摘要
目的:优化白及粗多糖的提取工艺。方法:采用正交试验法,以白及粗多糖的提取率为指标,考察白及的粉碎粒度、提取时间和提取温度对提取工艺的影响。结果:最佳提取工艺为60目白及细粉分别以8、6和4倍量纯化水为溶剂提取3次,提取时间分别为3:2:2h,提取温度为90℃。结论:该提取工艺稳定可行,质量可控。
OBJECTIVE：To optimize the extraction technology for the polysaccharides from Rhizoma Bletiliae.METHODS： The impacts of grinding particle size, the extraction time and temperature on the extraction technology was studied by orthogonal experiment with the extracting rate of striata polysaccharides as markers. RESULTS： The optimum extraction condition was to add 8, 6 and 4 times purified water respectively to Rhizoma Bletiliae powder and extract at 90 ℃ for 3 ： 2 ： 2 hours respectively. CONCLUSION： The extraction technique is stable and feasible and the quality of the polysaccharides is controllable.
