Problems solved by technology

[0003] At present, there is not yet a complete system for the analysis of the floral aroma substances of the entire Caryophyllaceae flowers in China and even in the world. Only foreign countries have reported methods for the separation and extraction of aroma substances from flowers in other genera of Caryophyllaceae. The aroma substance analysis system will have great theoretical and practical significance

Embodiment 1

[0020] This embodiment mainly adopts the organic solvent MTBE extraction technique (Lavy M etc., 2002)-gas chromatography-mass spectrometry of liquid sample injection to carry out qualitative and quantitative analysis of the endogenous aroma components in Carnation flowers, and the specific steps are as follows:

[0021] 1) Extract the endogenous aroma components in the flowers of the genus Dianthus:

[0022] Take 0.10 g of fresh petal samples ground into powder in liquid nitrogen, add 500 μL of ultrapure water, shake and mix well; After shaking and mixing, add 0.2-0.3g of anhydrous sodium sulfate to remove water, and shake and mix in a vortex for 2 minutes; at room temperature, centrifuge at 12000rmp for 2 minutes; take the upper organic phase with a disposable syringe, and collect it after passing through an organic filter In the sample bottle, to be tested.

[0023] 2) Using gas chromatography-mass spectrometry technology suitable for liquid sample injection to detect and ...

Abstract

The invention belongs to the technical field of plant component detection, and particularly relates to a separation and authentication method for endogenesis aroma components in dianthus chinensis flowers. The invention provides a separation and authentication method for the endogenesis aroma components in dianthus chinensis flowers, including dianthus chinensis, carnation, dianthus barbatus, dianthus superbus and the like. The method comprises the following steps that: utilizing an organic solvent MTBE (Methyl Tert Butyl Ether) extraction method to separate and collet the endogenesis aroma components in dianthus chinensis flowers, utilizing a gas chromatography-mass spectrometry to detect and analyze the exogenous volatile aroma substances of the dianthus chinensis flowers; and carrying out qualitative and quantitative analysis on the aroma components. In the qualitative analysis of detected endogenesis aroma components, unknown compounds are retrieved to be matched with an NIST (National Institute of Standards and Technology) MS (Mass Spectrometry) Search2.3 spectral database, the ingredients of parameters SI which is greater than 800 and RSI which is greater than 800 are taken to be qualitative, and the contents of the qualitative components are calculated according to an internal standard method. The separation and authentication method has the advantages of being convenient and quick in operation, wide in applicability and the like.

Description

technical field [0001] The invention belongs to the technical field of analysis and detection of plant components, and in particular relates to a method for separating and identifying endogenous aroma components in flowers of the genus Dianthus. Background technique [0002] There are about 600 species of flowers under the genus Dianthus. The common species include Chinese carnation, quince, carnation (carnation) and carnation, which are all widely planted and ornamental species under the genus Dianthus. Planting and cultivating Dianthus flowers can not only be viewed by people, but also extract essence and materials needed for making cosmetics. Therefore, the analysis of aroma components in Dianthus flowers will have huge application and economic value. [0003] At present, there is not yet a complete system for the analysis of the floral aroma substances of the entire Caryophyllaceae flowers in China and even in the world. Only foreign countries have reported methods for t...
