Embodiment approach

[0020] Dissolve 1g of cobra snake venom in 100ml of deionized water, centrifuge at 4°C and 5000rpm for 15 minutes, and take the supernatant for gel filtration chromatography; gel filtration uses Sephadex-G-75 gel column with a column height of 100cm and an inner diameter of 1.6cm , the eluent is the ammonium acetate solution of 0.05mol / L, the elution rate is 16ml / h, and 1 tube is collected in 10 minutes; the toxin components that cause hemorrhage are removed after separation, and the remaining components are freeze-dried to obtain the refined cobra venom dry powder.

[0021] Baicalein is extracted from Scutellaria baicalensis Chinese medicinal materials, the specific implementation method:

[0022] Add 100g of medicinal material Scutellaria baicalensis, add 500ml of distilled water after crushing, pass through a 20-mesh sieve after fully stirring, add 2000U cellulase at 40°C, pH4.5 for enzymolysis for 24 hours, then suction filter, add 60% ethanol to the solid obtained by suct...

Abstract

The invention discloses an anti-acne snake venom compound external application preparation and a preparation method thereof. The anti-acne snake venom compound external application preparation contains 1 to 8 percent of active pharmaceutical ingredients, wherein the active pharmaceutical ingredients are obtained by mixing 50 to 70 percent of dry elapidae snake venom powder with 30 to 50 percent of baicalein product, the percentage is by mass. Per 100g of fined dry elapidae snake venom powder is prepared from the following components: 6 to 12g of neurotoxin, 10 to 45g of cardiotoxin, 1.5 to 3g of cobra venom factor and 0.2 to 0.5g of cobra venom nerve growth factor; the content of baicalein in per 100g of the baicalein product is greater than 98g. The neurotoxi, cytotoxin and nerve growth factor of cobra venom have the effects of inhibiting bacteria, resisting inflammation, resisting allergy and relieving skin lesion; by coordinating the effects of the cobra venom with the effects of resisting oxidation, resisting inflammation and reducing grease secretion of the baicalein, the skin irritation and drug resistance of an anti-acne medicament can be reduced, and a more ideal biological agent is provided for clinical acne treatment.
