Volatile components from the roots of Solanum pseudocapsicum.

The volatile components obtained by hydrodistillation of Solanum pseudocapsicum roots were analyzed by gas chromatography-mass spectrometry. A total of 41 compounds, representing 50% of the oil, were identified. The oil was found to contain fatty acids (26.8%), terpenoids (7.6%), and aldehydes (5.3%) as the major components. The dominant compounds were hexadecanoic acid (24.1%), 2-methoxy-3-isopropylpyrazine (2.8%), and 15-methylhexadecanoic acid (2.1%). Other notable components include beta-elemene and delta-elemene. The high proportion of fatty acids in this plant could contribute to its medicinal properties.
