Two new acetylenic glucosides, 4′,6′-acetonide-8Z-decaene-4,6-diyne-1-O-β-D-glucopyranoside named carthamoside A1 (1) and 4,6-decadiyne-1-O-β-D-glucopyranoside named carthamoside A2 (2), along with one known acetylenic glucoside, 8Z-decaene-4,6-diyne-1-O-β-D-glucopyranoside (3), have been isolated from the air-dried flower of Carthamus tinctorius, these structures have been identified on the basis of spectroscopic methods.

In the search for novel and bioactive molecules for drug discovery, marine-derived natural resources, especially marine microorganisms are becoming an important and interesting research area. This study covers the literature published after 2008 on secondary metabolites of marine-derived microorganisms. The emphasis was on new compounds with the relevant biological activities, strain information, and country of origin. New compounds without biological activity were not included.
