ABSTRACT: Andrographis paniculata Nees. (say-gha-gyi) is a medicinal plant tradition-ally used as hepatoprotective agent and grows wild throughout Myanmar. The aim of this study was to evaluate scientifically the hepato-protective effect of Andrographis paniculata Nees. leaves on paracetamol-induced hepatotoxicity in albino rats. Andrographis paniculata Nees. leaves were extracted with 50% ethanol. To induce hepatotoxicity, oral paracetamol(0.5 g/kg) was used. To investigate hepatoprotective effect, thirty albino rats (250-300 g) were divided into five groups, group I served as normal control (distilled water only), group II was kept as paracetamol control and group III, IV and V served as tested groups, receiving oral administration of 200, 300 and 400 mg/kg of the 50% ethanol extract, respectively, daily up to 7th day. On the morning of 7th day, group II, III, IV and V received single dose of oral paracetamol (0.5 g/kg). After 48 hours of paracetamol admini-stration, the animals of all groups were sacrificed, and blood was collected. All doses of the ethanolic extract of Andrographis paniculata Nees. showed significantly lower ALT level than paracetamol control (p<0.001). Signifi-cant lower AST level than paracetamol control group was found with high dose of the extract 300 and 400 mg/kg receiving groups (p<0.001) and 200 mg/kg receiving group (p<0.01). High dose of extract 300 and 400 mg/kg receiving groups showed significant hepatoprotective effect in degeneration of liver when compared with paracetamol control (p<0.05). From these data, it showed that the 50% ethanolic extract of Andrographis paniculata Nees. leaves has some extent of hepatoprotective effect on paracetamol-induced hepatotoxicity in albino rats.
