摘　　要：以云南省、广东省、广西壮族自治区不同地方葛根(Pueraria edulis)为材料,通过乙醇冷凝回流和超声波辅助提取法提取葛根药材中总黄酮,探究不同提取方式对不同地区葛根药材总黄酮含量的影响。结果表明,云南省葛根最佳提取时间均为20 min,广东省、广西壮族自治区葛根最佳提取时间均是30 min;冷凝回流提取法中葛根黄酮的得率相对较好;冷凝回流提取法中云南省产葛根总黄酮含量最高,平均含量为0.2557%,广东省葛根总黄酮平均含量最低为0.2108%。Taking Pueraria edulis from different places in Yunnan Province,Guangdong Province and Guangxi Zhuang autonomous region as materials,the medicinal materials of Pueraria edulis were extracted by ethanol condensation reflux extraction and ultrasonic-assisted extraction,and the effects of different extraction methods the contents of total flavonoids in Pueraria edulis from different areas were compared.The results showed that the best extraction time of Pueraria edulis in Yunnan Province was 20 min,and that in Guangdong and Guangxi Zhuang Autonomous Region was 30 min.The yield of total flavonoids from Pueraria edulis extracted by the condensation reflux extraction method was relatively better.The content of total flavonoids of Pueraria edulis in Yunnan was the highest with an average content of 0.2557%,while the average content of total flavonoids in Pueraria edulis in Guangdong was the lowest with an average content of 0.2108%.
