Investigation of Antioxidant Activity and Fatty Acid Contents of Solanum dulcamara

The fatty acid compositions of the leaves and fruit of Solanum dulcamara were determined by gas chromatography. The leaf oil of S. dulcamara is remarkably rich in linolenic acid. Among the S. dulcamara extracts, according to the 2,2-diphenyl-2-picrylhydrazyl method, hexane and methanol show the highest activity levels in fruit and leaves, respectively. According to the β-carotene-linoleic acid method, dichloromethane has the highest activity level in both fruit and leaf. However, according to the modified cupric-reducing antioxidant capacity method, ethyl acetate and dichloromethane have the highest activity levels in fruit and leaves, respectively. The antioxidant activity levels and fatty acid contents of S. dulcamara are presented for the first time in this study.
