Abstract
Description
TECHNICAL FIELD
[0001] The present application relates to a method for constructing a fingerprint of a Yangxin Dawaei Miceke preparation, a compound detection method and application. BACKGROUND
[0002] Yangxin Dawaei Miceke is derived from a classic compound preparation of Uyghur medicine, composed of 26 kinds of medicine such as Potentilla kleiniana flower, musk, sandalwood, eaglewood, safflower, rose, cassia, and box fruit tree, etc. It was first recorded in the Uyghur medicine classic ancient book "Medicine Essence", and has the effect of regulating the function of viscera. It can not only invigorate the spleen and stomach, and refresh the mind, but also can be used for treating chest tightness and pain, palpitation, weak spleen and stomach, decreased visual acuity, and fatigue.
[0003] However, with the deepening of research, the original standard obviously cannot meet the needs of modern medicine. How to construct an innovative methodology system for the quality standard improvement of traditional medicine, and realize the effective control of the quality of Yangxin Dawaei Miceke preparation, and ensure its safe and effective clinical efficacy, is a problem that must be considered by the technical personnel in the field.
[0004] Traditional Chinese medicine fingerprint refers to the chromatogram obtained by treating a certain traditional Chinese medicine, using a certain analysis method, which can indicate the characteristics of the traditional Chinese medicine. Under the premise that the effective components of the preparation are not completely clear, it is urgent to develop the chromatographic fingerprint of traditional Chinese medicine and establish a high-quality, stable and reliable quality control method. However, there is no research report on the fingerprint of Yangxin Dawaei Miceke preparation in the current literature, and the existing literature only determines the content of 1-2 components in the preparation. Therefore, in order to better monitor the content of each component in Yangxin Dawaei Miceke preparation and systematically clarify its pharmacodynamic material basis, it is urgent to establish a more comprehensive, simple and convenient quality control method for Yangxin Dawaei Miceke preparation. SUMMARY
[0005] The purpose of this invention is to provide a method for constructing a fingerprint spectrum of Yangxin Dawaimishik preparation, a compound detection method, and its application, so as to improve the problems of imperfect quality standards and inaccurate quality control of existing Yangxin Dawaimishik honey ointment.
[0006] Generally, the number of medicinal ingredients in existing traditional Chinese medicine preparations with clearly defined characteristic components is relatively simple, making fingerprint spectroscopy research and quantitative analysis relatively easy to control. However, Yangxin Dawa Yimishike honey ointment or preparations consist of 26 medicinal ingredients, including ox tongue flower, musk, sandalwood, agarwood, saffron, rose, cinnamon, and boxberry vine. The prescription is large, and even a single medicinal material contains hundreds or thousands of components. With 26 medicinal materials, the chemical composition is even more numerous and complex. The chemical components contained in traditional Chinese medicine are complex and difficult to control. Many components have low content and lack legal reference substances. Separation requires high sensitivity, making it even more difficult to identify the specific compounds. Moreover, the physicochemical properties (polarity, hydrophobicity, etc.) of the 22 components vary greatly. It is difficult to find a single chromatographic condition (column, mobile phase, gradient program) that allows all 22 peaks to reach baseline separation. In addition, co-eluting compounds can interfere with each other, causing ion suppression or enhancement effects at the ion source, significantly affecting the accuracy and precision of quantification, making it difficult to determine which compound the fragment ion signal specifically originates from. Therefore, the quality control research of Yangxin Dawayimisik honey ointment or preparations is quite difficult.

[0081] In some preferred embodiments, the ultra-high performance liquid chromatography-triple quadrupole tandem mass spectrometry detection includes the following steps:
[0082] a. Prepare a series of reference solutions of different concentrations for the analyte;
[0083] The above detection method was used to analyze and detect the reference solution and the test solution respectively; the peak area of the analyte in the reference solution and the peak area of the test solution were measured.
[0084] b. Based on the peak area and corresponding concentration of the analyte in the reference solution, perform linear regression to obtain the standard curve equation;
[0085] c. For the same analyte, the peak area measured by the test solution is substituted into its corresponding standard curve equation to obtain the concentration of the analyte.

[0093] The positive and progressive effects of this invention are as follows:
[0094] This invention constructed a fingerprint characteristic spectrum for Yangxin Dawaimexik preparation and identified 30 common peaks in the spectrum. The characteristic features of the fingerprint spectrum can effectively identify the authenticity of samples, determine the consistency of batches of products, effectively control product quality, and ensure relative stability of product quality. Similarity analysis of the fingerprint spectrum results show that the production process of Yangxin Dawaimexik preparation has good stability.
[0095] Based on the above research, UPLC-QQQ-LIT-MS / MS technology was used to determine the content of multiple indicators in the Yangxin Dawaimisik preparation, and a method for determining the content of 22 components was established for the first time. This method can simultaneously and effectively separate and quantitatively detect 22 components. Among the 22 components are several components with cardiovascular and cerebrovascular protective effects, including gallic acid, epicatechin, chlorogenic acid, and rosmarinic acid. This clarifies the pharmacodynamic material basis of the preparation and provides a scientific basis for establishing a quality control system.

[0119] Figure 2 A comparison chart (i.e., a common peak spectrum) of Yangxin Dawa Yimishike Honey Paste.
[0120] Figure 3 The figure shows the high-performance liquid chromatogram (HPLC) of sample S1, Yangxin Dawa Yimisik Honey Ointment. As can be seen from the figure, under these elution conditions, the chromatographic peaks are sharp, narrow, and without tailing; the baseline is stable with low noise; and the chromatographic separation is clear, indicating the optimal elution gradient. At a wavelength of 254 nm, the chromatographic peak information is abundant, the signal is strongest, and interference is minimal.
[0121] The specific data is shown in the table below.
[0122] Table 2
[0123]
[0124] The similarity was evaluated using a software system for evaluating the similarity of chromatographic fingerprints of traditional Chinese medicine. The results showed that the similarity of 14 batches of Yangxin Dawaimishik preparations ranged from 0.873 to 0.988, specifically 0.975, 0.982, 0.988, 0.980, 0.987, 0.970, 0.979, 0.985, 0.986, 0.942, 0.873, 0.920, 0.877, and 0.893, with minimal differences between batches. The experimental results indicate that the medicinal materials used in Yangxin Dawaimishik preparations are of consistent origin and the processing technology is stable.
[0125] Example 2: Investigation of the extraction solvent for the test sample
[0126] Except for the following conditions, the operation and conditions of Example 2 are the same as those of Example 1.
[0127] In the preparation method of the test solution, a 30% methanol aqueous solution is used as the solvent.
[0128] Example 3: Investigation of the extraction solvent for the test sample
[0129] Except for the following conditions, the operation and conditions of Example 3 are the same as those of Example 1.
[0130] In the preparation method of the test solution, a 70% methanol aqueous solution is used as the solvent.
[0131] Figure 4 The figure shows the high-performance liquid chromatogram of Yangxin Dawaimishik honey paste. As can be seen from the figure, when using 50% methanol aqueous solution (Example 1), 70% methanol aqueous solution (Example 3), and 30% methanol aqueous solution (Example 2) as extraction solvents, the sample solution extracted with 50% methanol aqueous solution showed more chromatographic peaks and a higher response value. Therefore, the optimal extraction solvent is 50% methanol aqueous solution.
[0132] Comparative Example 1: Elution Gradient Investigation
[0133] Except for the elution gradient conditions described below, all other operations are the same as in Example 1.
[0134] Table 3
[0135]
[0136] Figure 5 The figure shows the high-performance liquid chromatogram of Yangxin Dawa Yimishike Honey Ointment in Comparative Example 1. As shown in the figure, the chromatogram of Comparative Example 1 has a longer peak elution time, and the retention time of the same components fluctuates more than that of Example 1. The baseline is unstable and there is baseline drift and noise interference.
[0137] Comparative Example 2: Elution Gradient Investigation
[0138] Except for the elution gradient conditions described below, all other operations are the same as in Example 1.
[0139] Table 4
[0140]
[0141] Figure 6 The figure shows the high-performance liquid chromatogram of Yangxin Dawa Yimisik Honey Ointment in Comparative Example 2. As shown in the figure, the chromatogram of Comparative Example 2 shows some peaks with tailing, broadening, baseline drift, and high overall noise. Some chromatographic peaks have high overlap, indicating poor separation.
[0142] Comparative Examples 3-4: Investigation of Detection Wavelengths
[0143] Except for the following differences, all other operations are the same as in Example 1.
[0144] In Comparative Example 3, the detection wavelength was 210 nm. In Comparative Example 4, the detection wavelength was 360 nm.
[0145] According to the high performance liquid chromatogram of Yangxin Dawa Yimishike Honey Ointment in Comparative Example 3, at a wavelength of 210 nm, the peak elution time is too long, the response signal is weak, the separation is poor, and there are impurities, making it difficult to achieve complete separation of the chromatographic peaks.
[0146] According to the high performance liquid chromatogram of Yangxin Dawa Yimishike Honey Ointment in Comparative Example 4, at a wavelength of 360 nm, the number of visible chromatographic peaks is significantly reduced, the interference of impurity peaks is more significant, and the baseline noise is relatively large. This indicates that the detection specificity is poor and the signal-to-noise ratio is low at this wavelength, which is not conducive to the accurate identification and quantification of target compounds.
[0147] Therefore, the optimal detection wavelength for high-performance liquid chromatography (HPLC) is 254 nm during fingerprint pattern construction.
