Sumnary: Optically active carnosadine , a new cyclopropyl amino acid from red alga Gratebupia oarnosa, was synthesized and its absolute structure was determined. In a previous paper, we reported an isolation of a new amino acid carnosadine (l), lamino-Z-guanidinomethylcyclopropane-1-carboxylic acid,

Two new cyclopropyl and lactone containing eicosanoids, constanolactone A and 8, were isolated as synthetic diacetate derivatives from the temperate red alga Constantinea simp7ex and their structures determined by spectroscopic means. A hydrolysis product of one of these helped to define the lactone
