摘要(Abstract):
考察红禾麻提取物在正常与类风湿性关节炎病理状态下大鼠体内的肠吸收特性差异,采用大鼠离体外翻肠囊模型,以红禾麻提取物5.0 g·L(-1)为吸收浓度,通过UPLC-MS/MS检测肠吸收液样品中新绿原酸、绿原酸、隐绿原酸、芦丁、山柰酚-3-O-芸香糖苷、木犀草苷、槲皮苷、异槲皮苷8种指标成分的含量,计算其累积吸收量(Q)和吸收速率常数(K_a),比较正常大鼠和类风湿性关节炎大鼠肠吸收液中红禾麻提取物各成分的吸收特征。结果表明,红禾麻提取物中8种指标成分均可吸收进入肠囊且成线性吸收,各成分的累积吸收量-时间曲线均为上升趋势,未呈饱和现象,其相关回归系数(R(-1)为吸收浓度,通过UPLC-MS/MS检测肠吸收液样品中新绿原酸、绿原酸、隐绿原酸、芦丁、山柰酚-3-O-芸香糖苷、木犀草苷、槲皮苷、异槲皮苷8种指标成分的含量,计算其累积吸收量(Q)和吸收速率常数(K_a),比较正常大鼠和类风湿性关节炎大鼠肠吸收液中红禾麻提取物各成分的吸收特征。结果表明,红禾麻提取物中8种指标成分均可吸收进入肠囊且成线性吸收,各成分的累积吸收量-时间曲线均为上升趋势,未呈饱和现象,其相关回归系数(R2)均大于0.92,符合零级吸收速率过程,推测各成分可能的吸收方式为被动扩散。正常状态下各成分以回肠吸收最好(除绿原酸外),病理状态下以十二指肠吸收最好,且8种成分在类风湿性关节炎大鼠各肠段的总体吸收优于正常大鼠,推测类风湿性关节炎可能会改变药物吸收的特定部位。实验表明类风湿性关节炎会改变红禾麻提取物的肠吸收,其作用机制有待进一步的深入研究。
This work aimed to investigate the intestinal absorption characteristics of Laportea bulbifera extract in normal and rheumatoid arthritis model rats. The contents of neochlorogenic acid, chlorogenic acid, cryptochlorogenic acid, rutin, kaempferol-3-O-rutinoside, galuteolin, quercetin and isoquercetin in intestinal absorption solution samples were detected by UPLC-MS/MS with 5.0 g·L2)均大于0.92,符合零级吸收速率过程,推测各成分可能的吸收方式为被动扩散。正常状态下各成分以回肠吸收最好(除绿原酸外),病理状态下以十二指肠吸收最好,且8种成分在类风湿性关节炎大鼠各肠段的总体吸收优于正常大鼠,推测类风湿性关节炎可能会改变药物吸收的特定部位。实验表明类风湿性关节炎会改变红禾麻提取物的肠吸收,其作用机制有待进一步的深入研究。
This work aimed to investigate the intestinal absorption characteristics of Laportea bulbifera extract in normal and rheumatoid arthritis model rats. The contents of neochlorogenic acid, chlorogenic acid, cryptochlorogenic acid, rutin, kaempferol-3-O-rutinoside, galuteolin, quercetin and isoquercetin in intestinal absorption solution samples were detected by UPLC-MS/MS with 5.0 g·L(-1) as the absorption concentration. The cumulative absorption(Q) and absorption rate constant(K_a) were calculated, and the absorption characteristics of different components of L. bulbifera in intestinal absorption solution of normal rats and rheumatoid arthritis rats were compared. The results showed that all the eight index components in the extract of L. bulbifera could be absorbed into the intestinal capsule, the cumulative absorption-time curve of each component showed an upward trend without saturation, and the correlation regression coefficient(R(-1) as the absorption concentration. The cumulative absorption(Q) and absorption rate constant(K_a) were calculated, and the absorption characteristics of different components of L. bulbifera in intestinal absorption solution of normal rats and rheumatoid arthritis rats were compared. The results showed that all the eight index components in the extract of L. bulbifera could be absorbed into the intestinal capsule, the cumulative absorption-time curve of each component showed an upward trend without saturation, and the correlation regression coefficient(R2) was greater than 0.92, which is consistent with the zero-order absorption rate process. It was speculated that the possible absorption mode of each component was passive diffusion. In normal condition, the absorption of ileum was the best(except chlorogenic acid), and in pathological condition, duodenum was the best. The total absorption of 8 components in each intestinal segment of RA rats was better than that of normal rats, which speculated that rheumatoid arthritis may change the specific site of drug absorption. The experimental results showed that rheumatoid arthritis could change the intestinal absorption of the extract of L. bulbifera, and its mechanism needs further study.
