The invention belongs to the technical field of
plant chemical
component analysis, and discloses a multi-species
polyphenol flavonoid compound high-
throughput identification method which comprises the following steps: S1, constructing a cross-platform compatible MSP
database; s2, sample pretreatment: carrying out ultrasonic extraction on a
plant sample with 70%
methanol, centrifuging, and filtering a supernatant with a filter membrane; wherein the
plant sample comprises folium cortex eucommiae, rosemary, day lily, sea-buckthorn, herba houttuyniae or tea leaves; s3, carrying out liquid
chromatography-
mass spectrometry detection; s4,
data matching and identification: using
open source mass spectrum
data processing software, setting the
mass deviation to be less than or equal to 5ppm, the
retention time deviation to be less than or equal to 0.3 min and the Dot product
score to be more than or equal to 80%, and carrying out automatic identification; the technical problems that
mass spectrum platform data is isolated, multi-species batch detection is difficult, the detection consistency is influenced by the matrix effect, and the compound identification efficiency is low are solved.
