Objectives
Narrative objectives1
Macaranga tanarius (scientific name: Macaranga tanarius) grows wild south of the Ryukyu Islands. The prenylflavonoids contained in Macaranga tanarius exhibit strong antibacterial and antioxidant properties, and have been reported to have antibacterial, anti-inflammatory, antioxidant, anti-cancer properties, promote glucose uptake in skeletal muscle cells, and promote tooth germ formation.
Furthermore, Macaranga tanarius fruit ethanol extract has been shown to suppress weight gain and blood sugar levels in obese and diabetic model mice. Safety tests showed no safety issues when administered to rats and mice at 2g/kg of Macaranga tanarius fruit extract (test product). Thus, if Macaranga tanarius fruit extract is commercialized, it is expected to promote health through its anti-inflammatory, blood sugar-lowering, and anti-obesity properties. Therefore, in this study, we first conducted human safety tests.
