Embodiment 1
[0046] Embodiment 1 A kind of detection method of instant Suanzaoren Xinning drink solid beverage fingerprint, comprises the following steps:
[0047] Step 1, the preparation of instant Suanzaoren Xinning drink solid beverage test solution:
[0048] Take 8 batches of instant Suanzaoren Xinning drink solid beverage clear paste sample 20g (Spinning jujube kernel 3g, ginseng 2g, Poria cocos 2.4g, wolfberry 1.4g, cinnamon 1g, kudzu root 1.4g, bellflower 1g, jujube 1.4g, lotus seeds 1.2g g, lily 1.2g, cassia seed 1g, gardenia 1g, licorice 1g, hawthorn 1g) were placed in a 500mL round bottom bottle, added methanol solution 250mL, ultrasonically extracted for 30min, the extract was centrifuged at 12000 rpm for 5min, and the supernatant was passed through 0.45 μm microporous membrane to obtain the test solution;
[0049] Step 2, preparation of mixed reference solution:
[0050] Take accurately weighed reference substances of chlorogenic acid, puerarin and formononetin, place them in...
Embodiment 2
[0059] The methodological research of embodiment 2 fingerprint spectrum detection:
[0060] 1. Methodological investigation
[0061] 1.1 Inspection of precision
[0062] Get instant Suanzaoren Xinning beverage solid beverage sample 20g (same as embodiment 1), according to the need testing sample preparation method of above-mentioned embodiment 1, prepare need testing solution, continuous sample injection 6 times, each injection volume 10 μ L, Detect by above-mentioned embodiment 1 chromatographic conditions, measure its HPLC chromatogram, investigate 27 common fingerprint peaks in chromatogram, the result shows, the retention time RSD of common fingerprint peak is all less than 1.5%, and common peak peak area RSD is all less than 2.8% %, indicating that the precision of the instrument is better.
[0063] 1.2 Stability investigation

Abstract
The invention discloses a detection method for the fingerprint spectrum of an instant spina date seed heart calming solid beverage. The method comprises the following steps of: step 1, preparing a test solution; step 2, preparing a mixed reference substance solution; step 3, respectively and precisely sucking the mixed reference substance solution and the test solution, injecting the mixed reference substance solution and the test solution into a liquid chromatograph, and recording chromatograms; step 4, exporting the fingerprint spectrum of the test solution from an instrument, importing the fingerprint spectrum into a traditional Chinese medicine chromatographic fingerprint spectrum similarity evaluation system, and selecting chromatographic peaks existing in chromatograms of different batches of instant spina date seed heart-calming drink solid beverages as common peaks; generating a control fingerprint spectrum of the instant spina date heart-calming drink solid beverages by using an average value calculation method; calculating the relative retention time and the relative peak area of each common peak; and comparing with the spectrum with the spectrum of the mixed standard product, and identifying main component peaks. The fingerprint spectrum can comprehensively and objectively characterize the quality of the instant spina date seed heart-calming drink solid beverage. The detection method has the advantages of simplicity, stability, high precision, good reproducibility and the like.
Description
technical field [0001] The invention relates to a method for detecting the instant solid beverage of traditional Chinese medicine, in particular to a method for detecting the fingerprint of the instant Suanzaorenxinningyin solid beverage. Background technique [0002] Insomnia is the most common sleep disorder clinically.
