Lawsonia inermis flowers were evaluated for chemical and biological properties for the first time. Extracts were prepared successively by hexane, chloroform and methanol. Phenolics (7.8-239.0g gallic acid equivalent/kg of dry mass), tannins (12.5148.5mg cathechin equivalent/kg of dry mass) and flavonoids (36.2-43.75mg quercetin equivalent/kg of dry mass) were quantified. Methanol extract has a ...
