摘　　要：以一年生和二年生黄芩为试材,研究了不同部位、不同生长时期总黄酮含量的累积规律,以期为黄芩的种植和确定最佳采收时期提供参考。结果表明:黄芩总黄酮含量"根>叶>茎";在一年生和二年生黄芩中的累积规律不同,其中一年生黄芩根总黄酮含量在9月份最高、达到46.97mg/g,二年生黄芩根总黄酮含量在6月份最高、达到54.50mg/g,显著高于其它时期;因此,确定一年生黄芩最佳采收时期为9月份,二年生黄芩最佳采收时期为6月份。Taking the annual and biennial Scutellaria baicalensis of Changbai Mountain as test materials,the total flavonoids content in different organs and different growth periods were studied,to provide reference for cultivation and determine the optimum harvesting time.The results showed that the total flavonoids content was‘rootleafstem＇,but the accumulation rule of total flavonoids content between annual and biennial S.baicalensis was different,the highest total flavonoids content of root of annual S.baicalensis was obtained in September（46.97mg/g）,whereas the highest total flavonoids content of root of the biennial S.baicalensis was obtained in June（54.50 mg/g）,which was significantly higher than other periods.Therefore,the optimum harvesting time of annual S.baicalensis was in September,and the optimum harvesting time of the biennial S.baicalensis was in June.
