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
