Abstract


ABSTRACT
The bitter leaf extract (Andrographis paniculata Ness.) has long been known as an anti-malarial.
Our previous research has developed a bitter leaf hydrotrophy extract (BLHE) using a sodium
acetate 2 mol/L as a hydrotop compound solution. The extraction process lasts for 2 hours, faster
than conventional extraction. The result is two types of BLHE with different stirring temperatures,
at 30°C (BLHE1) and 35°C (BLHE2). This study meant to determine and compare the in vitro antiplasmodial activity BLHE1 and BLHE2. The anti-plasmodial activity of BLHE1 and BLHE2 (0.1-
50.0) g/mL performed on a G-2300 strain of P. falciparum (chloroquine-resistant) after incubated
for 48 hours (triplicate). The percentage of parasitemia determined through an examination of
blood smears stained with Giemsa. The percentage of growth inhibition of P. falciparum evaluates
by comparing percentage of growth with the control group and IC50 determine by probit analysis.
The results showed that BLHE1 and BLHE2 respectively were able to inhibit the growth of P.
falciparum of 14.62% - 43.25% (IC50: 59.689 μg/mL) and 24.06% - 49.48% (IC50: 44.541 μg/mL). Based on these data, BLHE should produce with sodium acetate 2 mol/L, with stirring at 35°C,
because this condition will obtain BLHE that active as anti-plasmodial.
Keywords: Anti-plasmodial, bitter leaf hydrotrophy extract, P. falciparum strain G-2300, in
vitro
