Abstract

Dengue Hemorrhagic Fever (DHF) is an infectious disease caused by the dengue virus and transmitted primarily through the bite of the Aedes aegypti mosquito, the disease's primary vector. Controlling the population of this mosquito species is considered a strategic measure in preventing the spread of DHF. One potential biological control agent is the matoa plant (Pometia pinnata), a member of the Sapindaceae family widely distributed in tropical regions. This plant contains secondary metabolites such as flavonoids, tannins, and saponins, which exhibit natural insecticidal activity. This study aims to evaluate the efficacy of ethanol extract derived from the bark of P. pinnata against A. aegypti larvae. The extraction process was conducted using ethanol as a solvent, and the resulting extract was tested against mosquito larvae at concentrations of 25 ppm, 50 ppm, 70 ppm, and 90 ppm. Larval mortality data were analysed using Analysis of Variance (ANOVA) via SPSS software version 24.00. The results demonstrated that the ethanol extract of P. pinnata bark had a significant dose-dependent effect on larval mortality. These findings suggest the potential of the extract as a natural active ingredient in the formulation of plant-based larvicides, contributing to environmentally friendly and sustainable dengue vector control strategies.

Abstract

The long-term use of synthetic hypoglycemic agents is known to cause adverse side effects and induce drug resistance. Winged bean (Psophocarpus tetragonolobus L.), a traditional medicinal plant from Maluku, contains secondary metabolites such as flavonoids, saponins, and tannins, which are believed to have potential in lowering blood glucose levels. This study aimed to investigate the effect of ethanolic extract of winged bean leaves on blood glucose reduction and β-cell regeneration in the pancreas of white rats (Rattus norvegicus) as a diabetic model. Thirty rats weighing between 150–200 g were divided into five groups: Group I (negative control), Group II (positive control), and Groups III, IV, and V (diabetic rats treated with ethanolic extract of winged bean leaves at doses of 2.52 mg/g BW, 5.04 mg/g BW, and 7.56 mg/g BW, respectively). Streptozotocin (STZ) was administered to Groups II–V to induce diabetes. Rats with blood glucose levels exceeding 200 mg/dL were subsequently treated with the designated doses of the extract in Groups III–V. On the final day, blood glucose levels were measured, and pancreatic organs were harvested for histological analysis. The results demonstrated that the ethanolic extract of winged bean leaves at a dose of 7.56 mg/g BW effectively reduced blood glucose levels in diabetic rats.
