Abstract
The essential oils from the leaves, fruits, roots, and stems of Solanum xanthocarpum, growing wild in Nepal, have been obtained and analyzed by gas chromatography-mass spectrometry. The fruit volatiles were dominated by benzyl benzoate (21.7%) and (E,E)-geranyl linalool (12.6%); heptacosane (20.0%) was the major component of the leaf oil; the stem oil was dominated by palmitic acid (28.9%), heptacosane (12.8%) and linoleic acid (10.1%); while solavetivone (22.9%), palmitic acid (21.0%), and linoleic acid (8.2%) were the major components of the root essential oil. There do not seem to be any common phytochemical taxonomic markers in the essential oils of Solanum spp; the chemical diversity observed in this genus mirrors the taxonomic diversity.
