Malaria is infectious vector borne parasitic and Plasmodium carried by
the vector mosquitoes, which belong to genus Anopheles. The first
anti¬malarial developed later is chloroquine, primaquine, proquanil,
pyrimethamine, metloquine etc. The aim of this study is to test the
in-vitro antiplasmodial effect of extract and different fractions of
Datura innoxia (leaves) and Diospyros melanoxylan (bark). D.innoxia
(leaves) and D.melanoxylon. (barks), are collected from the lower forest
of uttarakhand which is identified by the local people.The anti-malarial
activity of the extract was discernible as number of parasite in mature
schizont form in the total of 200 parasites. The crude extract (both
water and ethanol) of D. innoxia and D. melanoxylon tested in-vitro had
show antimalarial activity. The result of this preliminary study is very
much encouraging. Natural products are important source of biologically
active compounds and have potential for the development of novel
antimalarial drugs. The eradication of the disease has been hampered by
the emergence and spread of multi drug resistant malarial parasites,
especially P.falciparum strains resistant to many antimalarial drugs.
