Secondary Metabolites from Rubiaceae Species

Secondary metabolites from Rubiaceae species.

This study describes some characteristics of the Rubiaceae family pertaining to the occurrence and distribution of secondary metabolites in the main genera of this family. It reports the review of phytochemical studies addressing all species of Rubiaceae, published between 1990 and 2014. Iridoids, anthraquinones, triterpenes, indole alkaloids as well as other varying alkaloid subclasses, have s...

Bioactive secondary metabolites from Juncaceae species

Identification of some secondary metabolites produced by four Penicillium species

Fungi produce a wide range of secondary metabolites such as antibiotics, toxins, alkaloids, fatty acids, ketones and alcohols during active cell growth. The present study was aimed to identify secondary metabolites from some Penicillium species, using GC-MS. Many important compounds such as 3-oxoquinuclidine in Penicillium jenseii, formamidine in Penicillium pusillum, orcinol and 1,3,8-p-mentha...

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...
