Gnetum gnemon L. Seed Hardshell Nanoextract, A Potential Biomaterial for Oral AntiAging through Sirtuin-1 Induction

Keywords: nanoextract, G.gnemon, antiaging, SIRT1, acute oral toxicity

Abstract

The seeds of Gnetum gnemon L. widely referred to as melinjo, enclosed within a distinctly tough outer shell, have attracted interest due to their remarkable anti-aging capabilities. Nevertheless, despite this potential, their practical therapeutic use is limited by their naturally low solubility and restricted bioavailability. To tackle these pharmacokinetic issues, the current study utilized an environmentally friendly nanotechnology approach, specifically high-energy ball milling, to create nanoparticles from the hard shell of the seeds. This technique significantly amplifies the surface area of the bioactive particles, thus improving their absorption and efficacy within biological systems. The resulting nanoextracts were comprehensively characterized and subsequently assessed through in vivo anti-aging tests and acute oral toxicity evaluations. UVB-irradiated rats served as a biological model for simulating aging, with nanoextracts administered at doses of 36, 72, and 144 mg/kg over a duration of 12 weeks. The results demonstrated a statistically significant, dose-dependent rise in the expression of SIRT1, a crucial regulatory protein associated with cellular longevity and aging mechanisms. Notably, an acute toxicity evaluation at a dosage of 5000 mg/kg affirmed the safety of the nanoformulation, with no discernible toxic effects noted in the test subjects. These results highlight the promise of G. gnemon seed hardshell nanoparticles as a feasible and safe natural alternative for anti-aging therapies. The implementation of sustainable nanotechnology not only enhances the delivery and effectiveness of phytochemicals but also corresponds with the increasing demand for environmentally friendly biomedical advancements aimed at fostering healthy aging.
