Acetogenins from the aquatic plant Elodea canadensis

13-(2-furyl)-Tridec-12E-en-1-yne and (7S)-hydroxyhexadeca-8E,10Z,13Z-trienoic acid have been isolated from Elodea canadensis in addition to the already known 13-(2-furyl)-tridec-1-yne, hexadec-11Z-enoic, hexadeca-7Z,10Z,13Z-trienoic and (10R)-hydroxyhexadeca-7Z,11E,13Z-trienoic acids. © 1985

Cycloartane triterpenes from Juncus effusus

A new triterpene, cycloart-23Z-enfe-3β,25-diol and other oxygenated cycloartanes have been isolated from Juncus effusus. The configurations at C-24 of the epimeric 24,25-epoxycycloartan-3β-ols, cycloart-25-ene-3β,24-diols and cycloartane-3β,24,25-triols have been attributed on the basis of chemical correlations. The 1H and 13C NMR chemical shifts of the 24R- and 24S-stereomers are also reported. © 1994
