| Abstract: | Objective To establish a method for the content determination of Rosmarinic acid in Origanum vulgareL. Methods The content of Rosmarinic acid was detected by HPLC. The separation was carried out on a Kromasil C18 column （150 mm×4.6 mm, 5 μm）. The mobile phase was Methanol -1.5% Acetic acid solution （38 ： 62）; the flow rate was 1.0 mL/min; the detective wavelength was set at 330 nm. The column temperature was 25 ℃. Results The calibration curve showed good linearity over the range of 0.332 1-1.660 5 μg （r =0.999 9）. The average recovery was 98.96% with RSD 1.09% （n =6）. The content of Rosmarinic acid in Origanurn vulgare L. from 10 different regions were between to 8.13-15.74 mg/g. Conclusion This method was rapid, accurate, reliable; it could be used as a determination of Rosmarinic acid in Origanurn vulgare L. |
