Phytosome Supplements for Delivering

Area of Science:

• Phytochemistry
• Nanotechnology
• Pharmacology

Background:

• Gymnema inodorum (GI) is a Thai leafy green with potential for metabolic diabetic control.
• The nonpolar nature of GI's active compounds limits their bioavailability.
• Phytosome technology offers a novel approach to enhance phytonutrient delivery.

Purpose of the Study:

• To develop phytosome formulations of GI leaf extract.
• To evaluate the anti-inflammatory and anti-insulin-resistant activities of GI phytosomes.
• To assess the impact of phytosome encapsulation on GI phytonutrient bioavailability.

Main Methods:

• Formulation of GI extract into phytosomes (160-180 nm nanoparticles).
• Characterization of phytosome structure, surface charge, and phytonutrient encapsulation.
• In vitro assessment of anti-inflammatory activity (nitric oxide production in macrophages) and anti-insulin resistance (glucose uptake and lipid degradation in adipocytes).

Main Results:

• Phytosomes successfully dispersed GI extract in aqueous solution, forming spherical nanoparticles.
• GI phytocompounds were embedded within the phospholipid bilayer, altering surface charge to -35 to -45 mV.
• Phytosomes significantly enhanced the anti-inflammatory activity of GI extract but slightly diminished its anti-insulin-resistant effects.

Conclusions:

• Nano-phytosome formulation is a promising carrier for GI phytochemicals, particularly for anti-inflammatory applications.
• The phospholipid component may modulate the anti-insulin-resistant effects of GI extract.
• Further research is needed to optimize phytosome formulations for comprehensive T2DM prevention.
