摘要:

运用主成分分析建立一种中药多组分经皮渗透研究的评价方法, 并将其应用于香附四物汤效应部位 (BW) 体外促渗剂的优选研究。采用改良Franz扩散池, 以大鼠离体腹部皮肤为渗透屏障, LC-MS/MS测定接受液中阿魏酸、芍药苷、芍药内酯苷、普鲁托品、延胡索乙素和四氢非洲防己碱6种成分的浓度, 应用主成分分析求得各组不同时间点的总因子得分, 以总因子得分代替浓度求得累积渗透量和稳态透皮速率等参数, 并以稳态透皮速率为指标判断不同促渗剂的促渗效果。与对照组相比, 其余各组稳态透皮速率均明显增加, 其中以4%氮酮 + 1% 丙二醇促渗效果最为明显。本文建立的方法适用于中药多组分的经皮渗透研究, 为香附四物汤的制剂研究提供了科学依据, 也为中药多组分的研究方法提供了可借鉴的思路。

In vitro transdermal delivery of the active fraction of Xiangfusiwu decoction based on principal component analysis
Abstract:

The objective of the present study was to establish a method based on principal component analysis (PCA) for the study of transdermal delivery of multiple components in Chinese medicine, and to choose the best penetration enhancers for the active fraction of Xiangfusiwu decoction (BW) with this method.  Improved Franz diffusion cells with isolated rat abdomen skins were carried out to experiment on the transdermal delivery of six active components, including ferulic acid, paeoniflorin, albiflorin, protopine, tetrahydropalmatine and tetrahydrocolumbamine.  The concentrations of these components were determined by LC-MS/MS, then the total factor scores of the concentrations at different times were calculated using PCA and were employed instead of the concentrations to compute the cumulative amounts and steady fluxes, the latter of which were considered as the indexes for optimizing penetration enhancers.  The results showed that compared to the control group, the steady fluxes of the other groups increased significantly and furthermore, 4% azone with 1% propylene glycol manifested the best effect.  The six components could penetrate through skin well under the action of penetration enhancers.  The method established in this study has been proved to be suitable for the study of transdermal delivery of multiple components, and it provided a scientific basis for preparation research of Xiangfusiwu decoction and moreover, it could be a reference for Chinese medicine research.
