Chemical analysis of some plants used for cosmetic purposes in Turkish ethnobotanical studies and their in vitro physiological effects on human origin cell lines

Türkiye has long been known for its wealth of natural medicinal and cosmetic resources. In terms of plant diversity, Türkiye is one of the wealthiest countries on Earth. Thirty percent of the 10,500 plant species identified in Türkiye to date are endemic. This richness translates into a high use of plants for medicinal or cosmetic purposes. As a result of ethnobotanical research conducted in Türkiye, several plant genera widely used by local people for cosmetic purposes have been identified. This study aims to rationalize the traditional cosmetic uses of plants in Türkiye by conducting ethnobotanical studies across different provinces, collecting plants, screening for biological activities, assessing cytotoxic effects on skin cell lines, and conducting in-depth phytochemical analysis of the most promising plants. This is to develop new cosmetic formulations using local plants.
