Problems solved by technology

[0004] However, there are few reports on the extraction of the essential oil of the fruit of the red thick shell. The essential oil of the fruit of the red thick shell contains components such as coumarins, xanthones, stearic acids, esters, and crab apple alcohol, which can be used to develop spices , medical health care products and other high-value products

Embodiment 1

[0013] 1. Dry the red thick-shelled fruit at low temperature and crush it into powder;

[0014] 2. Take 500g of crushed red thick-shelled fruit and put it into the extractor, and put supercritical CO 2 Pass it into it, add the entrainer ethanol to a volume of 50mL, set the extraction pressure to 25MPa, the temperature to 35°C, and set the CO 2 The outlet flow rate is 10mL / min, when the condition is reached, the timing starts, the extraction time is 120min, and the red thick shell supercritical fluid CO is collected. 2 Extract 2 grams;

[0015] 3. The red thick shell supercritical fluid CO 2 2 grams of the extract were dissolved in 20 mL of ethanol solution, and then evaporated to dryness under reduced pressure to obtain 1 gram of the essential oil component of red thick shell.

Embodiment 2

[0017] 1. Dry the red thick-shelled fruit at low temperature and crush it into powder;

[0018] 2. Take 500g of crushed red thick-shelled fruit and put it into the extractor, and put supercritical CO 2 Pass it into it, add the entrainer ethanol to a volume of 150mL, set the extraction pressure to 40MPa, the temperature to 60°C, and set the CO 2 The outlet flow rate is 50mL / min, when the condition is reached, start timing, the extraction time is 210min, and the red thick shell supercritical fluid CO is collected. 2 Extract 5 grams;

[0019] 3. The red thick shell supercritical fluid CO 2 5 g of the extract was dissolved in 50 mL of ethanol solution, and then evaporated to dryness under reduced pressure to obtain 2.05 g of the essential oil component of red thick shell.

Embodiment 3

[0021] 1. Dry the red thick-shelled fruit at low temperature and crush it into powder;

[0022] 2. Take 500g of crushed red thick-shelled fruit and put it into the extractor, and put supercritical CO 2 Pass it into it, add the entrainer ethanol to a volume of 100mL, set the extraction pressure to 35MPa, the temperature to 45°C, and set the CO 2 The outlet flow rate is 20mL / min, when the condition is reached, start timing, the extraction time is 150min, and the red thick shell supercritical fluid CO is collected. 2 Extract 4 grams;

[0023] 3. The red thick shell supercritical fluid CO 2 4 g of the extract was dissolved in 35 mL of ethanol solution, and then evaporated to dryness under reduced pressure to obtain 2.4 g of the essential oil component of the red thick shell.

Abstract

The invention relates to an extraction method of calophyllum inophyllum linn essential oil components, which comprises the following steps: 1. drying calophyllum inophyllum linn fruits at low temperature, and crushing the calophyllum inophyllum linn fruits to be powder; 2. placing the calophyllum inophyllum linn powder in an extraction kettle, adding 0.1-0.3 time of entrainer ethanol by weight, setting the outlet flow of CO2 of supercutical fluid to be 10-50mL / min under the conditions of 25-40MPa of pressure and 35-60 DEGC of temperature, extracting the power added with the entrainer ethanol for 120 min-210 min, collecting and obtaining the extract of the calophyllum inophyllum linn supercutical fluid CO2; 3. dissolving the extract of the calophyllum inophyllum linn supercutical fluid CO2 into the ethanol solution with the weight being 5-10 times of that of the calophyllum inophyllum linn supercutical fluid CO2, and depressurizing and steaming to obtain the calophyllum inophyllum linn essential oil containing coumarin, genocide, stearic acid and ester. The invention has simple operation and high extraction ratio (which can reach 0.2-0.48 percent), and can be used for developing high-value product of perfume, medical health products, and the like because the extracted calophyllum inophyllum linn essential oil mainly contains the components of the coumarin, the genocide, the stearic acid, the ester, and the like.

Description

technical field [0001] The present invention relates to the extraction method of the essential oil composition of red thick shell, especially a kind of extraction method that adopts supercritical CO 2 Extraction process The method of extraction. Background technique [0002] Red thick shell (Calophyllum inophyllum Linn), also known as Chinese crabapple, Chinese crabapple, crabapple, gentleman tree, crabapple wood, Qiongzhou crabapple, is an evergreen tree of the genus Calophyllum genus of Guttiferae (Guttiferae), distributed in my country It is found in Hainan, Guangdong, Guangxi, Taiwan and other provinces, as well as in tropical regions such as Southeast Asia, South Asia and Africa. The red thick-shelled plant has high medicinal value, and it is often used as antiseptic, antibacterial, astringent, expectorant, diuretic and laxative in the folk. The fruit and seeds of the red thick shell are rich in oil. The oil of the seeds and roots can cure wounds and scabies, and intra...
