Abstract: The methanol extract of an assemblage of Halimeda stuposa and a Dictyota sp., yielded three natural products characteristic of Dictyota sp., and one of Halimeda sp. These included the xenicane diterpene 4-hydroxydictyolactone (1), and the diterpenes dictyol E (2), 8a,11-dihydroxypachydictyol A (3) and indole-3-carboxaldehyde (4). A minor revision of 1 and new spectroscopic data for 1 and 2 are provided, along with associated anti-cancer activities of compounds 1–4.
Keywords: Dictyota; Dictyotaceae; Halimeda stuposa; anti-cancer activity; xenicanes; diterpenes; 4-hydroxydictyolactone; dictyol E; 8a,11-dihydroxypachydictyol A; indole-3-carboxaldehyde
