摘要
目的从金钱草中提取总黄酮和多糖,并测定其含量。方法运用微波技术提取金钱草总黄酮和多糖,用比色法测定总黄酮和多糖含量。结果测得金钱草中总黄酮含量为1.36%,平均回收率为100.4%,RSD为1.56%(n=5);多糖含量为8.46%,平均回收率为101.6%,RSD为1.23%(n=5)。结论运用微波技术从金钱草中联合提取总黄酮和多糖,反应速度加快,提高了提取效率。
OBJECTIVE To extract and determine total flavonoids and polysaccharides in Lysimachia Christinae Hance.METHODS Total flavonoids and polysaccharides in Lysimachia Christinae Hance were extracted by microwave technique and determined by colorimetry. RESULTS Total flavonoids in Lysimachia Christinae Hance was 1.36%,and recovery rate was 100.4%,RSD was 1.56%(n=5);Polysaccharides in Lysimachia Christinae Hance was 8.46%,and recovery rate was 101.6%,RSD was 1.23%(n=5).CONCLUSION Microwave Technique is applied to extracting total flavonoids and polysaccharides in Lysimachia Christinae Hance for the first time.The reaction speed is faster and the result is satisfactory.
