalmatine serving as a second peak,
chicoric acid serving as a third peak,
ammonium glycyrrhizinate serving as a sixth peak, alpha-cyperone serving as an eighth peak and 11-carbonyl-beta-acetyl masticinic acid serving as a tenth peak, the second peak and the fourth peak are derived from rhizoma
corydalis, the eighth peak is derived from rhizoma cyperi, the seventh peak, the ninth peak and the tenth peak are derived from
frankincense, and the seventh peak, the ninth peak and the tenth peak are derived from beta-acetyl masticinic acid. The No.1 peak, the No.3 peak and the No.5 peak are derived from
dandelion, and the No.6 peak is derived from liquorice. The method is applied to the detection of the Puyuan
stomach harmonizing
capsule, and solves the problems of complicated operation and single
quality control index of rhizoma
corydalis, rhizoma cyperi and vinegar
frankincense in the existing detection method.
