摘要:

采用体外透皮扩散池法,以离体大鼠腹部皮肤为屏障,对丁姜和胃膏贴剂透皮释药液中的丁香酚含量测定方法和不同时间段单位面积透皮累积释药量进行实验研究。结果表明,采用Agilent Zorbax SB-C18(150 mm×4.6 mm,5μm)色谱柱,甲醇-水(65∶35,V/V)为流动相,检测波长280 nm的色谱条件,丁香酚含量测定的重复性相对标准偏差为0.932%,24 h内样品溶液稳定性相对标准偏差为1.843%,平均加样回收率为97.419 2%,相对标准偏差为1.426%。透皮释药呈现一种先快后慢趋势,10 h以内累积释药总量占20 h内累积释药总量的76.71%,10~20 h内累积释药总量仅占23.29%。

Abstract:

The in vitro transdermal diffusion cell method was applied, the abdominal skin of rats in vitro was taken as the barrier, and the content determination of eugenol in transdermal solution of Dingjiang Hewei plaster and the cumulative release amount of transdermal drug per unit area in different time periods were researched. Experimental results showed the chromatographic conditions were as followed: Agilent Zorbax SB-C18 column (150 mm×4.6 mm, 5 μm), methanol-water(65∶35, V/V) as mobile phase, detection wavelength was 280 nm, the RSD of the repeatability of eugenol content was 0.932%, the RSD of sample solution stability within 24 h was 1.843%, the average recovery was 97.4192%,and its RSD was 1.426%. Eugenol transdermal drug release showed a trend of first fast, then slow. The total cumulative drug release within the first 10 h accounted for 76.71% of the total cumulative drug release within 20 h, while the accumulative release total amount within 10~20 h was only 23.29%.

Key words: isolated rat skin as barrier, Dingjiang Hewei plaster, cumulative transdermal amount per unit area, in vitro transdermal diffusion cell method, the content determination of eugenol
