Embodiment 1～11

[0039] After drying and removing impurities, the red leaves in the snow were ground by FSJ-114 plant sample grinder, weighed 20g, put them into a Soxhlet extraction tube, added 300mL solvent for Soxhlet extraction, dried the distillate, and rotary evaporated petroleum ether or ethanol and then weighed. Calculate the yield of Xuezhonghongye extract.

[0040] Extraction yield = Xuezhonghong extract weight (g) / Xuezhonghong leaf weight (g) × 100﹪

[0041] Among them, the weight of red leaves in the snow is the dry weight after removing water.

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

Embodiment 1～18

[0043] Table 2 Example 1~18 extraction conditions and yield

[0044]

[0045] Example 4

[0046] Tests have proved that good yields can be obtained by using the process provided by the invention to perform Soxhlet extraction on the leaves of Xuezhonghong.

Embodiment 12

[0047] Example 12 extract GC-MS analysis

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

[0049] The analysis uses 6890 / 5973N gas chromatography-mass spectrometry.

[0050]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: 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 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 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, in particular to the extract of eucalyptus 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 the control variet...
