Fucoxanthin and Its Metabolites in Edible Brown Algae Cultivated in Deep Seawater
Kanami Mori,Takashi Ooi,Masanori Hiraoka,Naohiro Oka,Hideyuki Hamada,Mitsumasa Tamura,Takenori Kusumi +6 more
TL;DR: Three metabolites of fucoxanthin were isolated from a brown alga, Scytosiphon lomentaria, and the structure of a new compound was determined by NMR, revealing a biologically active carotenoid in brown algae.

Structure Revision of Aspergillides A and B, Cytotoxic 14-Membered Macrolides from Aspergillus ostianus, by X-ray Crystallography
TL;DR: In this paper, the structure of aspergillides A and B was revised as 1 and 3, respectively, for X-ray crystallography, resulting in the revision of the structures of both compounds.
Journal ArticleDOI
New terpenoid components from the volatile oils of the soft corals Clavularia viridis and Sarcophyton acutangulum.
TL;DR: A new tetracyclic terpenoid hydrocarbon, cyclosinularane, and (+)-alloaromadendrene, the enantiomer of terrestrial (-)-alloarsedrene, have been isolated from the volatile oil of the soft corals Clavularia viridis and Sarcophyton acutangulum, respectively.
