The calculated values, net charges, MESP contours/surfaces have also been drawn to explain the electronic reactivity of Quercetin, bond lengths, dipole moments, heats of formation, QSAR properties, Lipinski’s parameters, Ligand efficiency (LE), Lipophilic Efficiency (LipE), are reported and discussed, to understand the biological activity of the Quercetin Derivatives.enQuercetin, Anti-Malaria activity, SAR, drug-like, Lipinski rule, HF, DFT,Article
