Abstract
The present invention is the process of extracting woodfrog egg oil. Stoved woodfrog egg is first crushed in a crusher to powder of 10-30 meshes and then extracted inside one sealed supercritical CO2 extracting equipment to obtain oil with the extracting conditions including 20-35 MPa pressure and 30-45 deg.C, temperature. The woodfrog egg oil extracted under relatively lower temperature has unsaturated fatty acid no easy to be oxidized, no residual solvent and high quality and is suitable for use as pharmaceutical material.
Description
The present invention relates to a kind of extracting method of forest frog's egg fat, is a kind of CO of utilization specifically
2The method of supercritical extract is extracted the method for forest frog's egg fat.
The ovum oil of wood frog (having another name called clam scholar toad) contains multiple polyene unsaturated fatty acid, and forest frog's egg fat has effects such as significant inhibition platelet aggregation, reducing blood lipid.As medicinal, need forest frog's egg fat is extracted from the wood frog ovum for convenience.In the prior art, people such as Li Chengyi disclose a kind of method of extracting forest frog's egg fat from the wood frog ovum in Chinese periodical " CHINA JOURNAL OF CHINESE MATERIA MEDICA " 1991,16 (12) 744, and this method is to extract forest frog's egg fat with solvent extraction.Since be to extract with solvent extraction, the residual solvent that balance is arranged of meeting in the forest frog's egg fat after extraction, in addition, solvent extraction temperature height, do not isolate with air, unrighted acid in the forest frog's egg fat that extracts is easy to oxidized, influences the quality of forest frog's egg fat, so that be not suitable for pharmacy.
The objective of the invention is in order to overcome above-mentioned deficiency, the unrighted acid that proposes not have in residual solvent, the forest frog's egg fat in the forest frog's egg fat after a kind of extract is difficult for the oxidized CO that utilizes
2The method of supercritical extract forest frog's egg fat.
The present invention is achieved using the following method.
Utilize CO
2The method of supercritical extract forest frog's egg fat is: earlier the wood frog ovum of drying is ground into 10～30 purpose powder with pulverizer, then at CO
2Use CO in the supercritical extract equipment
2Grease in the method extraction wood frog ovum powder of supercritical extract, CO
2The condition of supercritical extract is: pressure 20～35MPa, 30～45 ℃ of temperature.The forest frog's egg fat that extracts is the oily liquids of Chinese red.
The present invention adopts airtight CO
2Supercritical extract equipment is under lower temperature, with the CO of supercriticality
2Extract forest frog's egg fat, the insatiable hunger in the forest frog's egg fat after the extraction is closed aliphatic acid and is difficult for oxidizedly, does not have residual solvent in the forest frog's egg fat, and quality is better, suitable raw material as pharmacy.
Below in conjunction with embodiment, the present invention is further illustrated.
Embodiment 1, gets 150 kilograms on the wood frog ovum of oven dry, is ground into 10～30 purpose fine powders with beater disintegrating machine, at 300 liters CO
