不同产地、不同部位黄芩的黄芩甙含量测定

Comparative Study on the Content of Baicalin in Different Parts of Scutellaria from Different Sources

采用HPLC技术对不同产地、不同部位的黄芩的黄芩甙含量进行分析测定。结果表明 :枯芩和条芩中黄芩甙的含量相差较大 ,后者约为前者的 4倍 ;条芩中皮部和木质部中的黄芩甙含量也有明显区别 ,后者约为前者的2倍。提示在中药生产和临床应用时应当严格区别黄芩的质地。

HPLC technology was employed to detect the content of baicalin in different parts of Scutellaria from different sources.Results showed that wizened Scutellaria and dried Scutellaria had different contents of baicalin,the latter was about as four times as the former;the contents in the bark and the xylem were various,and the latter was as twice as the former,which indicated that the part and source of Scutellaria should be differentially used in the production and clinical application of Scutellaria.
