Flaxseed lignan wound healing formulation: Characterization and in vivo therapeutic evaluation.

Key Findings:

The topical administration of a lignan enriched flaxseed extract cream was assessed in Wistar rats with open wounds. Flaxseed extract provided antioxidant and healing properties, which were attributed to polyphenol and phenolic compounds. Positive effects were noted on fibrous tissue formation and collagen migration by in vivo histological examination.

ABSTRACT:

Flaxseed lignans are a natural source of useful biologically active components that show a diverse spectrum of health promoting properties. The valuable effects of the phenolic molecules are mainly due to their antioxidant activity by preventing oxidative stress and stimulate collagen synthesis, therefore, providing benefits to the skin. The present work highlights the development of flaxseed extract formulation as novel wound healing agent. The recognition of key structural features within flaxseed extract was crucial for the design and development of the therapeutic cream. Chromatographic analyses were employed for bioactive compounds identification and quantification. Folin–Ciocalteu method determined the total phenolic content and the antioxidant properties were evaluated by DPPH assay. The storage and loss modulus and tan ı were calculated for cream rheological properties evaluation. In vitro diffusion capacity and in vivo wound healing activity of phenolic cream were evaluated on Wistar rats. The collective properties and healing effect of the flaxseed suggested wound healing capacity. (Author’s abstract)
