Background: Inhibition of carbohydrate hydrolyzing enzymes, such as α-amylase and α-glucosidase, is a key element in
the regulation of diabetes mellitus (DM). The purpose of this work was to study the inhibition of carbohydrate hydrolyzing
enzymes, and the antihyperglycemic activity of aqueous extract of Cladocolea (C. loniceroides) in streptozotocin (STZ)-induced diabetic mice.
Materials and Methods: The inhibitory activities of C. loniceroides aqueous extract on α-amylase and α-glucosidase were
investigated in vitro. Glucose tolerance test was performed in normoglycemic (NG) mice which were fed with starch or
sucrose. The effect of mistletoe aqueous extract (ME) was measured in (STZ)-induced diabetic mice. On day 35 of the
treatment, the effect of decreasing oxidative stress (lipid peroxidation, glutathione redox state, GPx and GR specific
activities, cytokines and aminotransferases analysis) was assessed.
Results: ME showed a competitive mode of inhibition for the carbohydrate hydrolyzing enzymes (CHE). The maximum
antihyperglycemic activity in mice was observed for the unripe fruit aqueous extract (UFAE) for α-amylase and stem
aqueous extract (SAE); for α-glucosidase due to the glycemic response reduction by 23% or 35%, respectively. UFAE
decreased malondialdehyde (MDA) 1.76 times; GSH/GSSG ratio was mantained (3.08 ± 0.66); GPx activity was reduced
(24%); IL-6 was reduced (18%) and the concentration of TNF-α (37%) was leveled with respect to the (STZ)-induced
diabetic mice; ALT and AST (liver transaminases) levels were nearly the same compared with those found in the NG mice.
Conclusion: UFAE of C. loniceroides exhibited the highest antidiabetic activity in (STZ)-induced diabetic mice.
