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).
Materials and 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.
Conclusion:
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.
