Abstract
Continuing an investigation of the alkaloids of the epigeal part of Petil~um ed~d~ (Rgl.) Vved [i, 2], the mixture of bases from the pH 8 fraction was chromatographed on a column of silica gel. A benzene--methanol (9:1) eluate yielded the new alkaloid ed~etisidine with mp 257-259°C (acetone), [a] D-33.63 ° (c 1.87; methanol). C=TH~sNOs (I), M"429, IR spectrum of (I), lmax, cm-*: 3400 (OH), 2760 (trans-quinolizidine), 1670 (>C---C<).
