| 摘要: |
| 目的 探讨中国特色饮食豆浆对豆科中药吸收的影响，指导临床用药期间合理饮食。方法 采用药动学研究豆浆对豆科中药葛根、黄芪、甘草和槐花中代表性功效成分（黄酮类）体内吸收的影响；在体肠灌流考察豆浆对功效成分肠吸收的影响及其随时间的变化规律；外翻肠囊法和酶抑制剂法考察P-gp和MRP2蛋白在此过程中的作用；UHPLC-QQQ-MS/MS检测血浆和肠液中葛根素、芦丁、甘草苷和刺芒柄花素的含量，计算各成分在大鼠药动学参数、各肠段的累计吸收量和吸收速率常数。结果 豆浆显著降低各功效成分在大鼠体内的AUC0-t，Cmax，豆浆和药液同时灌流可显著抑制4个功效成分在各肠段的吸收，预灌流豆浆2 h也显著抑制葛根素、刺芒柄花素、甘草苷的吸收，预灌流0.5 h和1 h再灌流药液对各功效成分吸收无显著影响。维拉帕米和丙磺舒对这4种成分的累计吸收量、吸收速率常数和表观渗透率无显著影响。结论 豆浆显著抑制了葛根、黄芪、甘草、槐花中黄酮类成分在大鼠体内的吸收转运，此作用可能和P-gp、MRP2无关，具体的作用机制仍需进一步研究。服用含豆科中药的药物时应避免同时服用大豆类食物。 |

| Abstract: |
| OBJECTIVE To determine the effect of Chinese dietary soybean milk on intestinal absorption of legume traditional Chinese medicine, and to guide the rational diet during clinical medication. METHODS Pharmacokinetics was used to study the effect of soybean milk on the absorption in vivo of the representative flavonoids of Puerariae lobatae radix, Astragali radix, Glycyrrhiza radix et rhizoma and Sophorae flos. In vivo inte stinal perfusion was used to study the effect of soybean milk on the absorption of the effective ingredients and its change rule with time. Eversion intestinal sac method and enzyme inhibitor method were used to study the effect of P-gp and MRP2 protein in this process. UHPLC-QQQ-MS/MS method was used to detect the contents of puerarin, rutin, glycyrrhizin and anthocyanin in plasma and intestinal fluid and the pharmacokinetic parameters, cumulative absorption capacity and absorption rate constant of each component in rats were calculated. RESULTS Soybean milk significantly reduced the AUC0-t, Cmax of the functional components in rats. The simultaneous perfusion of soybean milk and liquid medicine could significantly inhibit the absorption of the four functional components in each intestinal segment. The pre-perfusion of soybean milk for 2 h also significantly inhibited the absorption of puerarin, anthocyanin and glycyrrhizin. The pre-perfusion of 0.5 h and 1 h had no significant effect on the absorption of the functional components. Verapamil and probenecid had no significant effect on the cumulative absorption, absorption rate constant and apparent permeability of the four components. CONCLUSION Soybean milk significantly inhibit the absorption and transport of flavonoids from Puerariae lobatae radix, Astragali radix, Glycyrrhiza radix et rhizoma and Sophorae flos in rats in vivo, which may not be related to P-gp and MRP2. The specific mechanism of action needs further study. When taking drugs containing legumes, it is avoided to taking soybean milk at the same time. |
