Cultivation of Plasmodium Falciparum And Antiplasmodia Screening of Methanol Extract of Ocimum Basilicum (Scent Leaf)

ABSTRACT

The methanol extract of Ocimum basilicum (Scent leaf) was greenish in colour and increases in concentration through evaporation process which turns the extract to thick and dark green colouration. The percentage parasitaemia growth increases consecutively for seven (7) days with 7th day result having the highest parasite growth of 18.73%. The antimalarial activity of methanol extract of Ocimum basilicum conducted at six (6) different concentration (µg/ml) value shows that the highest % mean inhibition value of 58.81 was achieved at concentration of 200 µg/ml. The inhibition concentration (IC50) value was found to be 110µg/ml determined through linear interpolation from the inhibition curve with regards to the concentration. The mean inhibition for schizont maturation increases with increase in concentration of the extract relative to control. Therefore methanol extract of Ocimum basilicum exhibits a moderate antimalarial activity.
