example 1

[0019] 1. Amomum powder mixed with 4 times the volume of 95% ethanol, soaked for 15 minutes;

[0020] 2. Under the conditions of temperature 60°C and microwave power 200W, use dynamic microwave extraction equipment to process the above mixture for 13 minutes, and collect the filtrate after vacuum filtration;

[0021] 3. Take the filter residue and add 4 times the volume of 95% ethanol to extract according to step 2, repeat twice, and combine the filtrate;

[0022] 4. Concentrate the combined filtrate by distillation under reduced pressure at 0.09MPa until no solvent flows out.

[0023] The yield of Amomum oleoresin extracted by the above method is 8.2%. Gained Amomum oleoresin further adopts gas chromatography-mass spectrometry to analyze the aromatic components therein, and the results are as shown in Figure 1, the top four compounds with the highest content are successively: the compound with retention time at 15.70 is (±)-camphor, The relative content reaches 48.12%; the ...

example 2

[0025] 1. Amomum powder mixed with 4 times the volume of 95% ethanol, soaked for 10 minutes;

[0026] 2. Under the conditions of temperature 78°C and microwave power 300W, use dynamic microwave extraction equipment to process the above mixture for 8 minutes, and collect the filtrate after vacuum filtration;

[0027] 3. Take the filter residue and add 3 times the volume of 95% ethanol to extract according to step 2, repeat twice, and combine the filtrate;

[0028] 4. Concentrate the combined filtrate by distillation under reduced pressure at 0.01 MPa until no solvent flows out.

[0029] The yield of Amomum oleoresin extracted by the above method is 8.7%. Gained Amomum oleoresin is further analyzed by gas chromatography-mass spectrometry, wherein the relative content of (±)-camphor reaches 50.22%, the relative content of bornyl acetate is 34.35%, the relative content of R-syringene is 3.45%, and the relative content of borneol is 1.11%.

example 3

[0031] 1. Amomum powder mixed with 5 times the volume of 95% ethanol, soaked for 20 minutes;

[0032] 2. Under the conditions of temperature 40°C and microwave power 100W, use dynamic microwave extraction equipment to process the above mixture for 13 minutes, and collect the filtrate after vacuum filtration;

[0033] 3. Take the filter residue and add 5 times the volume of 95% ethanol to extract according to step 2, repeat twice, and combine the filtrate;

[0034] 4. Concentrate the combined filtrate by distillation under reduced pressure at 0.03 MPa until no solvent flows out.

[0035] The yield of Amomum oleoresin extracted by the above method is 6%. Gained Amomum oleoresin is further analyzed by gas chromatography-mass spectrometry, wherein the relative content of (.±)-camphor reaches 45.66%, the relative content of bornyl acetate is 33.21%, the relative content of R-syringene is 7.21%, and the relative content of borneol was 3.11%.

Abstract

The present invention provides alcohol and microwave extracting process of amomum oil resin from amomum fruit. The extracting process has high extracting rate, amomum oil resin yield up to 6-8.7 %, and high amomum oil resin purity, and the extracted amomum oil resin has (+ / -)-camphor, borneol acetate, R-caryophyllene and borneol accounting for over 90 % of its aromatic components.

Description

technical field [0001] The invention relates to a method for extracting fat from plants, in particular to a method for extracting oleoresin. Background technique [0002] Amomum villosmn Lour., also known as Amomum villosmn Lour., is the fruit of the genus Cardamom in the family Zingiberaceae. Antiemetic function; as an aromatic food raw material, it is used not only as a seasoning spice, but also as a health food. Amomum is rich in aromatic components of monoterpenes and sesquiterpenes, of which bornyl acetate, (±)-camphor and borneol are the main components; R-syringene, cobalene and other aromatic components are also high, nearly 60 Two detectable aromatic components constitute the unique flavor of amomum. [0003] At present, there are three main methods for extracting the effective components of Amomum sativa: 1. Steam distillation: steam distillation is difficult to obtain complete aromatic components due to higher temperature and longer time. Due to the limitation o...
