从玫瑰到精油：一场化学探索之旅
摘要：实验借助 DeepSeek、豆包等人工智能工具策划完整流程，以新鲜平阴玫瑰花瓣为核心材料，搭配蒸馏水、食盐、乙酸乙酯等试剂及过滤、蒸馏、萃取等专业仪器，历经采摘、挑选、腌制、破壁、过滤、萃取、分液、蒸馏等 12 个实操步骤，成功提取出淡黄色澄清玫瑰精油，同步制得可食用玫瑰盐及香薰香包。本实验深度实践了化学分离与提纯核心技术，验证了玫瑰品种、采收时间、操作规范对精油提取效果的关键影响，为青少年科创实践提供了可复制的完整案例，同时提出后续可探究不同玫瑰品种、萃取剂类型及提取条件的优化方向。

From Roses to Essential Oil: A Journey of Chemical Exploration
This experiment utilized artificial intelligence tools such as DeepSeek and Doubao to plan the complete procedure. Using fresh Pingyin rose petals as the core material, along with reagents including distilled water, sodium chloride, and ethyl acetate, and professional instruments for filtration, distillation, and extraction, the process involved 12 practical steps: picking, selection, curing, cell disruption, filtration, extraction, liquid separation, and distillation. Successfully, a pale yellow clear rose essential oil was extracted, while edible rose salt and aromatic sachets were simultaneously produced. This experiment provided an in-depth practice of key chemical separation and purification techniques, verifying the critical effects of rose variety, harvesting time, and operational standards on the essential oil extraction outcome. It offers a replicable case study for youth science and innovation practices and proposes future research directions, such as optimizing extraction conditions by exploring different rose varieties and types of extraction solvents.
