OBJECTIVE To establish a method for the determination of thecontent of all-trans-retinoic acid (ATRA) soft gelatin capsule. METHODS An HPLC method was utilized, ATRA was seperated on a μBondapak C18 column(10 μm,3.9 mm×300 mm) and detected at 340 nm,using methanol-NH4Ac buffer(85∶15) as the mobile phase, the flow rate was 0.8 ml·min-1,the column temperature was kept at 22 ℃.RESULTS The calibration curve was linear within the range from 41.04 to 287.28 μg·ml-1,Y=-958506.49X+110375.98,r=0.9994 (n=7),the average recovery was 98.58%,RSD=1.56%(n=5).CONCLUSIONS This method is accurate and reproducible.
