| Abstract: | The glycyrrhetic acid in tooth paste was determined by RP-HPLC. A YWG-C18 column was employed in the procedure. By formaldehyde -0.01 mol/L KH2 PO4 (85:15) as the mobile phase at a flow rate of 1.0 mL/min, the sample was separated and detected at 254 nm with an UV detector. The recovery obtained is in the range of 99.61%-101 .67% . The RSD was 1.85%-3.16% . The present method is simple, rapid and accurate. |
