Chemical constituents from the roots of Senecio scandens

Abstract

The chemical constituents of the roots of Senecio scandens Buch.-Ham. grown in the Funiu mountains in China have been investigated. Four compounds were isolated and identified as β−sitosterol (1), pentacosanoic acid (2), 19α-H lupeone (3), and sucrose (4). The structures of these compounds were elucidated on the basis of chemical and spectroscopic evidence. 19α-H Lupeone (3) was isolated as a single compound and its structure established unambiguously by the spectral method for the first time, and 1H and 13C NMR data were assigned wholly by 1D and 2D NMR.
