BIFURCARIA BIFURCATA PDF

Marine resources are considered as a very promising source of bioactive molecules, and macroalgae in particular have gained special attention, due to their structurally diverse composition. Particular interest has been devoted to the brown macroalga Bifurcaria bifurcata , due to their abundance in bioactive linear diterpenes. In this appraisal, a thorough review concerning the methodologies used in the extraction, fractionation, and identification of diterpenes from B. An exhaustive compilation of the mass spectra and nuclear magnetic resonance NMR data are also provided. The in vitro and in chemico assays already performed to assess different biological activities attributed to B. The associated major strengths and challenges for the exploitation of B.

Bifurcaria bifurcata in shallow water. Clump of Bifurcaria bifurcata. Ross, Authority R. Summary Description Up to 50 cm in length. Olive-yellow in colour, but much darker when dry. Holdfast expanded and knobbly. Frond cylindrical, unbranched near base then branching dichotomously.

Elongate reproductive bodies present at ends of branches. Rounded air bladders sometimes present. Recorded distribution in Britain and Ireland Bifurcaria bifurcata is a southern species found on the Atlantic coast of France, Spain and Portugal and extending to the south and west coasts of England and the west coast of Ireland where it is sometimes common.

It is absent from Scotland. Global distribution -. Habitat Bifurcaria bifurcata is usually found in rock pools on the middle and lower shore, particularly on exposed beaches. It also forms a low water zone in some locations in south-west England and west Ireland. Depth range -. Identifying features Sterile tips to fronds are rounded and slightly enlarged.

Air bladders, if present, are small. Unlike the other fucoids, Bifurcaria bifurcata has no disc-like holdfast. Additional information Bifurcaria bifurcata is perennial and hermaphroditic.

Trihydroxylated Linear Diterpenes From the Brown Alga Bifurcaria Bifurcata

Two novel polar diterpenes were isolated from the brown alga Bifurcaria bifurcata collected off the Atlantic coast of Morocco, and their structures established by spectral methods. Both compounds are trihydroxylated acyclic diterpenes derived from hydroxygeranylgeraniol. Their absolute configuration at the C position has been determined with a modified Mosher's method [J.
