Problems solved by technology

[0003] At present, there are few domestic reports on the aroma components of rose water. Rhododendron et al. have captured and enriched the aroma components in rose water in Kashgar, Xinjiang through static adsorption, secondary distillation, and solvent extraction. Among them, the secondary The enrichment effect of the distillation method is the most ideal, and a total of 22 kinds of aromatic components remaining in the rose water are obtained, but it takes a long time to process the sample by the second distillation method; The aroma of rose water was extracted and enriched, the main aroma components of the flower water obtained from May to July were analyzed and compared, and their quality was evaluated. The composition of the flower water was different in different months, but the macroporous resin adsorption method The pre-extraction treatment cycle is longer and more rose water is used, which will cause a lot of waste of rose water
At present, there is no report on the analysis and quantification of the aroma components of Chinese Kushui rose flower water

Embodiment 1

[0036] The standard spices in this example were all purchased from Dr. Ehrenstorfer; dichloromethane and ethanol were chromatographically pure and purchased from Merck KGaA.

[0037] (1) Sample treatment: Take the rose water obtained by steam distillation from the Kushui rose planted in Yongdeng County, Gansu Province, and collect it in a sealed bottle; accurately pipette 15mL of rose water sample into a 50mL centrifuge tube, add 5mL Dichloromethane, vortex for 2 minutes, centrifuge for 5 minutes in a high-speed refrigerated centrifuge at a speed of 13,000 r / min, and then take the dichloromethane layer into a sample injection vial.

[0038] (2) Qualitative analysis of the volatile aroma components of Kushui rose flower water sample:

[0039] The dichloromethane layer is carried out gas chromatography-mass spectrometry analysis, wherein the gas chromatography-mass spectrometry instrument (U.S. Agilent Company), model Agilent 7890A / 5975C; the chromatographic condition of gas chr...

Embodiment 2

[0061] Using the method of Example 1, the rose water samples collected from different manufacturers were tested. The sample numbers were 1-5. The results of the test are shown in Table 3.

[0062] Table 3 actual sample measurement results

[0063]

[0064] As can be seen from Table 3, citronellol and benzyl alcohol are the main components in the Kushui rose water produced by No. 1 factory, and the Damascus rose water produced by No. 2 factory uses phenylethyl alcohol as the main component, and the content is relatively high, which is similar to According to foreign reports, No. 3, No. 4 and No. 5 are all purchased from different brands of rose lotion. The manufacturers are different, and the content of aroma components is also different.

Abstract

The invention provides an analysis method of aroma components in Grievances rose water. The method comprises the following steps: extracting and enriching aroma components in Grievances rose water bytaking dichloromethane as an extraction solvent, and then orderly performing qualitative and quantitative analysis through gas chromatography-mass spectrometry (GC / MS) and gas chromatography. The analysis method provided by the invention is simple and convenient, high in sensitivity, and low in cost, capable of satisfying the demands of quickly determining eight feature aroma components in the Grievances rose water, and suitable for high-flux analysis of large batch of samples; and an effective authentication method is provided for adulteration analysis of the Grievances rose water.

Description

technical field [0001] The invention relates to the technical field of analysis and detection, in particular to an analysis method for the aroma components in the water of bitter water roses. Background technique [0002] The Chinese Kushui rose, which is mainly produced in Yongdeng County, Gansu Province, is a hybrid of Chinese rose and Rosa blunt tooth. After more than 200 years of cultivation, it has formed the famous "Kushui rose" brand. It is characterized by juicy flowers, pure fragrance, and bitter water The town also enjoys the reputation of "the first town of roses in China". Rose water is distilled and extracted from roses and contains a small amount of rose essential oil. A moderate amount of rose water has anti-aging effects. At present, there are no processing technology standards for rose water in China, and there are no industry standards or national standards for products. Therefore, the qualitative and quantitative analysis of the characteristic aroma comp...
