Abstract
Two new lactones, γ-butyrolactone and δ-valerolactone were isolated from the methanolic extract of Solanum nigrum. Structure elucidation was carried out by exhaustive 2D NMR analysis. The structures of the lactones depict the outcome of their isolation as a situation that involve the formation of artifacts.
