Methods of extracting 1-4 cycle heterocyclic compounds and 2-5 cycle polynuclear aromatic hydrocarbons from a hydrocarbon feedstock are described. The methods include providing a hydrocarbon feedstock containing crude oil fractions, and determining an A/R ratio and an asphaltene concentration of the hydrocarbon feedstock. Based upon the A/R ratio and the asphaltene concentration, the treatable hydrocarbon feedstock undergoes one or more of cracking and fractionating. Subsequently, at least one targeted portion of the heterocyclic compounds is extracted from the fractionated stream with an aqueous solvent. A stream containing the 2-5 cycle polynuclear aromatic hydrocarbons is transferred to an extractor and the 2-5 cycle polynuclear aromatic hydrocarbons are extracted with a solvent system comprising an aprotic solvent.
