目的:研究乌蕨醇提物在肠道中的吸收特性。方法:采用大鼠外翻肠囊实验模型,收集高、中、低质量浓度乌蕨醇取物给药后不同时间点的肠囊吸收液;采用高效液相色谱法检测肠囊吸收液样品中原儿茶酸、原儿茶醛、牡荆苷3种化学成分含量,计算吸收动力学参数(Q、Ka),考察各成分肠吸收特征。结果:原儿茶酸、原儿茶醛、牡荆苷3种成分在乌蕨醇提物中能被检测出,但在其肠吸收液中未被检测到。结论:在本研究实验条件下,肠道对乌蕨中原儿茶酸、原儿茶醛、牡荆苷3种指标性成分未有吸收,具体原因还有待进一步实验探究。 |

Objective: To study the absorption characteristics of alcohol extract of Odontosoria chinensis in intestine. Methods: The experimental model of everted intestinal sac in rats was used to collect the intestinal sac absorption solution at different time points after administration of high, medium and low mass concentrations of alchol extract of Odontosoria chinensis; the contents of protocatechuic acid, protocatechuic aldehyde and vitexin in intestinal sac absorptionsolution samples were detected by HPLC. The absorption kinetic parameters (Q, KA) were calculated to investigate the intestinal absorption characteristics of each components. Results: Protocatechuic acid, protocatechuic aldehyde and vitexin could be detected in the alcohol extract of Odontosoria chinensis, but not in its intestinal sac absorption solution. Conclusion: Under the experimental conditions of this study, the intestinal tract don't absorb protocatechuic acid, protocatechuic aldehyde and vitexin, and the specific reasons need to be further explored. |
