Embodiment 1

[0109] A kind of detection method of volatile component in mugwort oil, described detection method comprises the following steps:

[0110] (1) Qualitative analysis:

[0111] (1) Take 0.2 g of the test product supercritically extracted molecularly distilled mugwort oil, accurately weigh it and place it in a conical flask, add 20 ml of methanol with a mass fraction of 70 to 100%, seal and shake to dissolve it, and use a 0.22 μm microporous filter Membrane filtration, to obtain the test product stock solution; accurately draw 1ml of the test product stock solution, place it in a 10ml volumetric flask, dilute to the mark with methanol, shake well and filter, to obtain the test product on-machine solution.

[0112] (2) Measure 1 μl of the sample solution to be tested for gas chromatography-mass spectrometry detection, and obtain the chromatogram-mass spectrum in the full-scan "Scan" mode and the chromatogram-mass spectrum in the "SIM" mode;

Embodiment 2

[0163] In this embodiment, the quantitative detection method of each main volatile component is the same as that in Example 1, except that the mugwort oil for testing is a commercially available certain mugwort essential oil.

[0164] The content detection result of each main volatile component in the present embodiment's test product mugwort oil is as follows:

[0165]

Embodiment 3

[0167] In this embodiment, the qualitative and quantitative detection methods of the main volatile components are the same as in Example 1 except that the test products are methanol solution and mugwort oil used for preparing standard solution series and diluted samples. By comparison, it can be seen that the methanol response value of the reagent blank solution is lower than 1000 counts, which does not interfere with the qualitative and quantitative analysis of the mugwort oil samples.

[0168] Figure 12 Prepare the gas chromatography-mass spectrogram of the used methanol of standard solution series and diluted sample for this embodiment;

Abstract

The invention provides a method for detecting volatile components in Artemisia argyl oil, and application thereof, and relates to the technical field of volatile component detection. The detection method is used for detecting the the volatile components in the Artemisia argyl oil through a gas chromatography-mass spectrometry detection technology. A spectrum library retrieval technology is used for carrying out retrieval qualitation on a chromatographic mass spectrogram in a full-scanning Scan mode to obtain qualitative data of all volatile components; and meanwhile, the peak area of the chromatographic mass spectrogram of the main volatile substances is analyzed in the SIM mode by using a segmented scanning technology, and the content of each main volatile substance is further calculatedby using an external standard method. The method has the characteristics of simplicity, accuracy, specificity and high practicability.

Description

technical field [0001] The invention relates to the technical field of volatile component detection, in particular to a method for detecting volatile components in mugwort oil and its application. Background technique [0002] Artemisia argyi is an early plant recognized and used by medical scientists in my country. It is recorded in "Book of Songs" and "Huangdi Neijing"; "(Part), "White Artemisia" or "White Artemisia" described in ancient herbal books, most of the plants of its terrestrial species actually include this species and its close relatives, such as Artemisia broadleaf A.stolonif era ( Maxim.) Komar, A.gilvescens Miq., A.lavandulaefoliaDC., A.verlotorum Lamotte, A.leucophylla(Turcz.ex Bess.)C.B.Clarke, A.mongolica (Fisch.ex Bess.) Nakai, A. rubripes Nakai, A. indico Willd., A. princeps Pamp. and A.igniaria Maxim. and other "composite species" name. In recent years, with the extensive research on wormwood, studies have shown that the basis of its medicinal effects c...
