Total phenolic content and primary antioxidant activity of methanolic and ethanolic extracts of aromatic plants’ leaves

The aim of this study is to determine the total phenolic content and primary antioxidant activity of methanolic and ethanolic extracts of four aromatic plants’ leaves namely knotweed (Polygonum minus), curry (Murraya koenigii), kaffir lime (Citrus hysrix) and fragrant screwpine (Pandanus oduru...
