紫外光谱法评价植物提取物防晒效果的实验设计

Experimental Design for Evaluating Sunscreen Efficacy of PlantExtracts Using UV Spectrophotometry

紫外线是造成光老化的主要外在因素,对肌肤构成潜在威胁。天然植物提取物因具有紫外吸收的作用,毒副作用小或无毒作用,且还具有抗氧化、抗炎等功效,是比较理想的天然防晒剂的原料。通过紫外分光光度计检测植物提取物的防晒效果,其操作简单、便捷,学生更易理解与接受。通过实验过程,旨在提升学生的实验操作技能、数据处理与图表绘制能力,进而深化其对专业知识的理解与应用,为未来从事相关领域的科研工作奠定坚实基础。

Ultraviolet radiation,the primary external factor causing photoaging,poses a potential threat to skin health.Natural plant extracts,with their ultraviolet-absorbing properties,low toxicity or non-toxicity,as well as antioxidant and anti-inflammatory effects,serve as ideal raw materials for natural sunscreens.The detection of the sunscreen effect of plant extracts using a UV spectrophotometer is a simple and convenient method that is easy for students to understand and accept.This experimental process aims to enhance students'experimental skills,data processing,and charting abilities.Furthermore,it aims to deepen their understanding and application of professional knowledge,laying a solid foundation for future research work in related fields.
