Sheep placenta extracting solution with anti-aging function as well as preparation method and application thereof

Abstract

The invention discloses a sheep placenta extracting solution with an anti-aging function as well as a preparation method and application thereof. The preparation method comprises the following steps of S1, taking sheep placenta in an embryo period, separating cotyledons, discarding fetal membranes, cleaning the cotyledons with normal saline, and dicing the cotyledons; S2, soaking the cotyledon blocks in a peroxyacetic acid solution, and then cleaning the cotyledon blocks with purified water; S3, adding a taurine solution into the cotyledon blocks, and carrying out crushing and homogenizing toobtain slurry; S4, oscillating and centrifuging the slurry, and separately collecting supernatant and precipitate; S5, adding taurine into the precipitate, carrying out negative pressure cavitation extraction, performing centrifuging, and collecting the supernatant; S6, mixing the supernatant, adjusting the pH value, oscillating, centrifuging, and collecting the supernatant; S7, adjusting the pH value of the supernatant, carrying out complementing and inactivating, then adjusting the pH value, performing centrifuging, and collecting supernatant; and S8, carrying out ultrafiltration concentration on the supernatant, and performing filtering and degerming to obtain the product. The extract disclosed by the invention has the effects of moisturizing, resisting wrinkles, delaying senescence andenhancing the skin immune function when being applied to cosmetics, and has a wide market prospect.

Description

technical field [0001] The invention belongs to the technical field of extract preparation, in particular to a sheep placenta extract with anti-aging function and its preparation method and application. Background technique [0002] Aging is an inevitable stage in the life activity process of any organism. As people grow older, people are affected by various factors inside and outside the body, and the body will inevitably experience the aging process of the body's morphological structure and physiological functions. As the largest and most easily exposed organ of the body, the skin is responsible for many aspects of body protection, sensation, temperature regulation, secretion, excretion and immunity, and is also one of the most obvious organs in body aging. In recent years, the conclusion that ultraviolet rays cause skin photoaging has been widely accepted. Ultraviolet rays can be divided into short, medium and long-wave ultraviolet rays according to their wavelengths. ...

AI Technical Summary

Problems solved by technology

[0004] In the existing methods for extracting sheep placenta, most of them adopt enzymatic hydrolysis and high-temperature sterilization in the process. Enzymatic hydrolysis and high temperature will destroy the natural active substances in the placenta, making it difficult to guarantee the types and contents of natural active substances. It is beneficial to ensure the quality of sheep placenta extract, and the extraction efficiency is not high

Moreover, the anti-aging effect of sheep embryo / sheep placenta extract in the prior art is too general, and the bioactive components with anti-aging effect have not been fully extracted.
