Method for establishing evodia rutaecarpa liposoluble fingerprint and standard fingerprint thereof

A technology of fingerprint spectrum and Evodia Fructus resin, which is applied to the establishment of Evodia Fructus liposol fingerprint spectrum and the field of standard fingerprint spectrum, can solve the problems such as the inability to truly reflect the integrity of the efficacy of Evodia Fructus, and avoid the large absorption and absorption of near-ultraviolet impurity peaks. Good value and reproducible effect

Example Embodiment

[0040] Example of the present invention: the method for establishing the fat-soluble HPLC fingerprint of Evodia and the standard fingerprint of the fat-soluble components of Evodia

[0041] 1. Instruments and reagents

[0042] 1.1 Instrument

[0043] Agilent 1100 high performance liquid chromatograph; Agilent DAD detector; Agilent chromatography workstation.

[0044] 1.2 Test drug

[0045] Evodia, evodia olein, and evodia lactone, three reference substances were purchased from the National Institute for the Control of Pharmaceutical and Biological Products; acetonitrile, chromatographically pure; distilled water; syringe type microporous membrane filter, diameter 13mm, 0.45um; evodia medicinal materials

[0046] 2. Methods and results

[0047] 2.1 Selection of extraction method

[0048] The alkaloids in Evodia is one of the main components. In this experiment, we will try our best to extract the alkaloids while investigating the fat-soluble extraction conditions. Alkaloid extraction...

Abstract

The invention provides the establishment method of the lipid-soluble fingerprint diagram for the evodia and its standard fingerprint diagram which includes: making of the trying aqua, making of the comparing aqua, detecting by the HPLC, using fingerprint diagram software to treat the data and diagram and then get the lipid-soluble fingerprint diagram of the evodia. Compared with the existing technique, the invention is simple, stability, the precision is so much high and re-appear is good; The method to withdraw the lipid-soluble composition is brief and the time is short; the peak of lipid-soluble fingerprint diagram is many and the peak form is good, so it is easy to discriminate; The standard fingerprint diagram built up can be availably token by the quality of the evodia. Therefore, it provides a new standard for appraising the evodia.

Description

Technical field: [0001] The invention relates to a method for establishing fingerprints of Chinese medicinal materials, in particular to a method for establishing fingerprints of fat-soluble high-performance liquid chromatography (HPLC) of Evodia rutaecarpa, and a standard fingerprint of fat-soluble components of Evodia rutaecarpa obtained by the method. Background technique: [0002] Most of the traditional Chinese medicines and their preparations in my country lack strict quality standards and scientific testing methods, so it is difficult to effectively control their internal quality, cannot guarantee the safety and effectiveness of medication, and do not meet the requirements of the international pharmaceutical market, which seriously restricts the Chinese medicine industry in my country. development of. Strengthening the research on the quality control of traditional Chinese medicinal materials is a key issue in the standardization and standardization of traditional Chin...
