Pharmacophore characterization of chlorogenic acid and quercetin compound. (A) Chlorogenic acid (B) Quercetin. The sites that can form bonds are seen in circles. These atoms (sites) form bonds with the targeted compound. The green circles are the sites that represent the hydrophobic interactions, the yellow circles are the sites that represent the hydrogen acceptor, the red circle is the site that represents the negative ion force and the purple circle is the site that represents the aromatic force.
