Evaluation of bioactivities of ultrasound-assisted extraction of betel leaves (Piper betle L.)

Abstract

In this study, the betel leaf extracts were obtained by using an ultrasound-assisted extraction method with different solvents (70% ethanol, 96% ethanol, and water). The biological compounds of the extracts were examined using different biochemical assays, namely total phenolic content, total flavonoid content. ABTS⁺ radical cation decolorization was using to determine the antioxidant activity. The antibacterial activity of the betel leaf extracts was determined using the agar diffusion and co-culture method...
