To investigate the change regularity of ephedrine and glyrihhzine acid in Ephedra sinila and Glycyrrhiza uralencis pair medicines and in Maxing Shigan decoction.
The contents of ephedrine and glycyrrhizic acid were determined by HPLC in samples of E. sinica extracts, G. uralencis extracts, pair medicines extracts of Maxing Shigao decoction sinica and G. uralencis, and extracts of E. sinica.
There were no significant difference in ephedrine contents amoung different samples; the contents of glycyrrhizic acid were lower in decoctions of Maxing Shigan decoction than in G. uralencis decoction and pair medicines extracts.
Macromolecular complex was NOT formed by ephedrine and Glycyrrhizic acid in decoctions containing pair medicines of E. sinica and G. uralencis.
