玫瑰芳香物质储藏部位与动态释放过程研究

目的]了解玫瑰芳香物质的动态变化与释放规律。方法]根据玫瑰花苞的大小和花朵开度将其划分为5个时期,利用比色法对玫瑰的主要芳香成分萜类物质进行连续定量分析,观察玫瑰的释香结构在开放过程中的变化。结果]玫瑰花瓣中油细胞是芳香物质的主要储藏场所;玫瑰提取物香气成分与玫瑰花瓣的芳香物质均随花朵的开放下降趋势放缓,玫瑰提取物初开放期、开放期和衰败期芳香物质含量明显高于玫瑰花瓣。结论]通过比色法对玫瑰开放期香气成分含量的动态变化进行定量分析是可行的,研究可为以玫瑰为依托开发精油、花水、花茶产业链等提供理论依据和借鉴。

Study on Aromatic Subsances Storage Position and Dynamic Release Process of Rose

Objective] The aim was to understand the dynamic change and release law of aromatic substances in rose.Method] There were 5 periods according to bud size of rose and opening degree.Continuous quantitative analysis was conducted on main aromatic components terpenoid substances of rose by colorimetric method. Result] The results showed that rose oil cell is the main storage site of aromatic substances;the aro-ma components of rose extract and the aroma compounds of rose petals are decreased with the opening of flowers;aromatic substance content in early opening period,opening period and decay period is obviously higher than that of rose petal.Conclusion] It is feasible to make a quantitative analysis on the dynamic change of aroma components in the open period of rose by the method of colorimetry.The study can provide a theoretical basis and reference for development of rose essential oil,rose water,rose tea industry chain.
