Chemical Constituents from the Colombian Medicinal Plant Niphogeton ternata

Abstract

Two coumarins and one polyacetylene, 5-O-(3-chloro-2-hydroxy-3-methylbutyl)-8-methoxypsoralen (1), 2′, 3′-dihydro-jatamansin (2), and 10-chloro-1-heptadecene-4, 6-diyne-3, 8, 9-triol (3), along with 15 known compounds (4—18), were isolated from the methanol extract of Niphogeton ternata. Their structures were elucidated by spectroscopy.
