青海省不同纬度小檗属3种植物不同部位小檗碱变化规律研究

Study on Regularity of Berberine in Various Organs of Three Kinds of Berberis in Different Latitude of Qinghai Province

为了研究青海3种小檗属植物小檗碱含量随纬度的变化规律,采用2010年版中华人民共和国药典中三颗针的测定方法测定小檗碱含量。结果表明,西北小檗各部位小檗碱的含量随纬度降低呈现出升高的趋势,鲜黄小檗则随纬度降低而减少,直穗小檗随纬度的降低而呈现先降低后增加的趋势。

Along with changes of latitude,we studied the change regularity of berberine with three kind of Berberis in Qinghai province,and used the method for the determination of Sankezhen,which was from the people＇s Republic of China Pharmacopoeia 2010 Edition to determine the contents of berberine in various organs of three kinds of Berberis grown in different latitude. The results showed that the contents of berberine in medicinal parts of Berberis vernae showed increasing trend with latitude decrease,the contents of berberine of Berberis diaphana showed the increasing trend with latitude increase,the contents of berberine of Berberis dasystachya showed first increasing then decreasing trend with the latitude increase.
