Within a project focusing on the chemopreventive potential of algal phenols, two phloroglucinol derivatives, belonging to the class of fucophlorethols, and the known fucotriphlorethol A were obtained from the ethanolic extract of the brown alga Fucus

Thalli of the brown alga Ascophyllum nodosum were collected on the Scottish west coast and the phlorotannin content was measured once a month between January and December 2005. Due to the potential use of A. nodosum extract as a nutritional supplemen

1. The degradation of tryptophan (Try) and some of its potential intermediates has been studied in Endomycopsis vernalis. The following degradation products were identified in surface-cultures of Endomycopsis which had been fed with C-14-labeled D,L-

The structural elucidation of four phloroglucinol derivatives isolated from the ethanolic extract of the brown alga Carpophyllum angustifolium after peracetylation is described. Three of them, trihydroxyheptaphlorethol-A octadecaacetate, trihydroxyoc

From an ethyl acetate fraction of the brown alga Cystophora retroflexa several halogenated phlorotannins were isolated. Most of the compounds are derivatives of diphlorethol penta-acetate and triphlorethol-A hepta-acetate. The majority turned out to

The ethanolic extract of the brown alga Cystophora retroflexa has yielded three different classes of phlorotannins. Most substances belong to the classes of phlorethols and fucophlorethols. Only one, well known fucol, the difucol hexa-acetate, was is

The GC-MS study of the head space volatiles of Citrus taitensis Risso revealed that the main component, constituting 60% of the oil, is linalool. Three N-containing compounds, benzyl cyanide, indole and methyl anthranilate, constituted a considerable

In addition to a large number of fuhalols and phlorethols previously identified in an ethanolic extract of Sargassum spinuligerum, a new class of fuhalols was isolated in form of their peracetyl derivatives and identified by means of spectral analysi

The brown alga Sargassum spinuligerum contains a variety of fuhalols. In addition to these compounds, a number of fucophlorethols were isolated in the form of their peracetylated derivatives and identified by means of spectral analysis. The following

A number of phlorotannins were isolated at their peracetyl derivatives and identified by means of spectral analysis. The new compounds belong to the class of hydroxylated branched fucophlorethols and bisfucophlorethols lacking a 1,2,3-triphenoxy-5-ac
