# Physicochemical Design and In Vitro Evaluation of Diterpene Phytol-Loaded Solid Lipid Nanoparticles

## TL;DR

Researchers developed stable nanoparticles to deliver phytol, a natural compound with health benefits, showing effective encapsulation and controlled release.

## Contribution

A new lipid matrix from Platonia insignis was used to create stable, spherical solid lipid nanoparticles for phytol delivery.

## Key findings

- Nanoparticles with sizes under 300 nm showed high encapsulation efficiency (>90%).
- The nanoparticles enabled slow release and dose-dependent cytotoxic effects of phytol.
- The lipid matrix (TG1) proved effective for creating stable phytol-loaded nanoparticles.

## Abstract

Phytol (PHY) is a
water immiscible natural diterpene with interesting
pharmacologic and antioxidant properties with great potential for
application in foods, cosmetics, and pharmaceuticals. In this letter,
a natural 1,3-distearyl-2-oleyl glycerol (TG1) extracted from Platonia insignis Mart was explored as a lipid matrix for
preparing uniformly sized and stable PHY-loaded solid lipid nanoparticles
(SLN). Different tested compositions induced spherical (<300 nm),
stable SLN with high encapsulation efficiency (>90%), able to induce
slow release and a dose-dependent cytotoxic effect of PHY. These achievements
corroborated with a promising nanocarrier for PHY and are able to
be tested in different application fields.
