Embodiment Construction

[0009] The placenta carbon dioxide supercritical extraction method of the present invention will be further described below in conjunction with specific examples.

[0010] Freeze-dry the placenta obtained under aseptic conditions, vacuum freeze-dry at -5°C to -6°C for 5-6 hours, and grind it into a 100-mesh fine powder; add the placenta fine powder to the extraction kettle In the process, carbon dioxide with a pressure of 30-40Mpa is introduced, and the extraction is carried out at 30-40°C for 8-12 hours; after one-stage decompression separation, the operating pressure is 8-12Mpa, and the operating temperature is 30-35°C; Separation under reduced pressure, the condition is that the operating pressure is below 6Mpa, and the operating temperature is 15-25°C. The placenta is obtained by collecting the products separated under reduced pressure.

Abstract

This invention discloses a placenta carbon dioxide super threshold extraction method, which comprises the following steps: freezing and drying the placenta under temperature of -5íµ í½-6íµ for five to six hours and grinding it into powder; putting the powder into the extraction kettle and drawing carbon dioxide of 30í½40Mpa under temperature of 30í½40íµ for extraction; processing two degree decompression isolation to get the placenta under 8í½12Mpa and temperature of 30í½35íµ of first decompression isolation and under 6Mpa and temperature of 15í½25íµ of second degree decompression isolation.

Description

technical field [0001] The invention relates to a method for extracting placenta from human placenta, which is a method for extracting placenta by using carbon dioxide supercritical extraction technology. Background technique [0002] The placenta traditional Chinese medicine is called Ziheche, which has the functions of regulating human body functions, enhancing resistance, and tonifying vitality, essence and blood. Placenta is a medicinal ingredient extracted from the placenta, which contains a variety of hormones and biological enzymes. At present, the extraction of placenta mostly adopts the method of decoction and concentration. This method can not only extract a small amount of placenta, but also consumes a lot of energy and costs high, and some active gene regulatory factors and some metabolic regulatory enzymes in the placenta will be affected due to Inactivated by high temperature, the utilization value of placenta is reduced.
