Embodiment 1

[0066] The optimization of embodiment 1 chromatographic conditions

[0067] The preparation method of the test solution: Weigh 5g of Yixuean granules, add 50mL of water to dissolve, add 0.3mL of dilute hydrochloric acid, stir well, let stand for 20min, filter, add water-saturated n-butanol to extract 5 times, each time 15mL, divide Take n-butanol extracts, combine them, let stand for 1h, separate to obtain n-butanol liquid, recover n-butanol, add 5 mL of methanol to the residue, centrifuge, and take supernatant to obtain the test solution.

[0068] 1-1 Selection of chromatographic column

[0069] The other determination conditions of high performance liquid chromatography are the same. Welchrom C18 column (4.6mm×250mm, 5μm), Hypersil C18 column (4.6mm×250mm, 5μm) and Phenomenex Gemini C18 column (4.6mm×250mm, 5μm) three column, the resulting chromatograms are divided into figure 1 , figure 2 , image 3 shown by image 3 It can be seen that the Phenomenex Gemini C18 colum...

Embodiment 2

[0078] The optimization of embodiment 2 sample pretreatment method

[0079] Chromatographic conditions of high-performance liquid chromatography: the chromatographic column adopts Phenomenex Gemini C18 column (4.6mm × 250mm, 5 μm); the guard column adopts Phenomenex C18 (4 × 3.0mm); mobile phase: methanol-0.1% glacial acetic acid; gradient elution Procedure: Time Gradient

[0080] 0min→11min→16min→29min→30min→35min→45min→55min→70min→95min; the corresponding gradient elution solution is composed of mobile phase A methanol and mobile phase B 0.1% glacial acetic acid according to the following volume ratio, mobile phase A Volume percentage gradient 5%→16%→17%→30%→34%→34%→35%→45%→45%→70%, mobile phase B volume percentage gradient 95%→84%→83%→70 %→66%→66%→65%→55%→55%→30%;; detection wavelength: 256nm; flow rate: 1.0mL·min-1; column temperature: 25°C; injection volume: 5μL.

Abstract

The invention discloses an HPLC (High Performance Liquid Chromatography) fingerprint spectrum establishment method for Yixuean granules. Protocatechuic acid is adopted as a reference, and gradient elution is performed to obtain a fingerprint spectrum of a common mode of medicinal materials of a Zhuang medicament blumea riparia by HPLC. The fingerprint spectrum has totally 21 chromatographic peaks, chemical components of the Yixuean granules can be completely reflected, the information amount is large, and the method is high in precision, reproducibility and stability and significant for quality control and clinical efficacy of the Yixuean granules.

Description

technical field [0001] The invention relates to the field of drug detection, in particular to a method for establishing HPLC fingerprints of Yixuan granules. Background technique [0002] Yixue'an Granule is a Chinese patent medicine for treating gynecological anemia. Clinically, it is used for persistent postpartum lochia, unclean uterine bleeding after artificial abortion, and blood stasis syndrome in TCM. [0003] With the application of new technologies and methods in recent years, many new ideas have appeared in the research of compound Chinese medicines. The use of fingerprints to study compound Chinese medicines is one of them. Fingerprints are of great significance to the quality control research and quality control standards of Chinese medicine compound . However, there are still relatively few studies on the establishment of fingerprints of Yixuan granules. [0004] The invention patent with the authorized notification number CN104458993B discloses a method for ...
