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.
