Objective: The purpose of this study is to simultaneously determine the content of rosmarinic acid
caffeic acid and ethyl caffeate in Melissa officinalis by RP-HPLC. Method: Hanbon Megres C18 column (4.6 mm×250 mm
5 μm) was adopted. The mobile phase consisted of formic acid-acetonitrile-water (0.5:20:80) and formic acid-methanol-acetonitrile (0.5:40:60) with gradient elution program(0-25 min
0%-45% B;25-30 min
45%-100% B;30-30.1 min
100%-0% B). The flow rate was 1.0 mL·min-1. The column temperature was set at 35℃ and the detection wavelength was 330 nm. Result: The linear ranges of rosmarinic acid
caffeic acid and ethyl caffeate were 6.0-300.0
0.15-7.5 and 0.15-7.5 mg·L-1 respectively. The average recoveries(n=6) for the sample preparation of the markers were 99.48%
99.56%
and 101.7% respectively. Conclusion: The quantitative method for rosmarinic acid
caffeic acid and ethyl caffeate by HPLC can provide the basis for quality control of M. officinalis.
