【摘要】 目的:研究川芎、炮姜超临界CO2提取物透皮凝胶(简称芎姜超临界CO2提取物凝胶)的经皮渗透性。方法:通过透皮扩散仪测定芎姜超临界CO2提取物凝胶经离体大鼠皮肤的渗透性,分别以藁本内酯、6-姜酚为指标成分,高效液相色谱(HPLC)法测定药物含量求算累积渗透量(Q)与稳态透皮速率(JS)。结果:芎姜超临界CO2提取物凝胶中藁本内酯和6-姜酚均能有效经皮渗透,Js分别为(47.57±3.77)、(8.29±1.47)μg/(cm2·h),14 h平均累积渗透百分数分别为(26.99±1.89)%和(14.40±1.18)%。结论:芎姜超临界CO2提取物凝胶具有良好的经皮渗透性,经皮给药有望作为芎姜超临界CO2提取物的一种新给药途径。更多还原

【Abstract】 OBJECTIVE:To study the transdermal permeation of hydrogel containing CO2-SFE of Ligusticum chuanxiong and Zingiber officinale(called Hydrogel containing Xiongjiang CO2-SFE for short). METHODS:The transdermal permeation of Hydrogel containing Xiongjiang CO2-SFE was determined by transdermal diffusion device,with ligustilide and 6-shogaol as indicators. Accumulative transdermal quantity and static percutaneous rate of drugs were determined by HPLC. RESULTS:The results showed that ligustilide and 6-shogaol could both permeate across the rat skin in vitro;static percutaneous rate of them were(47.57±3.77)μg/(cm-2·h)and(8.29±1.47)μg/(cm2·h);14 h average accumulative permeation percentages were(26.99±1.89)% and(14.40±1.18)%,respectively. CONCLUSIONS:The results show good transdermal permeation of Hydrogel containing Xiongjiang CO2-SFE. The percutanous administration is a potential route of administration for Xiongjiang CO2-SFE.更多还原
