摘要:

目的:为提高玫瑰精油水溶性与稳定性,以β- 环糊精为包合材料,制备并表征玫瑰精油的包合物。方法:采用饱和水溶液法制备玫瑰精油包合物,薄层色谱(TLC)、气相色谱- 质谱(GC-MS)分析包合前后精油的化学成分,并利用红外(IR)、差示扫描量热法(DSC)对包合物与包合作用进行表征与分析。结果:以包合率为指标确定包合最佳条件为:m 玫瑰精油:mβ- 环糊精=1:10,反应温度60℃,反应时间2h,在此条件下,玫瑰精油包合率达到80% 以上。结论:玫瑰精油包合物能够保留玫瑰精油的主要特征成分,提高精油的溶解度和稳定性,为开发口服玫瑰精油功能食品提供了固体粉末中间体。

Abstract:

In order to improve the solubility in water and stability of essential oil from Rosa damascena Miller, the essential oil was included with β-cyclodextrin(β-CD) by saturated water solution-stirring method. The inclusion conditions were optimized through orthogonal test, and the inclusion compound was characterized by thin-layer chromatography (TLC), gas chromatography-mass spectrometry (GC-MS), Fourier transform infrared (FTIR) spectrometry and differential scanning calorimetry (DSC). The results showed that the optimal inclusion conditions of essential oil from Rosa damascena Miller were as following: mass ratio of essential oil to β-CD 1:10, inclusion temperature 60 ℃, and inclusion time 2 h. The inclusion ratio of essential oil was up to 80% under above conditions. The inclusion compound retained the main characteristic components of the essential oil and obviously improved its solubility in water and stability. This β-CD inclusion compound of essential oil from Rosa damascena Miller can be used as a solid immediate for the development of functional foods.
