Wood frog extracted lyophilized powder and application of wood frog extracted lyophilized in preparing medicaments and cosmetics for treating acne

The invention provides wood frog extracted lyophilized powder and an application of the wood frog extracted lyophilized in preparing medicaments and cosmetics for treating acne, and belongs to the technical field of biological pharmacy. The wood frog extracted lyophilized powder is prepared by the following steps: removing impurities and dust from a wood frog, crushing, adding complex enzyme hydrolysate, centrifuging and taking the upper supernatant; grinding and cutting a remained mixture, spraying and drying to obtain powder; adding the superfine powder into acetic acid, performing ultrasonic treatment, filtering by means of a gauze, centrifuging, and concentrating the supernatant at reduced pressure to obtain a mixture of polysaccharide, antibacterial peptide and calcium ions; and mixing the substances to obtain a wood frog extracted mixed liquid, pre-freezing, sublimating, desorbing and post-treating to obtain the wood frog extracted lyophilized powder. The lyophilized powder is a pure biological preparation and does not have side effect, wherein the oligopeptide collagen can relatively well enter a normal cell under the action of the polysaccharide, is capable of supplying sufficient nutrition to the cell and repairing injured cells; and the antibacterial peptide can be combined with the calcium ion to enhance destruction of the antibacterial peptide on a bacterial cell wall, and enters the bacterial cell to achieve the effect of inhibiting bacteria.
