Embodiment 1～18

[0046] After the red leaves in the snow are dried and removed, they are grinded by the FSJ-114 plant sample grinder, passed through a 40-mesh sieve, weighed 200 grams, and put into the extraction kettle of a 1 liter supercritical fluid extraction equipment for extraction. The crude extract of Xuezhonghong is obtained from the separation kettle, and the ethanol in it is rotary evaporated to obtain Xuezhonghong extract, which is weighed and the yield is calculated.

[0047] Yield=weight of Xuezhonghong extract (g) / weight of snowy red leaves (g)×100﹪

[0048] Among them, the weight of the red leaves in the snow is the dry weight without water.

[0049] The extraction conditions are as shown in Table 2:

[0050] Table 2 Extraction conditions and yields of Examples 1-18

[0051]

[0052]

[0053] Tests have proved that by using the process provided by the present invention, good yields can be obtained by performing supercritical fluid extraction on snow red leaves.

Embodiment 19

[0062] Example 19 GC-MS analysis of extract

[0063] After distilling the extracts prepared in Examples 1-18, the distillate was collected for GC-MS analysis.

[0064] The analysis adopts the 6890 / 5973N gas chromatography-mass spectrometer.

[0065] Chromatographic column: HP-5 (50m×0.25mm×0.50μm) capillary column; Carrier gas: Helium (He); Flow rate: 1mL / min; Injection volume 1μL; Injection port 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.

[0066] Among them, the detection pattern of the extract obtained in Example 18 is as follows: figure 1 Shown. 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...

Abstract

The invention relates to the field of plant component extraction, particularly a Xuezhonghong extract, and an extraction method and application thereof. The extract provided by the invention contains abundant terpenes, esters, acids and alcohols, most of which are volatile. The terpenes, esters, acids and alcohols endow the Xuezhonghong extract with intense aroma. The diluted extract has fresh and elegant aroma, and is suitable for daily chemical products. By extracting the Xuezhonghong leaves by supercritical fluid extraction, the method has the advantages of simple technique and no pollution, and the yield can each 8% or above.

Description

Technical field [0001] The present invention relates to the field of plant component extraction, and in particular relates to snow red extract and its extraction method and application. Background technique [0002] Xuezhonghong belongs to the genus Euonymus in the family Euonymus, and is a variant species of Hokkaido boxwood (also known as holly Euonymus, Dayleaf boxwood). In 2009, it was granted new plant variety rights. 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, and 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 vol...
