ABSTRACT
Objective:To determine the content of magnolol and honokiol in KAIXIONG SHUNQI CAPSULE by HPLC.Methods:Separation was achieved on a Nova Pak C 18 column. The mobile phase was metanol water(78∶22), the wavelength of the UV detector 294nm.Results:Linear range of megnolol and honokiol were 0.08?g 0.4 ?g and 0.052?g 0.26?g, respectively. The average recovery was 100.22% ( RSD =1.21%).Conclusion: The method was accurate and reliable.
ABSTRACT
Objective:To establish the content standards of Cortex Magnoliae Officinalis with ginger mix frying by determing the change of total content of magnolol and honokiol in Cortex Magnoliae Officinalis before and after ginger mix frying. Methods: The total content of magnolol and honokiol in Cortex Magnoliae Officinalis before and after ginger mix frying were determined by HPLC according to the determination method of Cortex Magnoliae Officinalis in China Pharmacopeia (2000). Results: There was 13-14% decrease in total content of magnolol and honokiol of Cortex Magnoliae Officinalis after ginger mix frying. Conclusions: It is suggested that the total content of magnolol and honokiol of Cortex Magnoliae Officinalis after ginger mix frying shouldn't lower than 1.6%.
