摘 要:采用大鼠外翻肠囊模型,研究扶正消症方中小檗碱、巴马汀、黄连碱、表小檗碱4种黄连碱在大鼠不同肠段的吸收情况,计算各成分的吸收参数,用SPSS 20.0统计学软件对数据进行分析处理,分析其在不同肠段的吸收特征。结果显示,各生物碱成分在不同肠段的吸收均符合零级吸收速率;4种生物碱成分在低剂量时的吸收速率常数(Ka)与中、高剂量比较有显著性差异(P<0.05),但是中剂量与高剂量比较Ka并没有明显差异。扶正消症方提取物不同剂量时,4个生物碱在不同肠段的吸收方式除被动扩散外还存在主动转运。4个生物碱在回肠中的吸收量略高于空肠,但无显著性差异,表明这4个生物碱在小肠无特定吸收窗。Everted intestinal sac models were used to investigate the intestinal absorption of the 4 alkaloids(berberine, paimatine, coptisine, and epiberberine) in Fuzheng Xiaozheng Fang(FZ) at different intestine segments. The absorption parameters of each component were calculated ; SPSS 20.0 software was used to analyze the data and evaluate the absorption characteristics at different intestinal segments. The resuhs showed that all the four active ingredients conformed to zero-order absorption rate. There was significant difference in absorption rate constant (Ka) between the four ingredients at low dose and medium and high dose groups( P 〈 0. 05 ), but there was no significant difference in Ka between medium dose and high dose. The absorption mechanization of four ingredients presented two absorption manners: positive diffusion and passive absorption. The absorptive amount of 4 alkaloids in ileum was slightly greater than that of jejunum, but no significant differences were observed, which indicated that these four alkaloids had no specific absorption windows in intestinal segment.
