中文摘要: 以玫瑰花瓣和花托为原料，通过乙醇浓度、提取时间、提取温度、料液比单因素试验和 L9（34）正交试验，用极 差分析优先法获得最佳黄酮含量的提取条件；通过粉碎-提取-过滤-浓缩-喷雾干燥，分别获得玫瑰花瓣、花托醇提 法和水提法的速溶产品。结果表明玫瑰黄酮醇提最佳条件为料液比为 1 ∶ 10（g/mL）、提取温度 60 ℃、提取时间 60 min、乙醇浓度 60 %；乙醇提取法的速溶产品产率分别为：花托的产率为 1.95 %，花瓣的产率为 4.37 %，蒸馏水提 取法的速溶产品产率分别为：花托的产率为 21.28 %；花瓣的产率为 10.32 %。
Abstract:Used rose petals and receptacle as raw materials， the single factor experiment and L9（34） orthogonal test were made by ethanol concentration， extraction time， extraction temperature and material liquid ratio. The best effect analysis the extraction of flavonoids content conditions was obtained by preferred method， and the shattered-extraction-filter-enrichment-spray drying was used to get rose petals， receptacle alcohol formulation and water soluble products， respectively. Results showed that the best extraction of rose flavonol conditions was that the material fluid volume ratio was 1 ∶ 10（g/mL）， extracting temperature was 60 ℃， and the extraction time was 60 minutes， ethanol concentration was 60 %. Ethanol extraction of instant product production rate was 1.95 % receptacle production rate， and the yield of the petals was 4.37 %. Distilled water extraction could get 21.28 % receptacle， and petals got yield of 10.32 %， respectively.
