Abstract

The invention discloses a construction method of a wild chrysanthemum flower UPLC fingerprint spectrum. The method comprises the following steps: crushing a wild chrysanthemum flower medicinal material, precisely weighing, adding methanol, performing ultrasonic treatment after weighing, filtering by use of a microfiltration membrane, and taking subsequent filtrate to obtain a test sample solution; respectively taking chlorogenic acid, galuteolin, luteolin and linarin, precisely weighing, and dissolving by use of the methanol to obtain a reference solution; and respectively measuring the test sample solution and the reference solution by use of an ultrahigh-efficiency liquid chromatogram system to generate chromatogram peaks of the test sample solution and the reference solution so as to generate the wild chrysanthemum flower UPLC fingerprint spectrum. The construction method of the wild chrysanthemum flower UPLC fingerprint spectrum related to the invention is simple, easy to operate and greatly improved in spectrum analytic capability, and has the advantages of improving the accuracy of results and greatly improving the stability and sensitivity of the detection of the fingerprint spectrum.

Description

technical field [0001] The invention relates to the field of fingerprint atlas construction, in particular to a method for constructing UPLC fingerprint atlas of wild chrysanthemum. Background technique [0002] At present, Chinese herbal medicine plays a huge role in the field of traditional Chinese medicine treatment, and Chinese herbal medicine, especially some Chinese medicine granules, is convenient in the process of taking. The wild chrysanthemum is the flower head of the perennial herb of the Compositae family, which is similar to the chrysanthemum. It grows wild on hillside grasslands and beside roadsides. It is better to be yellow, sessile, complete, fragrant, and not fully bloomed. Wild chrysanthemum can be widely used to treat boils, carbuncles, sore throat, red eyes due to wind-fire, headache and dizziness, etc. Quality standard control is uneven. Fingerprints are used as a detection method to control the quality uniformity and stability of traditional Chinese...
