Effect of Curcuma longa L, Zingiber officinale Roscoe, Lupinus mutabilis Sweet and Myrciaria dubia(Kunth) McVaugh foods on the in vitro inhibition of alpha-glucosidase
Abstract
Introducción. A medida que se acepta más el rol de la alimentación en la salud humana, se presta con más frecuencia atención a los ingredientes bioactivos de algunos alimentos, en el presente estudio se evaluará el efecto antidiabético de dos especias, una legumbre y un fruto. Objetivos. Determinar la capacidad inhibitoria in vitro de cuatro alimentos sobre la α-glucosidasa, una enzima involucrada en la hiperglicemia postprandial. Materiales y métodos. Mediante el ensayo de inhibición de la enzima α-glucosidasa se evaluaron diferentes concentraciones de cada alimento para establecer la concentración inhibitoria media (IC50) y compararlos con el fármaco control acarbosa usando las pruebas ANOVA y post hoc de Dunnett. Resultados. La IC50 del extracto acuoso y etanólico de Curcuma longa fueron 171,60±15,91 μg/mL y 81,90 ± 19,73 μg/mL; respectivamente y ambos diferentes a acarbosa (p<0,05); del extracto acuoso y etanólico de Zingiber officinale fueron >1000 μg/mL y 191,27 ± 19,23μg/mL, diferente a acarbosa (p<0,05); del extracto acuoso y etanólico de Lupinus mutabilis fueron ambos superiores a 1000 μg/mL; del extracto acuoso y etanólico de Myrciaria dubia, 50,78±5,13 μg/mL y 14,46±2,98 μg/mL, respectivamente y ambos diferentes a acarbosa (p<0,05); la acarbosa mostró un IC50: 878,17±17,30 μg/mL. Conclusiones. Los alimentos evaluados inhibieron la enzima α-glucosidasa, excepto los extractos de L. mutabilis y el extracto acuoso de Z. officinale. Introduction. As the role of food in human health gains acceptance, more attention
is being paid to the bioactive ingredients of some foods. The present study will evaluate
the antidiabetic effect of two spices, a legume and a fruit. Objective. To determine the in
vitro inhibitory capacity of four foods on α-glucosidase, an enzyme involved in postprandial
hyperglycemia. Materials and methods. Using the α-glucosidase enzyme inhibition assay,
different concentrations of each food were evaluated to establish the half-maximal inhibitory
concentration (IC50) and compare them with the control drug acarbose using ANOVA and
Dunnett›s post hoc tests. Results. The IC50 of aqueous and ethanolic extract of Curcuma
longa were 171.60±15.91 μg/mL and 81.90 ± 19.73 μg/mL; respectively and both different
from acarbose (p<0.05); of aqueous and ethanolic extract of Zingiber officinale were >1000
μg/mL and 191.27 ± 19.23μg/mL, different from acarbose (p<0.05); from aqueous and
ethanolic extract of Lupinus mutabilis were both >1000 μg/mL; from aqueous and ethanolic
extract of Myrciaria dubia, 50.78±5.13 μg/mL and 14.46±2.98 μg/mL, respectively and
both different from acarbose (p<0.05); acarbose showed an IC50: 878.17±17.30 μg/mL.
Conclusions. The foods evaluated inhibited the α-glucosidase enzyme, except the extracts of
L. mutabilis and the aqueous extract of Z. officinale.
