Embodiment 1
[0060] 1. Instruments and reagents
[0061] 1.1 Instrument: electronic balance Mettler Toledo XP205DR (d=0.01mg), Mettler ToledoMS204S (d=0.1mg), high-frequency numerical control ultrasonic cleaner (KQ-300TD, Kunshan Ultrasonic Instrument Co., Ltd.) Simplicity UV pure water machine (Millipore) , High-performance liquid chromatography (Agilent 1260), freeze dryer (Christ, ALPHA2-4LD plus, Germany), rotary evaporator N-1200A (EYELA Shanghai Instrument Co., Ltd.).
[0062] 1.2 Reagents: Acetonitrile and phosphoric acid are chromatographically pure, water is purified water, and other reagents are analytically pure.
[0063] 1.3 Test drug: reference substance of paeoniflorin (China Institute for Food and Drug Control, 110736-201539, 110736-201741), reference substance of ferulic acid (China Institute for Food and Drug Control, 110773-201313), reference substance of loganin (China Food and Drug Control Institute, 111640-201005, 111640-201707), morroniside reference substance (China...
Embodiment 2
[0164] In this example, the fingerprints prepared in Example 1 are used to detect unqualified Yangjing Zhongyu decoction with missing raw materials.
[0165] With reference to the method of 2.1 of Example 1, unqualified sample 1 (raw material formula is rehmannia glutinosa: wine angelica: wine cornus=2:1:1), unqualified sample 2 (raw material formula is rehmannia glutinosa: wine white peony root: Wine Cornus = 2:1:1), unqualified sample 3 (raw material formula is rehmannia glutinosa: wine angelica: wine white peony = 2:1:1), unqualified sample 4 (raw material formula is wine angelica: wine white peony : wine cornus=1: 1: 1), and with reference to the method of 2.3 of embodiment 1, prepare the unqualified sample need testing solution, the method of 2.4 with reference to embodiment 1 prepares mixed reference substance solution, then with reference to embodiment 1 The chromatographic conditions of 2.2 and the assay method of 2.5 are used for detection. Detect this above-mentione...
Embodiment 3
[0169] In this example, the fingerprints prepared in Example 1 are used to detect Yangjingzhongyujianpao.
[0170] The preparation of need testing solution: get about 1g of Yangjingzhongyu decoction paste, accurately weighed, accurately add 50mL of 70% methanol, seal it up, weigh, ultrasonically treat (power 300W, frequency 40kHz) for 30 minutes, take out, Allow to cool, weigh again, make up the lost weight with 70% (volume percent) methanol, shake well, filter, and take the filtrate to obtain the test solution. All the other operating methods are the same as in Example 1.
[0171] The results of the fingerprints showed that compared with the control fingerprints, all 14 common peaks appeared, and the similarity was above 0.95. The results show that the fingerprints constructed in Example 1 can also be used for quality control of Yangjingzhongyujianpao.
