目的:以追风活血膏为代表,研究黑膏药不同制法的化学等量性。方法:采用TLC法对不同制法的膏药中川乌、草乌、当归、没药等药材进行定性考察;用高效液相色谱法测定不同制法的膏药中士的宁和马钱子碱的含量,比较两者的等量性。结果:醇提膏药TLC能明显地检测出川乌、草乌、当归、没药,而油炸膏药TLC只能检测出没药;采用油炸法制备的追风活血膏中士的宁和马钱子碱的含量远远低于醇提法制备的膏药。其中醇提膏药中士的宁的平均含量约为油炸膏药中的9.36倍,马钱子碱的含量约为油炸膏药中的8.36倍。结论:不同制备方法的黑膏药的化学成分存在明显差异。
OBJECTIVE: To study the chemical equivalence of different preparation methods of black plaster with Herbal Ephedra as the representative. Methods: The contents of strychnine and brucine in different preparation methods were determined qualitatively by TLC method. , Compare the equivalence of the two. Results: Alcohol extract plaster TLC could obviously detect Radix Aconitum, Radix Aconiti Kusnezoffii, Angelica sinensis, Myrrh, while the TLC of fried plaster could only detect myrrh. The Dermatan and Strychnos Alkali content is much lower than the alcohol preparation of the plaster. Among them, the average content of strychnine in the alcohol extract plaster is about 9.36 times of that in the fried plaster, and the content of brucine is about 8.36 times in the fried plaster. Conclusion: There are obvious differences in the chemical constituents of black plasters with different preparation methods.
