Embodiment 1

[0026] Pulverize the yellow skin kernels sold in pharmacies, pass through a 60-mesh sieve, extract 1.5 kg with supercritical carbon dioxide, extract at a pressure of 25 MPa, and a temperature of 30 ° C; extract at a pressure of 10 MPa and at a temperature of 20 ° C; obtain 60 ml Extracts;

[0027] Add 30 milliliters of ethanol to dissolve the extract, then add 270 milliliters of water and leave it for a day and night to obtain crystalline substances, which have crystals of different colors such as white or yellow. The above mixed crystals were detected by GC / MS, and it was confirmed that they contained the aforementioned five kinds of cinnamonamides, the total content of which exceeded 90%.

Embodiment 2

[0029] Commercially available yellow skin cores were pulverized, passed through a 100-mesh sieve, and extracted with 2 kg of supercritical carbon dioxide. The pressure of the extraction kettle was 30 MPa, and the temperature was 40 ° C; the pressure of the separator was 15 MPa, and the temperature was 30 ° C, to obtain 80 ml g of extract;

[0030] Add 60 milliliters of ethyl acetate to uniformly disperse and dissolve the extract, then add 30 milliliters of water and let it stand for 2 days. In the water phase, there are crystalline substances and crystals of different colors such as white or yellow. Continue to use as a solvent.

Embodiment 3

[0032] Commercially available yellow skin cores were pulverized, passed through a 100-mesh sieve, and extracted with 1.5 kg of supercritical carbon dioxide. The pressure of the extraction kettle was 40 MPa, and the temperature was 50 ° C; the pressure of the separator was 20 MPa, and the temperature was 40 ° C; 60 ml g of extract was obtained;

[0033] Add 120 ml of chloroform to disperse the extract evenly, filter to remove insoluble matter, add 60 ml of water to the filtrate, remove the water phase, and place it at room temperature for 7 days, wait for the chloroform to slowly volatilize, and obtain crystalline substances in the chloroform phase , There are crystals of different colors such as white or yellow.

Abstract

This invention relates to a wampee core extract and preparation method. It is extracted from wampee core, mostly maintain N - methyl - cinnamyl amine, N - methyl - N - cis form - phenethyl - cinnamyl amine, N - methyl - N - cis form -styryl - cinnamyl amine, N - methyl - N - transform - phenethyl - cinnamyl amine and N - methyl - N - transform -styryl- cinnamyl amine. The total content of these above five kinds cinnamyl amine exceed 90 percent. This wampee core extract possess type fragrance of wampee, useful for flavour treating; it adopts above-critical carbon dioxide extraction technology for extracting, extract has high effective ingredient content; the raw material wampee core is abundance and cheap, so the cost is low; Changing wastes into valuables as well as preventing environmental pollution.

Description

technical field [0001] The invention relates to cinnamon amide compounds, in particular to a cork kernel extract and a preparation method thereof. Background technique [0002] The yellow skin core is also called the yellow skin fruit core, which is the dry seed of the yellow skin fruit [Ciausena lansium (Lour.) Skeels], which is flat oval, 11-14 mm long, 8-9 mm wide, and 3-4 mm thick ; the apex is slightly pointed and slightly bent to one side, the base is round and blunt, the base 1 / 3 is brown, more slippery than nails, the upper 2 / 3 is brownish yellow, with irregular wrinkles; the hilum is located at the apex, nearly elliptic; chalaza Located at the base, on the same side as the hilum; the hilum is slightly protruding, leading from the hilum to the chalaza; the seed coat is thin and brittle, and often breaks off; two cotyledons, earthy yellow, thick, brittle, easy to break, and flat in section; Embryo very small, without endosperm. Mainly produced in southern China. Th...
