In addition, CN201210518917.1, CN102964228B, CN102964229B, CN201210518899.7, CN201210518963.1, CN201220666255.8, CN201220666403.6 respectively utilize complex steam distillation equipment to extract cinnamaldehyde, to still not improve the yield, but the efficiency
[0004] Take the solvent extraction method as an example, for example: China Taiwan No. 401394 patent, with methanol, CH containing ether 2 N 2 Organic solvent extraction such as solution, and then chloroform distribution extraction; Chinese Taiwan No. I495487 patent, by being selected from ethanol, propylene glycol, 1,3-butanediol, chloroform, dichloroethane, carbon tetrachloride, acetone, One or two or more extraction solvents of ethyl acetate and hexane are used for extraction; China Taiwan Patent No. I549686 continuously extracts cinnamon with methanol, and after three consecutive extractions, methanol extract is obtained. The methanol extract uses Methanol, water and n-hexane are used for partition extraction; CN201710245493.9 uses n-hexane as a solvent to extract cinnamon; but the disadvantage of these organic solvent extraction methods is that it is difficult to completely remove harmful organic solvents after extraction
[0005] Taking the supercritical carbon dioxide extraction method as an example, for example: China Taiwan No. I352611 patent, extracts the fat-soluble essential oil components in the cinnamon leaf fragments with supercritical carbon dioxide; but the extract obtained by the supercritical carbon dioxide extraction method has a main component of Essential oil, cinnamaldehyde content is low, and it is not easy to separate from essential oil

Embodiment 1

[0073] Leaves of Cinnamomum cassia were washed, dried, and then crushed into 1-10 mm pieces.

[0074] Weigh 350 grams of cinnamon leaf fragments, pour them into the extraction tank of the subcritical propane fluid extraction device, and then in order: determine the path of the pump, extraction tank, separation tank, etc. to empty the original air; inject propane with the same pressure as the propane storage tank (8 bar); set the extraction conditions as follows: propane flow rate 12 liters / hour, extraction tank pressure 45 bar / temperature 60°C, separation tank pressure 8-10 bar / temperature 50°C. Carry out propane subcritical extraction 2 hours with above-mentioned condition, obtain product 3.7 grams, its GC-MS collection of illustrative plates sees figure 1 , where the main components: cinnamaldehyde content of about 42%, the extraction rate of 86.3% (3.7x0.42 / 1.8); secondary components: o-methoxycinnamic aldehyde (o-methoxycinnamic aldehyde) about 11.2%, stearic acid formald...

Embodiment 2～13

[0079] Similar to Preliminary Example 1, but the subcritical extraction conditions are slightly different, see Table 2, and the amount of the obtained product is also shown in Table 2 below. Wherein the GC-MS collection of illustrative plates of preliminary embodiment 8,9,12,13 see respectively figure 2 , 3, 4, 5, wherein the cinnamaldehyde content is about 36-42%, and the yield is about 2.5-3.5g.

The method comprises the following steps: washing, drying and crushing cinnamon leaves into fragments; pouring the cinnamon leaf fragments into the SPE extraction tank of a subcritical propane fluid extraction device, and carrying out subcritical propane fluid extraction; introducing the extracted fluid into an SPE separation tank; and removing propane in the SPE separation tank to obtain a cinnamaldehyde composition; performing supercritical fractionation on the cinnamaldehyde composition, wherein the supercritical fractionation hardware at least comprises an SFF extraction tank, a first SFF fractionation tank, a second SFF fractionation tank and a third SFF fractionation tank, the subcritical propane fluid extraction conditions are that the pressure of the SPE extraction tank is 30-55 bar, and the temperature is40-75 DEG C, the supercritical fractionation conditions are that the pressure of the SFF extraction tank is 75-350 bar, and the temperature is 32-100 DEG C, the pressure of the first SFF fractionationtank is 74-250 bar and the temperature is 32-100 DEG C, the pressure of the second SFF fractionation tank is 45-200 bar and the temperature is 32-100 DEG C, and the pressure of the third SFF fractionation tank is 40-150 bar and the temperature is 5-100 DEG C.

Description

technical field [0001] The invention relates to the technical field of chemical extraction, in particular to a method and a device for extracting a composition rich in cinnamaldehyde from cinnamon leaves. Background technique [0002] Cinnamon root / bark / branch / leaf contains cinnamaldehyde, and the known extraction methods include water extraction, organic solvent extraction, and supercritical fluid extraction. [0003] Take the water extraction method as an example, for example: China Taiwan Patent Application No. 099114436, which is extracted with distilled water in a boiling state; Boil soil cinnamon leaves to obtain extract; China Taiwan Patent No. I494117, continuous distillation with steam distillation method to obtain water extract containing cinnamaldehyde; CN201610660116.7 extract with water vapor; but because cinnamaldehyde is a hydrophobic substance , so the extraction efficiency of these methods is not high, and the content of cinnamaldehyde in the extracted comp...
