Human placenta lyophilized powder preparation and preparation method thereof

Abstract

The invention discloses a preparation method of a human placenta lyophilized powder preparation. The preparation method comprises: taking human placenta, washing to remove fascia and vessels, soaking in NaCl solution having a mass concentration of 10% for 5 h, chopping the human placenta, and performing low-temperature tissue homogenizing to obtain human placenta homogenate; mixing the homogenate with purified water, acquiring active factors in tissues and cells via a hypotonic method, and stirring for extracting to obtain tissue liquid; adding 0.8-2% of yeast powder for fermenting, and removing smell of the finished product; filtering with a 30-70 Mu m filter membrane to obtain human placenta liquid extract; lyophilizing to obtain human placenta lyophilized powder; packaging with capsule shells (HPMCAS or CAP) to obtain the human placenta lyophilized powder preparation. According to the preparation method, hypotonic homogenizing treatment is performed first, and yeast fermenting and smell removing are performed then before lyophilizing to obtain human placenta active material lyophilized powder that is made into capsules; the preparation method has the advantages that, for instance, nutrients are extracted fully and completely under high efficiency, the preparation is smellless, and the biological active ingredients are easy to absorb; a practicable technique for using human placenta resources to produce high-added-value nutrient health products is provided, and has a promising industrialization prospect.

Description

technical field [0001] The invention relates to a human placenta freeze-dried powder preparation and a preparation method thereof. Background technique [0002] Placenta, also known as purple river car, afterbirth, afterbirth and so on. Traditional Chinese medicine has always regarded placenta as an important medicine. Chinese medicine believes that Zihe Che has a sweet and salty taste, warm air, and is non-toxic. It is a medicine for invigorating the deficiency of both yin and yang, and has the effect of reversing the root and returning the essence. It is used to treat all deficiency and damage, loss of vigor and thinness, labor heat and bone steaming, nocturnal emission and night sweats, women's blood deficiency, impotence, infertility and other diseases. [0003] Now medical tests have found that the placenta is rich in various antibodies, interferon, β-inhibitory factors, fibrin stabilization factors similar to blood coagulation factor VIII, urokinase inhibitors, plas...

Problems solved by technology

Although the freeze-drying method disclosed in the Chinese patent application with publication number 104894201A improves the active ingredients through enzymatic hydrolysis, the termination process still adopts a high temperature of 95°C, which also causes a large number of biologically active substances to lose their efficacy while terminating the action of the enzyme.

In addition, in the prior art, most of the placenta is directly frozen into freeze-dried powder by freeze-drying method. When eating, the active substances pass through the stomach and most of them are digested and absorbed, which also makes it difficult to exert the efficacy of active molecules.
