The invention relates to a preparation method of the extract of longan, which adopts the simultaneous enzymatic hydrolysis extraction method of pectinase and cellulase double enzyme. The concrete preparation steps are as follows: the fresh longan is dried by hot wind at 80 C, peeled and deformed, obtained the dried longan flesh, sealed at 4 degrees centigrade at low temperature, and was called the dried longan fruit, and added deionized water to soak. 12h, the ratio of material to water is 1:3, mashed with high speed tissue mashing machine, and the mixture of mashed material was added to the deionized water at this time, the ratio of the material to water was at 1:12, and the two enzymes of pectinase and cellulase were enzymolysis at the same time. According to the mass percentage, the amount of pectinase was 0.6%, the dosage of cellulase was 0.05%, the pH value was 3.1, the enzymolysis temperature was 52, and enzymolysis. At the time of 160min, after the enzymatic hydrolysis, the enzyme was destroyed by 30min at 90 C. The filtrate was collected by 200 mesh filter. The filtrate was concentrated to the semi liquid pulp. Then the pulp was dissolved in the deionized water at the 1:10 volume ratio, and the extract was obtained by mixing and shaking.

技术介绍
青春痘又名痤疮,痤疮的发生主要与皮脂分泌过多、毛囊皮脂腺导管堵塞、细菌感染和炎症反应等因素密切相关。进入青春期后人体内雄激素特别是翠酮的水平迅速升高,促进皮脂腺发育并产生大量皮脂。同时毛囊皮脂腺导管的角化异常造成导管堵塞,皮脂排出障碍,形成角质栓即微粉刺。毛囊中多种微生物尤其是痤疮丙酸杆菌大量繁殖,痤疮丙酸杆菌产生的脂酶分解皮脂生成游离脂肪酸,同时趋化炎症细胞和介质,最终诱导并加重炎症反应。随着人们消费意识的提升,消费者在选用清洁品和护肤品的时候越来越注重产品的安全性,产品的安全性远远要比治疗性和美容性本身重要的多。天然植物和动物的提取物本身致敏率很低,安全性很高,利用该种活性成分提取物制备生产的产品也越来越受到消费者的重视和喜爱。纳米石墨烯可以杀死绿脓杆菌、大肠杆菌等10 ...
