Method for measuring content of active ingredients in preparation containing apremilast |
| abstract |
The invention belongs to the technical field of drug analysis and detection, and particularly relates to a method for determining the content of active ingredients in an apremilast-containing preparation, which is to determine by adopting a high performance liquid chromatography, wherein the specific liquid phase conditions are as follows: shimadzu SPD-20A; a chromatographic column: hypersil BDS reverse C18 column (5 μm,4.6 mm. times.250 mm); ultraviolet detection wavelength is 230 nm; column temperature: room temperature; mobile phase methanol to water (pH =3.5 phosphoric acid solution) =54: 46; sample introduction amount: 20 ul; flow rate: 0.8 ml/min. The HPLC detection method has strong specificity, and the auxiliary materials do not interfere with the detection of Apremilast; the method can conveniently, accurately and reliably measure the content of the apremilast and truly reflect the quality of the product. |
