Embodiment 1～11

[0042] After drying and removing impurities, the red leaves in the snow were ground by a FSJ-114 plant sample grinder, weighed 50g, placed in a 1000mL round bottom flask, and soaked in 400mL of water. After soaking, install a volatile oil extractor and a spherical condenser, heat and reflux for 4 hours, extract the distillate, dry it with anhydrous sodium sulfate, evaporate the petroleum ether and weigh it. Calculate the yield of essential oil of red leaves in snow.

[0043] Essential oil yield = weight of Xuezhonghong essential oil (g) / weight of Xuezhonghong leaves (g) × 100﹪

[0044] Among them, the weight of red leaves in the snow is the dry weight after removing water.

[0045] The extraction conditions are as shown in Table 2:

[0046] Table 2 Example 1~11 extraction conditions and yield

[0047]

[0048] It has been proved by experiments that, by adopting the process provided by the invention, good yields can be obtained even if the steam distillation and extractio...

Embodiment 12

[0049] Example 12 extract GC-MS analysis

[0050] The essential oils prepared in Examples 1-11 were analyzed by GC-MS.

[0051] The analysis uses 6890 / 5973N gas chromatography-mass spectrometry.

[0052] Chromatographic column: HP-5 (50m×0.25mm×0.50μm) capillary column; carrier gas: helium (He); flow: 1mL / min; injection volume 1μL; inlet temperature 280°C, split ratio 1: 20. Column temperature program: initial temperature 50°C, keep for 5min, then increase to 260°C at a rate of 5°C / min, keep for 10min; ion source temperature: 250°C, ionization mode: E I; electron energy: 70eV; mass scanning range: 33~550amu.

[0053] By comparing the mass spectrum data of volatile flavor substances with the data in the computer standard spectrum library NIST02, the qualitative and quantitative analysis of various volatile components was carried out. The results are shown in Table 3:

Abstract

The invention relates to the field of essential oil extraction, in particular to Euonymus japonicus essential oil and a preparing method and application thereof. The Euonymus japonicus essential oil contains a large amount of terpene matter, a large amount of ester matter, a large amount of acid matter and a large amount of alcohol matter, and most of the matter is volatile. The Euonymus japonicus essential oil has the fresh and quiet flavor through the combination of all the matter, the flavor can relieve nerves, and the Euonymus japonicus essential oil is suitable for daily cosmetics. Extraction is conducted on Euonymus japonicus leaves through the steam distillation method. The technological method is simple, pollution is avoided, and the yield can reach 0.2%.

Description

technical field [0001] The invention relates to the field of essential oil extraction, in particular to the essential oil of eucalyptus essential oil and its preparation method and application. Background technique [0002] Xuezhonghong is a plant of the genus Euonymus in the family Euonymus, a variant variety of Hokkaido Boxwood (also known as Holly Euonymus, Euonymus euonymus), and was granted the right of new plant variety in 2009. The leaves of Xuezhonghong are nearly round, the leaf margins are shallow wavy, the leaf buds are full and opposite, the cymes are axillary, the flowers are light yellow-green, the fruit is a sub-spherical capsule, the fruit is light green when tender, and the sunny side is brownish red. light yellow. The leaf color of "Xuezhonghong" is green in three seasons and red in winter. The shape of the leaves is thicker and rounder, without variation, and the fruit-bearing capacity is more than 20 times that of the original species. The leaf color of ...
