Does the triterpenoid fraction from Trichosanthes dioica root exhibit in vitro antileishmanial effect against Leishmania donovani promastigotes? Context: 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. The present study was aimed at the evaluation of in vitro antileishmanial effect of triterpenoid fraction from T. dioica root (CETD). 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. 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.
