The invention belongs to the technical field of biological medicines, and particularly discloses a Pi scorpion polypeptide and application thereof. Through molecular biology, site-specific mutagenesis, chemical synthesis and other methods, the obtained Pi scorpion polypeptide can effectively inhibit the growth of escherichia coli, pseudomonas aeruginosa, staphylococcus aureus, propionibacterium acnes and related drug-resistant bacteria at low concentration. The pemai Pi scorpion polypeptide has a very good effect in treating or preventing folliculitis, furuncle, impetigo, acne and whelk caused by escherichia coli, pseudomonas aeruginosa, acinetobacter baumannii, propionibacterium acnes, staphylococcus aureus, related drug-resistant bacteria and the like. The pemai Pi scorpion polypeptide disclosed by the invention has good activity in resisting escherichia coli, pseudomonas aeruginosa, acinetobacter baumannii, propionibacterium acnes, staphylococcus aureus and related drug-resistant bacteria, and can be further developed and utilized as an antibacterial drug for treating folliculitis, furuncle, impetigo, acne, whelk and the like.

The invention discloses an application of betulinic acid 28-O-beta-D-glucoside (BA-6 for short) in preparation of a medicine for preventing and treating skin inflammation. The problems that an existing medicine for treating dermatitis is limited in curative effect, slow in effect taking, multiple in side effect, high in long-term use risk, large in individual difference, high in treatment cost, likely to cause immunoreaction and the like are solved. The invention discloses application of BA-6 in prevention and treatment of atopic dermatitis, contact dermatitis, eczema, rash, psoriasis, lupus erythematosus, papule squamous skin disease, pityriasis rosea, seborrheic dermatitis, pemphigus, celestial abscess, acne, tinea corporis, impetigo, SAPHO syndrome, hidradenitis suppurativa, dermatitis caused by drugs, lichen planus, pityriasis rubra pilaris, vitiligo, prurigo nodularis, dermatitis caused by drugs, and the like for the first time. The traditional Chinese medicine composition can be used for treating skin diseases, systemic sclerosis, hidradenitis suppurativa, granulomatous skin diseases, vitiligo, dermatomyositis, chronic skin itch and alopecia areata, and has the technical progress of obviously improving skin erythema, papule, edema, scale, moss and ulceration symptoms.
