SEASONAL CHEMICAL EVOLUTION OF THE ALGA CYSTOSEIRA ELEGANS

Article abstract of DOI:10.1016/0031-9422(81)84064-2

Among the Mediterranean algae belonging to the family Cystoseiraceae analysed for diterpenic compounds, only Cystoseira elegans contains eleganolone, epoxy-eleganolone and elegandiol, as does the Atlantic alga Bifurcaria bifurcata.Surprisingly, for the seasonal Cystoseira elegans, these compounds are present only at the beginning of growth of the alga during Spring and they disappear in the Summer yielding important seasonal variation data for diterpenoids, and also for sterols, alginic acid, mannitol and cellulose.Key Word Index - Cystoseira elegans; Cystoseiraceae; Phaeophyceae; eleganolone; acyclic diterpenoids.
