Extraction and determination of the total phenolic content from different parts (leaves and stems) of spinacia oleracea by using water and ethanol / Noorafiza Fauzi

This study was carried out to determine the total phenolic content in spinach by using water and ethanol as the solvent for extraction. This study also compared the total phenolic content of the spinach leaves and stems. The total phenolic content was determined by using folin-ciocalteu reagent with...
