Abstract
OBJECTIVE
To study the changes of active components in the root of Pueraria lobata after processing.
METHOD
Using HPLC, with a C18 column, MeOH-H2O-CHCl3(25:75:1) as mobile phase, and flow rate 1 ml/min.
RESULT
The Puerarin in different processed products of the drug is increased in content, but gets seriously destroyed if processed by carbonizing.
CONCLUSION
The Puerarin content in the root of Pueraria lobata is affected by drug-processing.
摘要
目的
研究葛根炮制后根部活性成分的变化。
方法
采用高效液相色谱法，以C18柱，甲醇-水-三氯甲烷（25:75:1）为流动相，流速为1毫升/分钟。
结果
该药物不同炮制品中葛根素含量增加，但经炭化炮制则遭到严重破坏。
结论
葛根根部的葛根素含量受炮制影响。
