BACKGROUND
Trichosanthes dioica Roxb. (Cucurbitaceae), called pointed gourd in English is a dioecious climber found wild throughout the plains of the Indian subcontinent and traditionally used in India for several medicinal purposes.
OBJECTIVE
The present study was aimed at the evaluation of in vitro antileishmanial effect of triterpenoid fraction from T. dioica root (CETD).
METHODS
The antileishmanial activity of CETD was evaluated against Leishmania donovani (strain MHOM/IN/83/AG83)) promastigotes by in vitro promastigote cell toxicity assay by using MTT (3-(4,5-dimethylthiazol-2-yl)-2,5 diphenyltetrazolium bromide). Potassium antimonyl tartrate was used as reference.
RESULTS
Here, CETD markedly inhibited the growth of L. donovani promastigotes in vitro in a concentration dependent manner and demonstrated IC50 value of 18.75 μg/ml. The reference drug potassium antimonyl tartrate exhibited IC50 of 7.52 μg/ml.
CONCLUSIONS
From the present study it can be inferred that the triterpenoid fraction of T. dioica root exhibited remarkable antileishmanial activity against Leishmania donovani promastigotes in vitro.
