Abstract

Background and objectives: Melasma is one of the most common pigmentary disorders. It has a considerable impact on quality of life. The treatment of melasma has still remained a challenge because the efficient treatment has not been proven until now and there is still a need to find new depigmenting products.Allium cepa L. and Cucumis melo L. seeds as well as tragacanth have been introduced in Iranian traditional medicine (ITM) as depigmenting agents. Moreover, modern studies have shown their antioxidant and inhibitory mushroom tyrosinase effect.In this study, a topical gel containing Allium cepa L. and Cucumis melo L. seeds extract was prepared with tragacanth and quality control evaluations have been accomplished. Method: After performing quality control of plants seeds and tragacanth according to pharmacopoeia, the ethanol extract of A. cepa and hydroalcoholic extract of C. melo seeds were prepared. An appropriate gel formulation was selected on the base of suitable viscosity. The gel product was formulated using 5% of each plant extracts in tragacanth gel base. In addition, the herbal gel was evaluated using pharmaceutical behavior such as physical appearance, pH, viscosity, spreadability as well as phenolics content. Results: The herbal gel product showed acceptable pharmaceutical behavior as well as considerable phenolic content (1.43±0.01 mg/g). Conclusion: The prepared topical gel product could be a good natural formulation candidate for clinical studies in the field of hyperpigmentation. Moreover, phenolic content of the product could be considered as an indicator for its quality control.
