Abstract
Objective: To investigate the modulating role of methanol extract of Tephrosia vogelii leaves on acetylcholine (ACh)-induced contraction of isolated rabbit jejunum.
Methods: Rabbit jejunum segment was removed and placed in an organ bath containing Tyrode's solution, and its contractions were recorded isometrically.
Results: ACh (2.0 × 10−10 g/mL) and the extract (2.0 × 10−4 g/mL) individually increased the frequency of contraction (mean ± SEM) of the isolated smooth muscle tissue by 47.6% ± 9.5% and 77.8% ± 66.5%, respectively. When ACh and the extract were combined, the frequency of contraction of the tissue was increased by 222.2% ± 25.9%, representing a 366.7%-increase (P < 0.001) over the effect of ACh alone. Similarly, ACh (2.0 × 10−9 g/mL) and the extract individually increased significantly (P < 0.001) the amplitude of contraction of the tissue by 685.7% ± 61.1% and 455.2% ± 38.1%, respectively. When ACh and the extract were combined, the amplitude of contraction of the tissue rose by 1263.8% ± 69.0%, representing 84.3% increase over the effect of ACh alone.
Conclusions: The findings demonstrate that methanol extract of Tephrosia vogelii leaves potentiates the contractile effect of ACh on intestinal smooth muscle, supporting the traditional claim that the plant is purgative.
Objectif : Étudier le rôle modulateur de l'extrait méthanolique de feuilles de *Tephrosia vogelii* sur la contraction induite par l'acétylcholine (ACh) sur le jéjunum isolé de lapin.
Méthodes : Un segment de jéjunum de lapin a été prélevé et placé dans un bain à organe contenant une solution de Tyrode, et ses contractions ont été enregistrées de manière isométrique.
Résultats : L'ACh (2,0 × 10⁻¹⁰ g/mL) et l'extrait (2,0 × 10⁻⁴ g/mL) ont augmenté individuellement la fréquence de contraction (moyenne ± ESM) du tissu musculaire lisse isolé de 47,6 % ± 9,5 % et de 77,8 % ± 66,5 %, respectivement. Lorsque l'ACh et l'extrait ont été combinés, la fréquence de contraction du tissu a augmenté de 222,2 % ± 25,9 %, ce qui représente une augmentation de 366,7 % (P < 0,001) par rapport à l'effet de l'ACh seule. De même, l'ACh (2,0 × 10⁻⁹ g/mL) et l'extrait ont augmenté de manière significative (P < 0,001) et individuelle l'amplitude de contraction du tissu de 685,7 % ± 61,1 % et de 455,2 % ± 38,1 %, respectivement. Lorsque l'ACh et l'extrait ont été combinés, l'amplitude de contraction du tissu a augmenté de 1263,8 % ± 69,0 %, représentant une hausse de 84,3 % par rapport à l'effet de l'ACh seule.
Conclusions : Ces résultats démontrent que l'extrait méthanolique de feuilles de *Tephrosia vogelii* potentialise l'effet contractile de l'ACh sur le muscle lisse intestinal, étayant ainsi l'allégation traditionnelle selon laquelle cette plante possède des propriétés purgatives.
