Abstract

Objective:To study the microwave-assisted extracting method for magnolol and honokiol in Magnolia offcinalis Rend et Wils.Methods:The orthogonal design was used to study the extraction method of magnolol and honokiol.The contents of them were determined by HPLC.The methanol water glacial acetic acid(85:15:0.25)was used as a mobile phase.The flow rate was 1.0ml/min,the detection wavelength was 294nm and the column temperature was 23℃.Results:The condition of 75%ethanol with the middling power of microwave,extracting for 4 minutes and ratio of materials to liquid 1:40 was the optimal extracting method.The extracting rate of honokiol and magnolol was 92.33%,73.59%.The RP-HPLC for determining method was simple,rapid and accurate.Conclusion:The extracting and determining method was practicable for magnolol and honokiol in Magnolia offcinalis Rend et Wils.
