Embodiment 1

[0027] Gas chromatography conditions:

[0028] Chromatographic column: HP-INNOWax capillary column (60m×0.25mm×0.25μm)

[0029] The inlet temperature is 250°C, and the detector temperature is 250°C;

[0030] The carrier gas is high-purity nitrogen, the flow rate is 0.5ml / min, and the split ratio is 100:1;

[0031] Temperature program: the initial temperature is 80°C, keep for 5 minutes, increase to 220°C at a rate of 2°C / min, and keep for 20 minutes; the injection volume is 0.2 μL.

[0032] After the instrument stabilizes, the error of three continuous injection needles is less than 1%, and the average value is taken to calculate the content of the main components in Pingyin rose essential oil. The calculation formula is as follows: X%=A / ∑Ai×100%, in the calculation formula, X% is the content percentage of a certain component in Pingyin rose essential oil; A is the peak area of ​​a certain component in the chromatogram; ΣAi is the peak area of ​​all peaks in the chromatogram...

Abstract

A Pingyin rose essential oil GC chromatographic method comprises the following steps: dissolving Pingyin roses into n-hexane, injecting n-hexane into a gas chromatograph, wherein the gas chromatography detection conditions are as follows: chromatographic column: HP-INNOWax elastic capillary column, injection port temperature: 250 DEG C, detector temperature: 250 DEG C, carrier gas: nitrogen, flow velocity: 0.5 mL / min, and split ratio: 100:1; carrying out temperature programming: maintaining the primary temperature (80 DEG C) for 5 minutes, raising the temperature to 220 DEG C at a speed of 2 DEG C / min, maintaining the temperature for 20 minutes; wherein the injection amount is 0.2 [mu]L, the appearance time of citronellol is 47.917 minutes, the appearance time of nerol is 49.653 minutes, and the appearance time of geraniol is 52.061 minutes; after the instrument becomes stable, calculating the contents of main components of Pingyin rose essential oil. The provided method can accurately measure the main components and contents of Pingyin rose essential oil. Moreover, the service life of the chromatographic column is long.

Description

technical field [0001] The invention belongs to the technical field of chemical analysis, and relates to a Pingyin rose essential oil, in particular to a GC chromatographic analysis method for Pingyin rose essential oil. Background technique [0002] Rose essential oil is a volatile oil obtained by steam distillation of the flowers of the Rosaceae plant rose. It is a colorless or yellow liquid with a rose fragrance. The main ingredients are citronellol, geraniol, nerol, phenylethyl alcohol, linalool, rose ether, etc. Its aroma is sweet, rich and plump, and it is the crown of flower oils, and it is one of the important flower essential oils. [0003] Pingyin rose has a long history and excellent quality. It is a unique high-quality rose variety. Pingyin rose is well received at home and abroad for its fragrant, rich and pure aroma. Precious Chinese medicinal materials and important raw materials for spice industry and food industry. [0004] At present, there are many tech...
