Averrhoa bilimbi L, Serotonin (5-HT), 5-HT3 receptor, Ethanolic extract


Objective: The study was aimed to investigate the relaxation effect of ethanolic extract of Averrhoa bilimbi L. leaves (EEABL) and ondansetron against 5-HT-induced contraction of the 5-HT3 receptor.

Methods: The study of the relaxation effect of the cumulative concentration EEABL leaves (0.5–4 mg/mL) and ondansetron (10−5–3×10−2) after the contracted with 5-HT (EC80: 1.158×10−6 M) was conducted in vitro using isolated rat's ileum organ in the Tyrode solution.

Results: The EEABL and ondansetron decreased ileum contraction after induced by 5- HT. EEABL has no difference in terms of ability as ondansetron in reducing the ileum smooth muscle contraction induced by 5-HT (p>0.05).

Conclusion: The EEABL has relaxation effect on smooth muscle of rat's isolated ileum which has induced by 5-HT.
