摘要 目的单因素试验了不同体积分数的乙醇、料液比、提取温度及提取时间等因素对南方碱蓬叶总黄酮(LFSA)提取率的影响。方法以正交设计实验所得的最佳提取条件提取LFSA,用聚酰胺吸附-硝酸铝显色法测定其含量。结果LFSA的优化提取条件为30倍原料重的75%乙醇溶液在80℃条件下提取30min,含量为6.35%。结论LFSA的提取含量约为6.35%。 OBJECTIVE To investigate the extraction and content of total flavonoids in Suaeda australis leaves (LFSA). METHODS The effects on the extraction rate of different concentration ethanol, ratio of material to liquid, extraction temperature and time were studied, respectively. LFSA extracted by the optimum extraction conditions from the orthogonal experiment, purified by polycaprolactan and produced color with Al(NO3)3, and the content of total flavonoids was measured. RESULTS The optimum conditions of extraction were as follows: ratio of material to 75% ethanol was 1:30, extraction temperature was 80℃ ,extraction time was 30minuter. CONCLUSION The content of LFSA was about 6.35%.
