Abstract:In this experiment,Panax notoginseng saponins chitosan nanoparticles(PNS-NPs)were prepared by self-assembly and their appearance,particle size,encapsulation efficiency,drug loading,polydispersity index(PDI),Zeta potential,and microstructure were characterized.The prepared PNS-NPs were intact in structure,with an average particle size of(209±0.258)nm,encapsulation efficiency of 42.34%±0.28%,a drug loading of 37.63%±0.85%,and a Zeta potential of(39.8±3.122)mV.The intestinal absorption of PNS-NPs in rats was further studied.The established HPLC method of PNS was employed to investigate the effects of pH,perfusion rate,and different drugs(PNS raw materials,Xuesaitong Capsules,and PNS-NPs).The absorption rate constant(Ka)and apparent permeability coefficient(Papp)in the duodenum,jejunum,ileum,and colon were calculated and analyzed.As illustrated by the results,the intestinal absorption of PNS-NPs was increased in the perfusion solution at pH 6.8(P<0.05),and perfusion rate had no significant effect on the Kaand Pappof PNS-NPs.The intestinal absorption of PNS-NPs was significantly different from that of PNS raw materials and Xuesaitong Capsules(P<0.05),and the intestinal absorption of PNS-NPs was significantly improved.
Keywords:Panax notoginseng saponins(PNS)  chitosan  oral nanoparticles  characterization  intestinal absorption
