玫瑰花黄酮提取及速溶产品的研究

Study on the Extract of Flavonoids from Rose and Instant Product Exploration

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/m L)、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%。

Used rose petals and receptacle as raw materials, the single factor experiment and L9（3^4） orthogonal test were made by ethanol concentration, extraction time, extraction temperature and material liquid ratio. The best effect analysis the extraction of fiavonoids 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.
