Problems solved by technology

[0003] Experimental studies have shown that the volatile components in the antiviral oral liquid have anti-inflammatory, antiviral, antipyretic and other effects, but among the existing standard quality control items, the only control item for the volatile components of this variety is bocicol (derived from Patchouli) qualitative identification, the evaluation of product quality is not comprehensive enough, and there is a problem that the quality standard is too low

Embodiment 1

[0043] A method for detecting volatile components of antiviral oral liquid, comprising the following steps:

[0044] (1) Sample pretreatment.

[0045] The volatile components in the sample to be tested are extracted by steam distillation, and the specific steps are as follows:

[0046] Precisely measure 100ml of the sample to be tested (finished antiviral oral liquid), put it in a 500ml round bottom flask, add 100ml of water and a few zeolite grains, connect the volatile oil detector, add water from the upper end of the detector to fill the scale part, and overflow into the flask until , then add 2-3ml of cyclohexane, connect the reflux condenser, heat and reflux for 2 hours, cool, take the cyclohexane solution layer, put it in a 5ml measuring bottle, and precisely add 0.5ml of n-nonadecane with a concentration of 1.5mg / ml The internal standard solution was diluted to the mark with cyclohexane, and shaken to obtain the sample solution.

[0047] (2) Preparation of volatile co...

Abstract

The invention relates to a detection method for volatile components in antiviral oral-liquid and belongs to the technical field of pharmaceutical analysis. The method comprises the following steps: extracting volatile components of a to-be-detected sample by adopting a steam distillation method, an extracting method, or an organic solvent reflux extracting method, and preparing a sample solution; finely weighing alpha-pinene, beta-pinene, terpinene-4-alcohol, terpilenol, borneol, methyleugenol, patchouli alcohol, beta-asarone, patchoulenone, and alpha-asarone, and preparing volatile component reference solutions by using an organic solvent; and determining the ten types of volatile components by using a gas chromatography simultaneously, so that medicinal material information can be relatively completely reflected, the product quality is relatively completely evaluated, the quality standard is increased, and simultaneously conditions are provided for the product manufacturing technique optimization.

Description

technical field [0001] The invention relates to the technical field of drug analysis, in particular to a method for detecting volatile components of an antiviral oral liquid. Background technique [0002] The antiviral oral liquid is currently listed in the 2015 edition of the "Chinese Pharmacopoeia". The solution has the effects of clearing away heat and dampness, cooling blood and detoxifying, and is used for anemopyretic cold, fever due to febrile disease, upper respiratory tract infection, influenza, mumps and other viral infection diseases. [0003] Experimental studies have shown that the volatile components in the antiviral oral liquid have anti-inflammatory, antiviral, antipyretic and other effects, but among the existing standard quality control items, the only control item for the volatile components of this variety is bocicol (derived from Patchouli), the quality evaluation of the product is not comprehensive enough, and there is a problem that the quality standa...
