Objective: To study the changes of chemical constituentsin water extracts of couplet medicines Ephedrae Herba and Atractylodis Macrocephalae Rhizomain different compatibility ratio
and to search the compatibility rule of this couplet medicines. Method: The content of five alkaloids
norpseudoe phedrine
norephedrine
ephedrine
pseudoephedrineand methyle phedrine were determined by GC-MS.The content of atractylenolide Ⅰ
atractylenolide Ⅱ
and atractylenolide Ⅲ were determined by HPLC. Result: The three compatibility ratios of Ephedrae Herba and Atractylodis Macroce phalae Rhizoma were 3: 2
3: 4
and 3: 8.Compared with decoction of Ephedrae Herba
the content of five alkaloids were decreased (P <0.05)along with the increasein the proportion of Atractylodis Macrocephalae Rhizoma. And the content of atractylenolide Ⅰ
atractylenolide Ⅱ
atractylenolide Ⅲ were also decreased (P <0.01). Conclusion: Combined Ephedra Herba with Atractylodis Macrocephalae Rhizoma
the dissolution of compounds in water extracts was inhibited with each other.
