Abstract
The invention discloses an extraction method of frankincense volatile oil. The method comprises steps as follows: frankincense powder is placed in an extraction kettle, the supercritical CO2 extraction method is used, the extraction pressure of the extraction kettle is 30-36 MPa, the extraction temperature is 40-45 DEG C, and the extraction time is 60-90 min; the flow velocity of CO2 is 200-300 kg / hr; the pressure of a separation kettle I is 8-12 MPa, the extraction temperature is 40-50 DEG C, the pressure of a separation kettle II is 4-6 MPa, and the extraction temperature is 35-40 DEG C. The frankincense volatile oil is extracted with the supercritical CO2 method, the extracted oil yield is high, the average oil yield is 21.0%, more components are extracted, CO2 volatilizes easily, no organic solvent residues exist, the extraction temperature is lower, volatile components cannot be damaged easily, and oxidation of unstable components is avoided. The supercritical CO2 frankincense extract has significant analgesic and anti-inflammatory effects on mice.
Description
technical field [0001] The invention belongs to the technical field of traditional Chinese medicines, and in particular relates to a method for extracting frankincense volatile oil. Background technique [0002] The demand for frankincense in my country's traditional Chinese medicine industry is increasing year by year. There are 57 prescriptions containing frankincense in the "Chinese Pharmacopoeia" (2010 edition). The effects of frankincense and its processed products are: promoting blood circulation and relieving pain, reducing swelling and promoting muscle growth. It is mainly used to treat common and frequently-occurring Chinese herbal medicines such as chest obstruction and heartache, epigastric pain, dysmenorrhea, rheumatic arthralgia, bruises, carbuncles, sores and sores. [0003] At present, the extraction method of frankincense volatile oil is single, and it is difficult to fully extract its active ingredients, and the anti-inflammatory effect of the obtained prod...
