Embodiment 1～11

[0039] After the red leaves in the snow are dried and removed, they are grinded by a FSJ-114 plant sample grinder, weighed 20g, put into a Soxhlet extraction tube, added 300mL solvent for Soxhlet extraction, the distillate is dried, and the petroleum ether is rotary evaporated Or weigh after ethanol. Calculate the yield of Xuezhonghongye extract.

[0040] Extraction rate = Xuezhonghong extract weight (g) / Xuezhonghong leaves weight (g)×100﹪

[0041] Among them, the weight of the red leaves in the snow is the dry weight without water.

[0042] The extraction conditions are as shown in Table 2:

[0043] Table 2 Extraction conditions and yields of Examples 1-18

[0044]

[0045] Example 4

[0046] Tests have proved that using the process provided by the present invention, the Soxhlet extraction of the red leaves of the snow can obtain good yields.

Embodiment 12

[0047] Example 12 GC-MS analysis of extract

[0048] After distilling the extracts prepared in Examples 1-11, the distillate was collected for GC-MS analysis.

[0049] The analysis adopts the 6890 / 5973N gas chromatography-mass spectrometer.

[0050] Chromatographic column: HP-5 (50m×0.25mm×0.50μm) capillary column; carrier gas: helium (He); flow rate: 1mL / min; injection volume 1μL; inlet temperature 280℃, split ratio 1: 20. Column temperature program: starting temperature at 50℃, keep for 5min, then increase to 260℃ at a rate of 5℃ / min, keep for 10min; ion source temperature: 250℃, ionization mode: EI; electron energy: 70eV; mass scanning range: 33~550amu.

[0051] By comparing the mass spectrum data of volatile flavor substances with the data in the computer standard spectral library NIST02, qualitative and quantitative analysis of various volatile components is carried out. The results are shown in Table 3:

Abstract

The invention relates to the field of plant component extraction and especially relates to Euonymus japonicus Thunb. extract and its preparation method and use. The Euonymus japonicus Thunb. extract contains a lot of terpenes, esters, acids and alcohols and most of the above substances have volatility. The above substances provide an intense fragrance for the Euonymus japonicus Thunb. extract. Through dilution, the Euonymus japonicus Thunb. extract has a refreshing and light smell and is suitable for daily chemical products. Through a Soxhlet extraction method, the Euonymus japonicus Thunb. extract is extracted from Euonymus japonicus Thunb. leaves. The preparation method has simple processes, no pollution and a yield of 6% or more.

Description

Technical field [0001] The invention relates to the field of plant component extraction, and in particular to a snow red extract and a preparation method and application thereof. Background technique [0002] Xuezhonghong is a plant of the genus Euonymus in the family Euonymus, and is a variant species of Hokkaido boxwood (also known as Holly Euonymus, Dayleaf boxwood). It was granted the right to new plant varieties in 2009. The red leaves in the snow are nearly round, with shallow wavy leaf edges, full opposite leaf buds, axillary cymes, light yellow-green flowers, sub-spherical capsules, light green when the fruit is tender, brownish red on the sunny side, and mature fruits light yellow. The leaf color of "Xuezhonghong" is three-season green and red in winter. The leaf shape is thicker and rounder without variation. The amount of fruit hanging is more than 20 times larger than that of the original species. , The amount of fruit hanging is average [0003] Plants contain volat...
