Petroleum ether is mostly used by pharmaceutical companies and in the manufacturing process. It is a lightweight hydrocarbon used chiefly as a nonpolar solvent. The extract of aerial parts of ageratum conyzoids in petroleum ether plays an essential role for the isolation of sigmasterol and beta sitosterol. Crude petroleum spirit and methanol extracts also play an important role for the screening of antimicrobial activity of the stem bark, leaves and roots of ficus thoningii.
