Antioxidants and antibacterial properties of extracts from leaves and stem of pink flower Impatiens walleriana

Impatiens walleriana is a vibrant and flowering plant sources cherished for its antioxidants and antimicrobial properties. This research aimed to evaluate the impact of three different drying treatments (microwave drying, oven drying, and air drying) on the antioxidant compounds of leaves and stems...
