不同产地常山饮片及其提取物中常山碱含量的测定

Determination of febrifugine content in radix dichroae drinking tablets and its extracts from different places of origin

为了评估不同产地常山饮片中常山碱含量的差异,试验采用稀盐酸酸化、超声波萃取技术制备常山提取物,采用紫外分光光度法测定常山饮片及其提取物中常山碱的含量。结果表明:四川和甘肃两个产地常山饮片中常山碱的含量均很低,但前者相对高。说明常山产地不同,常山碱含量有较大差异;应用超声波萃取技术提取、分离常山碱,具有操作简单、提取率高的特点。

To evaluate the different：e of febrifugine content in radix dichroae drinking tablets from different places of origin, tile tebrifugine ex- tract were prepared by dilate hydrochlorie aeid and ultrasonic extraction technique, and then the febrifugine contents in radix dichroae drinking tablets and its extracts were assayed by ultraviolet spectrophotometry. The results showed that febrifugine eontents origined from Siehuan and Gansu drinking tablets were low, but the tbrmer was higher than the latter relatively. The results suggested that there was a differenee in the febrio fugine content beeause of the different places of origin. Ultrasonie extraction technology is applied to extract and separate febrifugine, which has advantages of simple operation and higher extraction rate.
