Applications of the biological properties of Nymphaea rubra flower and leaf extracts in developing nanoemulgel-based product

The present study investigated the biological properties of Nymphaea rubra Roxb. ex Andrews (N. rubra) for their potential as natural active ingredients in nanoemulgel formulation. Water, ethanolic, and methanolic extracts were evaluated for total phenolic content (TPC) and demonstrated antioxidant activities, including their ability to scavenge 2,2-diphenyl-1-picrylhydrazyl (DPPH), 2,2 ′ -azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS), and nitric oxide (NO) radicals in vitro, as well
