Abstract
OBJECTIVE To establish a method of quality control for Jierekangyan No.1(JRKY) oral solution by qualitatively and quantitatively determining the active substance of magnolol in the solution.METHODS Analyse magnolol qualitatively by TLC and quantitatively on ODS-C18 column with MeOH-water(70:30) as mobile phase,to determine the content of magnolol by HPLC.RESULTS The average recovery was 98.15%(RSD=2.96%).The linear concentration range of the method was 0.0148～0.148μg/ml, r =0.9996.CONCLUSION The qualitative and the quantitative methods studied are rapid,reliable and sensitive.
