The fact that many health problems arise due to the use of synthetic ingredients has directed research to investigate the importance of natural products. Many fruits and vegetables are of nutritional value and considered as health promoters, due to the presence of various phytochemicals. It is known that Dahlia x hybrida contain secondary metabolites, including antioxidants that are important to human health. However, very little is known about nutritional and medicinal value of their leaves. In the present study, we have investigated the medicinal value of Dahlia x hybrida species. Antioxidant properties of the leaves were examined in the laboratory using different methanolic solvents by Soxhlet extractor. The total phenolic content of the extract was determined by Folin–Ciocalteu method. The dried fractions were screened for their antioxidant activity potential by 1diphenyl 2 picryl hydrazyl (DPPH), ferric reducing power (FRAP). The results showed that waste extract obtained from Dahlia x hybrida species exhibited remarkable antioxidant activity. Our conclusion, of the present study is that Dahlia x hybrida is possibly a vegetable bye product that has immense potential as sources of polyphenols. However, more research should be carried out to identify other possible antioxidants and bioactive compounds in these resources.
