    Development of Liposomal Formulations of the Eggplant Glycoalkaloids Solasonine and Solamargine
    (Elsevier, 2022) Tatlıdil, Engin; Gürbüz, Nergiz; Doğanlar, Sami; Frary, Anne
    The eggplant glycoalkaloids solasonine and solamargine are efficient biomacromolecules against skin diseases but are water-insoluble which results in inefficient treatment due to inadequate transdermal delivery. To address this problem, several liposomal formulations were prepared and evaluated for parameters including lecithin type, hydration temperature, and pH. The optimal formula with high physical and chemical stability included the lecithin Phospholipon 80H hydrated with 10 mM NaCl (pH 5.5). Solasonine - solamargine loaded liposomes were tested for their physical and chemical stability and drug leakage over a three-month period. Furthermore, the drug release profile of the loaded liposomes was evaluated with different release media. The glycoalkaloids and their liposomal formulations were assessed for their biological activity in culture using HaCaT and SCC-25 cell lines. This work resulted in a biologically effective liposomal formulation that was stable (size <220 nm, PDI [removed]80%) for at least three months.

    Health Benefits and Bioactive Compounds of Eggplant
    (Elsevier, 2018) Gürbüz, Nergiz; Uluışık, Selman; Frary, Anne; Frary, Amy; Doğanlar, Sami
    Eggplant is a vegetable crop that is grown around the world and can provide significant nutritive benefits thanks to its abundance of vitamins, phenolics and antioxidants. In addition, eggplant has potential pharmaceutical uses that are just now becoming recognized. As compared to other crops in the Solanaceae, few studies have investigated eggplant's metabolic profile. Metabolomics and metabolic profiling are important platforms for assessing the chemical composition of plants and breeders are increasingly concerned about the nutritional and health benefits of crops. In this review, the historical background and classification of eggplant are shortly explained; then the beneficial phytochemicals, antioxidant activity and health effects of eggplant are discussed in detail.
