Wound Healing, Anti-inflammatory and Antioxidant Potential of Quercetin Loaded Banana Starch Nanoparticles.

Background: Quercetin belongs to the BCS Class IV of drugs, which means it exhibits low solubility and low permeability. Quercetin is a potent antioxidant drug candidate, but it has several drawbacks, such as a short half-life, poor stability, bioavailability, and solubility. These factors affect its reliability as a good wound-healing, anti-inflammatory, and antioxidant agent. Quercetin nanoparticles resolved these problems and offered high stability, high encapsulation efficacy, sustained and prolonged release, and enhanced accumulation at target sites with high therapeutic efficacy.

Methods: Banana starch and quercetin were used to formulate a new composition of nanoparticles. Formulated QBSN were evaluated for their antioxidant, wound healing, and anti-inflammatory potential.

Results: QBSN showed a good antioxidant effect against the DPPH free radical scavenging model. Inhibition of DPPH free radicals reached up to 98 percent at 40 μl. Histopathological studies of treated tissues (wound and paw edema) confirmed the potential of QBSN.

Conclusion: In the future, prepared nanoparticles may be the choice of drug formulation for wound healing, anti-inflammatory therapy, and antioxidant therapy.
