Abstract
This study was carried out to investigate the anti-malarial activity of Juniperus chinensis by in vitro and in vivo system using Plasmodium falciparum chloroquine-sensitive(3D7) and P. falciparum chloroquine-resistant(S20) strains. According to cytotoxicty test on NIH 3T3 cell, the ethanol extract(EtOH), ethylacetate(EtOAc) fraction and aqueous fraction possessed significant anti-malarial activity against both 3D7 and S20 strains at non-toxic concentrations(less than100 /). In vitro assay, EtOAc fraction showed notable activity against 3D7 and S20 strains of P. falciparum with IC∧50 values of 37±2 ㎍/ml and 36±6 ㎍/ml. In animal test using P. falciparum infected human erythrocytes, the treatment of EtOAc fraction significantly inhibited parasitaemia in mice in a dose-dependent manner that is parasitaemia of 42%, 34% and 31% in doses of 10 mg/kg, 20 mg/kg and 40 mg/kg, respectively. The study provides data to support the medicinal importance of the J. chinensis.
