A chromanone alkaloid from Derris ovalifolia stem.


PMID 19851932

Abstract

From the stem of Derris ovalifolia, a new chromanone alkaloid characterised as 7-methoxy-3-[1-(3-pyridyl)methylidene]-4-chromanone (1) was isolated along with four known compounds, dehydrotoxicarol (2), dehydrodeguelin (3), toxicarol isoflavone (4) and indole-3-carbaldehyde (5). Their structures were determined on the basis of spectral data interpretation. The structure of compound 1 has also been confirmed by synthesis.
