          摘  要  目的  探讨芍药甘草汤自组装纳米粒(SGD-SAN)形成对其主要活性成分肠吸收行为的影响及机制。方法  制备 SGD-
          SAN 并进行表征;采用大鼠在体单向肠灌流模型,以吸收速率常数(Ka )和表观渗透系数(Peff )为指标,以游离药物为对照,探讨
          SGD-SAN中5种活性成分(芍药内酯苷、芍药苷、芹糖甘草苷、甘草苷、甘草酸)在空肠和回肠的吸收特性;在较佳吸收肠段考察药
          物浓度及外排转运蛋白抑制剂(P糖蛋白抑制剂维拉帕米、多药耐药相关蛋白2抑制剂吲哚美辛、乳腺癌耐药蛋白抑制剂利血平)
          对上述成分肠吸收特性的影响。结果  所得SGD-SAN呈球状且大小均一,平均粒径为(155.57±2.65)nm,多分散性指数为0.34±
          0.03,Zeta电位为(-9.30±1.12)mV;芍药内酯苷等5种活性成分的平均总含量为12.26%,且不受酶降解和肠道物理吸收的影响。
          与游离药物组比较,SGD-SAN组中5种成分在回肠段均表现出更高的吸收速率,且在回肠段中的Ka和Peff (回肠段中甘草酸的Peff
          除外)均显著升高(P<0.05或P<0.01),其吸收具有浓度依赖性趋势。游离药物组中,各成分的吸收均受相应抑制剂的调控(P<
          0.05或P<0.01);而在SGD-SAN组中,除芍药内酯苷和芍药苷外,其余成分均不受抑制剂的影响(P>0.05)。结论  SGD-SAN能
          够显著改善芍药内酯苷等活性成分的肠道吸收效率,上述促吸收作用可能与规避外排转运蛋白影响、兼具混合吸收模式有关。

          ABSTRACT   OBJECTIVE  To  investigate  the  effect  and  mechanism  of  self-assembled  nanoparticles  from  Shaoyao  gancao
          decoction (SGD-SAN)  on  the  intestinal  absorption  behavior  of  its  main  active  components.  METHODS  SGD-SAN  was  prepared
          and  characterized.  Using  an  in-situ  single-pass  intestinal  perfusion  model  in  rats,  the  absorption  characteristics  of  five  active
          components (albiflorin,  paeoniflorin,  liquiritin  apioside,  liquiritin,  glycyrrhizic  acid)  from  SGD-SAN  in  the  jejunum  and  ileum
          were  studied,  with  the  absorption  rate  constant (Ka )  and  apparent  permeability  coefficient (Peff )  as  indicators,  and  compared  with
          free drugs. In the intestinal segment with optimal absorption, the effects of drug concentration and efflux transporter inhibitors (P-
          glycoprotein  inhibitor  verapamil,  multidrug  resistance-associated  protein  2  inhibitor  indomethacin,  breast  cancer  resistance  protein
          inhibitor reserpine) on the intestinal absorption characteristics of these components were examined. RESULTS  The obtained SGD-
                                                             SAN exhibited a spherical shape with uniform sizes, an average
