Abstract
Three minor alkaloids, lythrancine-V,-VI, and -VII have been isolated from Lythrum anceps Makino. Lythrancine-V is the C-3 epimer of lythrancine-IV. Lythrancine-VI and -VII are the deacetyl derivatives of lythrancine-V. Mass spectral data and a chemical conversion of lythrancine-III into lythrancine-V give their structure and absolute configuration. Lythrancine-V, -VI, and -VII are represented as (II), (VIII), and (IX), respectively.Keywords
