The researchers whose trusted networks rank it highest, strongest advocate first. Every researcher gets a different order.

Edible films and coatings based on mango (var. Ataulfo) by-products to improve gas transfer rate of peach (2018, methodology): “The reduction of DPPH radical was made following the methodology reported by Molyneux (2004) with some modifications.”
An Assessment of the Antioxidant and Antimicrobial Activity of Six Species of Edible Irish Seaweeds (2010, background): “DPPH results are often interpreted as the “efficient concentration” or EC50 value, which is defined as the concentration of substrate that causes 50% loss of the DPPH activity (Molyneux, 2004).”
Genesis and development of DPPH method of antioxidant assay (2011, methodology): “1, the overall stoichiometry need not necessarily be a whole integer (Molyneux 2004).”
Antioxidant activity of some seaweed from the gulf of Thailand (2011, methodology): “conoides, could eliminate the free radicals by acted as free radical scavengers (Molyneux, 2004) or by donating a hydrogen atom to the molecule (Re et al.”
Estimation of antiradical properties of antioxidants using DPPH assay: A critical review and results (2012, background): “A detailed literature survey revealed that most of the studies are based on fixed reaction time ranging from 20–30 min instead of total reaction time that is actually required to attain steady state to complete this redox reaction (Molyneux, 2004).”
