Phytochemical Diversity of Eremostachys laciniata Bunge Populations in Iran

Secondary metabolites from the roots of Astragalus maximus

Background and objectives: Astragalus is one of the most abundant genera of flowering plants in Iran. There are a few reports on phytochemical investigation of this valuable genus. Saponins, flavonoids and polysaccharides have been reported as the most important metabolites in Astragalus species. In the present research, we aimed to identify the foremost const...

Secondary metabolites from marine microorganisms.

After 40 years of intensive research, chemistry of marine natural products has become a mature field. Since 1995, there are signals of decreased interest in the search of new metabolites from traditional sources such as macroalgae and octocorals, and the number of annual reports on marine sponges stabilized. On the contrary, metabolites from microorganisms is a rapidly growing field, due, at le...

Secondary Metabolites from Polar Organisms

Polar organisms have been found to develop unique defences against the extreme environment environment, leading to the biosynthesis of novel molecules with diverse bioactivities. This review covers the 219 novel natural products described since 2001, from the Arctic and the Antarctic microoganisms, lichen, moss and marine faunas. The structures of the new compounds and details of the source org...
