ABSTRACT

Background:

Momordica charantia is a vine, native to tropics and subtropics that has found use in herbal medicine. In Nigeria, the plant is locally used in the treatment of diabetes.

Objective:

To investigate the inhibitory effect of terpenoid-rich extract from Momordica charantia on α-glucosidase activity.

Method:

The inhibitory effect of the terpenoid-rich extract from Momordica charantia on the activity of alpha-glucosidase from Saccharomyces cerevisiae as well as the determination of the mode of inhibition were investigated using in vitro assay methods.

Results:

The results revealed that the terpenoid-rich extract had a high IC50 of 1.60 mg/mL. The Lineweaver-Burk plot revealed that the extract exhibited partially mixed­type inhibition of α-glucosidase.

Conclusions:

It can be inferred from this study that although terpenoid-rich extract inhibited α-glucosidase, further purification will be necessary on the extract so as to increase its potency as an inhibitor of α-glucosidase. The action of the extract on α-glucosidase provided an insight into the probable mechanism of action of Momordica charantia in reducing hyperglycemia.
RESUMEN
Antecedentes Momordica charantia es una vid, nativa de las regiones tropicales y subtropicales que ha sido usada en la medicina herbal. En Nigeria, esta planta se ha usado localmente en el tratamiento de la diabetes.

Objetivo:

Investigar el efecto inhibitorio del extracto rico en terpenoides de Momordica charantia sobre la actividad de la α-glucosidasa.

Método:

El efecto inhibitorio del extracto rico en terpenoides de Momordica charantia sobre sobre la actividad de la α-glucosidasa y el modo de inhibición se evaluó con un ensayo in vitro.

Resultados:

Los resultados mostraron que el extracto rico en terpenoides tiene un alto IC50 de 1,60 mg/mL. El gráfico Lineweaver-Burk reveló que el extracto presenta una inhibición combinada de la α-glucosidasa.

Conclusión:

De este estudio se infiere que aunque el extracto rico en terpenoides inhibió la α-glucosidasa, es necesario realizar una purificación con el fin de incrementar su potencia como inhibidor de la α-glucosidasa. La acción del extracto sobre la α-glucosidasa proporciona un entendimiento del mecanismo de acción probable de Momordica charantia en la reducción de la hiperglicemia.
