Embodiment 1

[0034] The invention provides a method for determining the content of magnolol and its honokiol in Huoxiangzhengqi water, which sequentially includes the following steps:

[0035] 1) Preparation of reference solution:

[0036] Take an appropriate amount of magnolol and honokiol reference substance, accurately weigh them, respectively add methanol to make a solution containing 0.2mg of magnolol and 0.1mg of magnolol per 1ml, shake well, and get it;

[0037] 2) Preparation of test solution:

[0038] Accurately measure 5ml of this product, add 2 drops of hydrochloric acid, shake and extract 3 times with chloroform, 10ml each time, combine the chloroform solution, evaporate to dryness, dissolve the residue with methanol and transfer to a 10ml measuring flask, add methanol to Graduation, shake well, filter, take additional filtrate;

[0039] 3) Precisely draw 10μl each of the reference solution and the test solution, inject into the liquid chromatograph, and measure, and it is obtained;

Abstract

The invention discloses a mangnolia officinalis content assaying method for ageratum liquid and aims to provide a magnolol and honokiol content assaying method for ageratum liquid which is short in analysis time and high in operation efficiency. The mangnolia officinalis content assaying method is characterized by including 1) preparing control solution; 2) preparing test solution; 3) precisely sucking 10 microliters of the control solution and the test solution respectively, injecting the solution into a liquid chromatograph, assaying and acquiring the content. The chromatographic conditions include that the instrument employs high-performance liquid chromatograph Agilent 1290, chromatographic column is Thermo Syncroins aQ 50*2.1 mm 1.7 micrometers, mobile phase is methyl alcohol and water at the ratio of 58 to 42, flow velocity is 0.3 ml/min, and detection wavelength is 294 nm. The mangnolia officinalis content assaying method belongs to the technical field of medical examination.

Description

Technical field [0001] The invention relates to a method for determining the water content of Huoxiangzhengqi water, in particular to a method for determining the content of magnolol and its honokiol in Huoxiangzhengqi water, and belongs to the technical field of medical detection. Background technique [0002] Huoxiang Zhengqi Water is made of atractylodes, tangerine peel, magnolia officinalis, angelica dahurica, poria cocos, belly bark, raw pinellia, licorice extract, patchouli oil, perilla leaf oil, and the auxiliary material is ethanol; it has the function of relieving surface and removing dampness and regulating qi Hezhong, used for colds caused by exogenous wind-cold, internal injury and dampness or summer heat and dampness. Symptoms include headache, dizziness, chest and diaphragm tightness, abdominal distension and pain, vomiting and diarrhea; gastrointestinal colds with the above syndromes. [0003] In order to ensure the quality of the product, it is usually necessary to ...
