Abstract

The invention belongs to the technical field of scald ointment, and discloses almond oil scald ointment as well as a preparation method and application thereof. The method comprises the following steps: 1) reacting almonds with protease, and centrifuging to obtain supernatant which is sweet almond oil; filtering and drying the subnatant to obtain the almond polypeptide; (2) reacting the apricot pulp with polysaccharide hydrolase to obtain apricot oligosaccharide; (3) reacting the almond oil with lipase, adding a water-insoluble organic solvent and apricot oligosaccharide, and continuously reacting to obtain an almond oil and apricot oligosaccharide conjugate; (4) respectively preparing the almond polypeptide and the almond oil and oligosaccharide conjugate into dispersion liquid; under the stirring condition, the almond polypeptide dispersion liquid and the almond oil and oligosaccharide conjugate dispersion liquid are mixed and filtered through a filter membrane, and the almond oil scald ointment is obtained. The scald ointment disclosed by the invention can prevent infection and regulate metabolism balance of fat, sugar and protein of subcutaneous tissues, so that formation of scars is reduced while wound healing is promoted. The scald ointment is used for preparing medicines for preventing and treating scalds and repairing scars.

Description

technical field [0001] The invention belongs to the field of medicine, and in particular relates to an almond oil scald ointment and a preparation method and application thereof. Background technique [0002] Burns are tissue injuries caused by flames, high-temperature steam or liquids, mainly the skin or mucous membranes, and can seriously injure the subcutaneous tissue. Can cause local pain, skin redness, blisters, damage and so on. Wound treatment and timely drug application can effectively reduce the continuous damage and accelerate recovery, but improper drug use not only delays recovery, but also produces scars. Scars are due to changes in the local microenvironment during the wound healing process, which disrupts the balance of collagen synthesis and decomposition functions, resulting in abnormal accumulation and arrangement of scar collagen fibers. Commonly used drugs include anti-infection drugs and saprophytic drugs, such as antibiotics, some activating blood cir...
