[摘要]目的:制备驻颜乳剂凝胶并对其质量及药效进行考察。方法:以综合评分为响应值,通过Box-Behnken响应面法筛选驻颜乳剂凝胶的制备方法,并对影响驻颜凝胶质量的项目进行了相关测试,通过测定驻颜乳剂凝胶羟自由基、超氧离子自由基、DPPH自由基三者的IC50值考察其体外抗氧化作用,通过测定小鼠皮肤匀浆液中羟脯氨酸(HYP)、丙二醛(MDA)、超氧化物歧化酶(SOD)与含水率的变化考察驻颜凝胶延缓皮肤衰老的作用。结果:乳剂凝胶的最佳制备工艺为卡波姆用量1.00%、甘油用量15.00%、pH6,且各项试验项目均符合要求;不同浓度的驻颜乳剂凝胶均具有一定程度体外抗氧化能力,与对照组相比,能显著升高小鼠皮肤中SOD活力(P<0.05,P<0.01),降低MDA水平(P<0.05,P<0.01),减少HYP含量(P<0.05,P<0.01)。结论:本驻颜乳剂凝胶符合凝胶局部外用制剂要求,质量稳定可靠,对小鼠皮肤衰老具有延缓的作用,为凝胶剂进一步的研究与开发提供了新思路。

Abstract: Objective Prepare the Zhuyan emulsion gel and investiga its quality and efficacy. Methods Taking the comprehensive score as the response value, the preparation method of the resident facial emulsion gel was screened by the Box-Behnken response surface method, and related tests were conducted on the items affecting the quality of the resident facial gel. the anti-oxidation effect of in-vivo emulsion was determined by measuring the IC50 value of hydroxy hydroxyl radical, superoxide ion radical and DPPH radical, and by measuring superoxide dismutase (SOD), malondialdehyde (MDA), The changes of hydroxyproline (HYP) and water content were used to investigate the anti-aging effect of Zhuzhan gel. Results The best preparation process of emulsion gel is carbomer dosage 1.00%, glycerol dosage 15.00%, Ph 6, and all test items meet the requirements,and pH, viscosity, moisturizing rate, microbial limit, content and other test items all meet the requirements, and different concentrations of resident facial emulsion gels have a certain degree of antioxidant capacity in vitro,can significantly increase the SOD activity in mouse skin (P<0.05, P<0.01), reduce MDA level (P<0.05,P<0.01),reduce HYP content (P<0.05,P<0.01). Conclusion The preparation technology of this gel is simple, conforming to the main index requirements of gel topical preparation, stable and reliable quality, and has a retarded effect on skin aging in mice. It provides a new idea for further research and development of gel.

機体衰老是所有生物体不可逆的自然生命现象,是指生物发育成熟后,随着机体年龄不断增加,机体的各个器官组织以及器官结构发生长期退行性结构变化而逐渐产生的一种不可逆过程,其中尤以人体外在皮肤结构改变最为明显。皮肤衰老的主要表现是皮肤弹性的减弱、各种皱纹色斑的不断形成、水分的随之减少[1-3]。现有医学理论研究认为,大部分肌肤产生色斑老化的现象与机体自由基的产生被破坏有关。当机体皮肤内的自由基被严重破坏,皮肤深层细胞的自体免疫能力也将随之迅速下降,从而对皮肤机体功能造成严重伤害,引起衰老[4-5]。……
