Baical skullcap root extract self-micro-emulsion with biological bacteriostasis

The invention discloses a baical skullcap root extract self-micro-emulsion with the biological bacteriostasis. The baical skullcap root extract self-micro-emulsion is a self-micro-emulsion which uses2-6% of a baical skullcap root CO2 supercritical extract as an active substance, is formed by mixing the active substance with 10-40% of a non-ionic surfactant, 20-50% of a short-chain fatty alcohol,and 20-55% of modified vegetable oil, and easily forms a thermodynamically stable micro-emulsion system with water. After the self-micro-emulsion of the invention is diluted with water, the diluted self-micro-emulsion can be used as a livestock and poultry disinfection and sterilization bacteriostat and a livestock and poultry growth promoter to promote the growth of the livestock and poultry andimprove immunity. 本发明公开了一种具有生物抑菌性的黄芩提取物自微乳剂，是以2～6%黄芩CO超临界提取物为活性物质，与10～40%非离子表面活性剂、20～50%短链脂肪醇、20～55%改性植物油混合形成的易于与水形成热力学稳定微乳液体系的自微乳剂。将本发明自微乳剂用水稀释后，可以作为畜禽消杀抑菌剂和畜禽生长促进剂使用，用以促进畜禽的生长和提高免疫力。
