OBJECTIVE
To study the optimal extraction process of polysaccharide from Baphicacanthus cuaia (Nees) Bremek.
METHODS
The optimal extraction process was selected with uniform design and statistical analysis system (SAS). The content of polysaccharide in the extract was determined to investigate the influence of temperature of extraction, the time of extraction and the solid-liquid ratio on it.
RESULTS
The optimal extraction process was extraction temperature 90 degrees C with 2 hours and with 1:50 (g/ml) of Baphicacanthus cuaia (Nees) Bremek weight to distilled water. The optimum extraction rates of Polysaccharide from Baphicacanthus cuaia (Nees) Bremek and Isatis indigotica Fort were 3.26% and 12.76%.
目的
研究马蓝多糖的最佳提取工艺。
方法
采用均匀设计和统计分析系统（SAS）筛选最佳提取工艺。测定提取物中多糖的含量，考察提取温度、提取时间和固液比对其的影响。
结果
最佳提取工艺为提取温度90℃、提取时间2小时、马蓝与蒸馏水的固液比为1:50（g/ml）。马蓝和菘蓝多糖的最佳提取率分别为3.26%和12.76%。
