Diterpenes From the Marine Brown Algae of the Genus Dilophus

“…Up to the present time, 9 spatane diterpenes have been found in D. marginatus or D. okamurai ( Figure 3; Table 2). Five spatane compounds (20)(21)(22)(23)(24) are isolated from the brown alga D. marginatus collected from Collaroy, New South Wales, Australia. 8 Compounds 21 and 22 are also isolated from the brown alga D. okamurai collected on the coast of Kamaishi, Iwate Prefecture, Japan.…”

High pressure extraction of bioactive diterpenes from the macroalgae Bifurcaria bifurcata: an efficient and environmentally friendly approach

“…1 Bifurcaria bifurcata is a brown macroalga that thrives, year-round, in the intertidal areas (the lower shore, rockpools and mid-shore) along the coast of the Northern Atlantic, from Morocco (southern limit) to north-western Ireland (northern limit). [2][3][4] The chemical composition of this brown macroalga has gained particular attention, due to the abundance of a variety of acyclic diterpenes. [5][6][7][8][9][10][11][12] Compared to their cyclic counterparts, these linear diterpenes are relatively quite rare in nature, 2 yet quite interesting since a vast range of promising bioactivities have been recognized for them.…”

“…[5][6][7][8][9][10][11][12] Compared to their cyclic counterparts, these linear diterpenes are relatively quite rare in nature, 2 yet quite interesting since a vast range of promising bioactivities have been recognized for them. 2,3,7,8,[13][14][15] Recently, Santos et al 5 demonstrated the antioxidant, anti-inammatory and antibacterial activities of B. bifurcata lipophilic extracts, mainly composed of linear diterpenes. In addition, a promising synergism was observed when these extracts were used together with antibiotic families of major clinical importance.…”

Bifurcaria bifurcata: a key macro‐alga as a source of bioactive compounds and functional ingredients

“…The genus Bifurcaria belonging to Sargassaceae family comprises two known species: the Bifurcaria bifurcata (Velley) R. Ross and B. galapegensis (Piccone & Grunow) Womersley. Among this family, B. bifurcata is a specie that lives in rock pools on the lower and middle tidal zones and at the upper limit of the subtidal shore, distributed from Morocco (southern limit) to north-western Ireland (northern limit) (Le Lann et al, 2008Muñoz et al, 2013). This species has revealed a rich array of acyclic diterpenoids, some of them being quite rare in nature.…”
