Polyacetylenverbindungen aus Jungia seleriana.
The aerial parts of JUNGIA SETERIANA afforded in addition to known compounds two pairs of isomeric C (17)-acetylenes which differ in the number of triple bonds and in the configuration of the 9,10-double bond. The structures and configurations followed from the UV and the (1)H-NMR spectra, especially from those of the corresponding ketones, which were obtained by manganese dioxide oxidation.
