Flavonol Glycosides From Reseda Lutea L
(Elsevier Ltd., 2019) Kızıltaş, Hatice; Küçüksolak, Melis; Duman, Seda; Bedir, Erdal
Two new flavonol glycosides; kaempferol-3-O-[2-O-(beta-D-xylopyranosyl)-3-O-(beta-D-glucopyranosyl)]-alpha-L-rhamnopyranosyl-7-O-alpha-L-rhamnopyranoside (1) and kaempferol-3-O-[2-O-((6-O-trans-p-coumaryl)-beta-D-glucopyranosyl)-3-O-(beta-D-xylopyranosyl)]-alpha-L-rhamnopyranosyl-7-O-alpha-L-rhamnopyranoside (2) were isolated from the aerial parts of Reseda lutea L., together with five known flavonol glycosides. Structural elucidation of the compounds was based on both spectroscopic evidence and reference data comparison. The new compounds are the first tetrasaccharidic secondary metabolites isolated from Resedaceae family.

Biotransformation of Cyclocanthogenol by the Endophytic Fungus Alternaria Eureka 1e1bl1
(Elsevier Ltd., 2018) Ekiz, Güner; Duman, Seda; Bedir, Erdal
The microbial transformation of cyclocanthogenol (CCG), Astragalus sp. originated sapogenin, by the endophytic fungus Alternaria eureka 1E1BL1 isolated from Astragalus angustifolius was investigated. Hydroxylation, oxidation, epoxidation, O-methylation, ring-expansion and methyl migration reactions were observed on the triterpenoid skeleton. As a result, eight metabolites were isolated and the structures of the previously undescribed compounds were established by 1-D, 2-D NMR and HR-MS analyses.
