摘要
目的研究中药钩藤在煎剂中后下的机理。方法取两份钩藤样品,分别用水煎。一份煎煮15 min,另一份煎煮60 min,然后采用高效液相色谱进行分析。结果通过分析和紫外光谱比对,发现煎煮过程中有3个成分消失,有2个成分生成。结论钩藤久煎无力可能是因为在煎煮过程中降压有效成分被破坏,而被破坏的3个成分很可能就是钩藤降压有效成分。
Aim To investigate the mechanism of chemical change during the decoction of uncaria hook.Methods Two sample of uncaria hook were prepared,one was decocted in 15 min.and the other decocted in 60 min.The samples were analyzed by HPLC.Results Compared with the analytical results of two samples,three constituents were disappeared during the decoction,while two new constituents were created during the process three.Conclusion There were the chemical changes in the decoction of uncaria hook.The active constituents of uncaria hook might be the constituents that disappeared during the decoction.
