title: Trianthenol: an antifungal tetraterpenoid from Trianthema portulacastrum (Aizoaceae).
abstract: An antifungal tetraterpenoid named trianthenol 1 has been isolated from the chloroform extract of Trianthema portulacastrum. Its structure was established as 15-hydroxymethyl-2,6,10,18,22,26,30-heptamethyl-14-methylene- 17-hentriacontene on the basis of spectroscopic data including high resolution mass and two-dimensional NMR techniques. A benzaldehyde derivative 2, a pentacyclic triterpenoid 3 and benzoic acid derivatives 4-5 are also reported for the first time from Trianthema portulacastrum.
