摘要: |
目的 建立盐酸达泊西汀片剂中异构体的HPLC检测方法。方法 采用DAICEL CHIRALPAK OZ-H色谱柱(250 mm×4.6 mm,5 μm),柱温:40℃,检测波长:293 nm,流速:1.0 mL·min-1,流动相:正己烷-异丙醇-二乙胺(80:20:0.05)。结果 盐酸达泊西汀及其异构体在0.01~0.50 mg·mL-1内具有良好的线性关系(r=0.999 9),盐酸达泊西汀定量限为0.002 mg·mL-1(相当于0.02%),最低检测限为0.001 mg·mL-1(相当于0.01%);异构体定量限浓度为0.001 mg·mL-1(相当于0.01%),最低检测限为0.000 5 mg·mL-1(相当于0.005%)。结论 该方法操作简便,结果准确,可用于盐酸达泊西汀片剂中异构体的含量测定。 |

Abstract: |
OBJECTIVE To establish a method of HPLC for the determination of isomer in dapoxetine hydrochloride tablets. METHODS The column of DAICEL CHIRALPAK OZ-H (250 mm×4.6 mm, 5 μm) was used. Column temperature was 40℃, detection wavelength was 293 nm, flow rate was 1.0 mL·min-1, and the mobile phase consisted of n-hexane-isopropanol-diethylamine(80:20:0.05). RESULTS The calibration curves of dapoxetine hydrochloride and isomer were linear over the range of 0.01-0.50 mg·mL-1(r=0.999 9). The limit of quantification was 0.002 mg·mL-1(equivalent to 0.02%). The minimum detection limit was 0.001 mg·mL-1(equivalent to 0.01%). The limit of quantification of isomer was 0.001 mg·mL-1(equivalent to 0.01%), and the minimum detection limit was 0.000 5 mg·mL-1(equivalent to 0.005%) CONCLUSION The method is proved to be simple and accurate, which is suitable for the content determination of optical isomer in dapoxetine hydrochloride tablets. |
