Embodiment Construction

[0034] The present invention will be further described below in conjunction with specific examples, but the present invention is not limited.

[0035] 1. Materials

[0036] 1.1 Instrument

[0037] Agilent 6890-5975 Gas Chromatograph-Mass Spectrometer, HB-5 Capillary Column

[0038] (30m×0.25μm×0.25μm), sample tube, water bath, separatory funnel.

[0039] 1.2 Sample

[0040] Angelica dahurica samples were produced in Sichuan.

[0041] 2. Method

[0042] 2.1 Extraction of volatile oil

[0043] Put 20g of Angelica dahurica in a volatile oil extractor, add 10 times the sample amount of double distilled water to soak for 12 hours, and reflux for 5 hours until the distillate has no obvious oil droplets. Transfer the distillate to a separatory funnel, extract twice with 60 mL of diethyl ether, combine the extracts, dry with anhydrous sodium sulfate, and then evaporate the diethyl ether in a water bath at 50°C to obtain the volatile oil of Angelica dahurica.

Abstract

The invention discloses a method for analyzing GC / MS (Gas Chromatography / Mass Spectrography) finger-print of composition in essential oil of angelica dahurica, which comprises the following steps of: (1) extracting the essential oil; (2) performing GC / MS analysis of the chemical composition in the essential oil of the angelica dahurica; (3) confirming a GC / MS total ion current profile of the essential oil and quantifying relative content of the composition by employing a peak area normalization method; (4) establishing the finger-print; and (5) methodologically inspecting the finger-print. According to the method disclosed by the invention, an optimal extraction method for the essential oil of the angelica dahurica is definitely determined, the gas chromatography condition and the mass spectrography condition are optimized and selected, and the GC / MS finger-print of the essential oil of the angelica dahurica is established, so that the chemical compositions and the proportions thereofin the primary volatile elements of the angelica dahurica are reflected and the quality of the essential oil of the angelica dahurica is effectively represented; and the GC / MS finger-print of the essential oil of the angelica dahurica established by the method provided by the invention also has good reproducibility and reliability, so that a reliable way is provided for quality control and production place identification of the essential oil of the angelica dahurica.

Description

technical field [0001] The invention relates to the field of analysis and testing of the traditional Chinese medicine Angelica dahurica, in particular to an analysis and detection method for the volatile oil components of Angelica dahurica. Background technique [0002] Angelica dahurica was first recorded in "Shen Nong's Materia Medica", and it is one of the traditional Chinese medicines. It is the dried root of Angelica dahurica or Angelca dahurica var. formosana. Angelica dahurica is the mainstream variety of commercial medicinal materials of Angelica dahurica, accounting for about 70% of the output of commercial Angelica dahurica in China. Angelica dahurica is warm in nature and pungent in taste. It has the functions of dispelling wind and cold, drying dampness, draining pus, and relieving pain. It is used for wind-cold cold, headache, rhinitis, toothache, etc. Angelica dahurica contains volatile oil, coumarin and its derivatives, such as angelica, white angelica ether,...
