In the course of our phytochemical study on Mediterranean and Atlantic brown algae (Culioli et al., 2004, and references cited herein; [El Hattab et al., 2006], [El Hattab et al., 2008a], [El Hattab et al., 2008b], [Ortalo-Magné et al., 2005], [Valls and Piovetti, 1995] and [Valls et al., 1995]), we have now re-investigated the lipid extract of Zonaria tournefortii (J.V. Lamouroux) Montagne collected off the Algerian Mediterranean coasts at Tipaza (La Corne d'Or) in May 2001. The object of this investigation was to complete our previous study on the phloroglucinol derivatives of this species (El Hattab et al., 2006 M. El Hattab, L. Piovetti and C.E. Chitour, J. Soc. Alger. Chim. 16 (2006), p. 69.El Hattab et al., 2006) and, as far as possible, to suggest a plausible biosynthetic pathway for these compounds.
