Abstract
Purpose: To
evaluate the possible hypoglycaemic, hypolipidemic, and
antioxidant activities of Ardisia compressa (AC) on a
rat model of type 2 diabetes.
Methods:
Diabetes was induced in female Wistar rats by
intraperitoneal (i.p.) administration of streptozotocin
(65 mg/kg) and nicotinamide (120 mg/kg). The diabetic
animals were orally administered water with or without
metformin 150 mg/kg (D+Met) or 100, 200, or 400 mg/kg AC
(D+100, 200 or 400), daily for 21 days. Normoglycaemic
animals were given water with or without 400 mg/kg AC.
Glycaemia, urinary protein excretion, lipid profiles,
and antioxidant activity were determined.
Results: AC decreased hyperglycaemia in
diabetic animals (150.67 ± 13.41 mg/dL, AC vs. 346.33 ±
51.21 mg/dL, Diabetes), but not hyperlipidemia. An
antioxidant effect was also observed in the 400-mg/kg AC
extract group, which exhibited significantly decreased
lipid peroxidation (2.597 ± 0.284, AC vs. 3.623 ± 0.280
μM malondialdehyde [MDA]/g, Diabetes) and reactive
oxygen species (ROS) production (1.533 ± 0.207, AC vs.
5.281 ± 0.457 μg DCF/mg, Diabetes) in liver. In
addition, lipid peroxidation, ROS, and oxidised proteins
levels were decreased in the kidneys and pancreas of AC
treated diabetic animals.
Conclusion: AC leaves exert hypoglycaemic and
antioxidant effects in type 2 diabetic rats, and has the
potential to delay or prevent the onset of
diabetes-induced complications.
