Problems solved by technology

[0003] At present, the research on asparagus mainly focuses on its rhizomes, but there is little research on the seeds. In fact, the seeds of asparagus are rich in fatty oil, which is an important component of traditional Chinese medicine. Currently, the seeds of asparagus are obtained The oil is all pressed by the traditional method, not only the workload is heavy, but also the recovery rate is very low, resulting in a waste of effective resources

Abstract

Relating to a seed oil extraction method of Asparagus cochinchinensis (Lour.) Merr., the invention adopts a supercritical CO2 method for extracting the seed oil of Asparagus cochinchinensis (Lour.) Merr. The method comprises: putting crushed Asparagus cochinchinensis (Lour.) Merr. Seeds into an extraction tank; employing supercritical CO2 as an extracting agent, adjusting the pressure to 30MPa, the temperature to 45DEG C, and the CO2 flow at 20kg / h, and controlling the extraction time at 90min; conducting first-stage separation at a pressure of 8MPa and a temperature of 40DEG C, after extraction, getting back separated oil, and continuing separating the part that is not separated; carrying out second-stage separation at a pressure of 6MPa and a temperature of 40DEG C, after extraction, getting back the separated oil, and leaving the part that is not separated flows back into the extraction tank, and continuing conducting separation. The beneficial effects of the method provided in the invention are: high purity of Asparagus cochinchinensis (Lour.) Merr. seed oil, short extraction time, high efficiency, no residual solvent, simple process, convenient operation, high product quality, as well as high extraction rate.

Description

technical field [0001] The present invention relates to a kind of extraction method of plant seed oil, especially a kind of supercritical CO 2 Method for extracting asparagus seed oil. Background technique [0002] Asparagus cochinchinensis (Lour.) Merr., also known as asparagus, is an evergreen vine of Liliaceae, and its roots are used as medicine. It is mainly produced in Guizhou, Guangxi, Yunnan, Gansu, Anhui, Henan, Hunan, Hubei, Sichuan and Jiangxi. Asparagus was first recorded in "Shen Nong's Materia Medica", and it has been recorded in successive dynasties of herbal medicines. It is sweet, bitter, cold in nature, belongs to the lung and kidney meridian, can nourish yin and moisten dryness, clear lung and generate body fluid; it is mainly used for dry cough due to dryness of the lung, cough due to consumptive fatigue, thirsty body wound, insomnia due to complex heart, internal heat and thirst, constipation due to dryness of the intestine, etc. disease. It can also ...
