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.
