Study on the Characteristics of Water Absorbance, Infrared Spectroscopic Analysis and Extraction Technology of Mucilage from Salvia przewalskii Seeds

  • 摘要: 本研究在对甘西鼠尾草种子粘液的吸水特性和红外光谱进行分析的基础上,利用响应面分析方法优化甘西鼠尾草种子粘液的提取工艺,并利用中心组合设计探讨提取时间、液料比、提取温度3个自变量对甘西鼠尾草种子粘液提取率的影响。结果表明,甘西鼠尾草种子粘液是一类多糖物质,吸水性强,脱水缓慢;甘西鼠尾草种子粘液优化的提取工艺条件为:提取时间3.2 h、液料比54:1(mL:g)、提取温度68℃,此时种子粘液提取率为4.93%,这为甘西鼠尾草种子粘液资源的开发应用提供了理论依据。

     

    Abstract: Taking Salvia przewalskii seeds as the raw materials, the conditions for extraction, water absorbance characteristics, and infrared spectroscopy of mucilage were studied. Based on single factor experiments, mucilage conditions from Salvia przewalskii seeds were optimized using response surface methodology. A central composite design was used to investigate the effects of three independent variables, namely, extraction time, liquid-to-solid ratio, and extraction temperature on the yield of mucilage. Results showed that mucilage absorbed water well, and dehydrated slowly. Infrared spectroscopy demonstrated that the seed mucilage was a compound of polysaccharides. Optimum extraction conditions were an extraction time of 3.2 h, liquid-to-solid ratio of 54:1 (mL:g), and extraction temperature of 68℃. The maximum extraction yield of mucilage was 4.93%.
