Investigation into biologically active constituents of Geum rivale L.
Aerial and underground parts of Geum rivale (Rosaceae) were investigated. Tiliroside, gallic acid, ellagic acid and a sterol fraction were isolated from aerial parts of the plant. The sterol fraction was analyzed using GC-MS. Eleven phenolic acids were identified in aerial parts of the plant, and eight in underground parts, by means of RP-HPLC analysis. The quantitative determination of phenoli...
متن کاملAntioxidant Activity of Geum Rivale
Two species of the Rosaceae genus Geum, comprising high amounts of tannins and phenolic acids, were investigated in terms of their antioxidant activity. Antioxidant potential of different extracts from aerial and underground parts of Geum rivale and G. urbanum was studied using various in vitro methods (FC, DPPH, FRAP and linoleic acid peroxidation test). The hydromethanolic extract from the ro...
متن کاملAntimicrobial and antioxidant potential of different solvent extracts of the medicinal plant Geum urbanum L.
Many Geum species are known to be rich in biologically active compounds and therefore could be a source of new natural products with pharmacological potential. The medicinal plant Geum urbanum L. is widespread in Bulgaria and has been used in folk medicine. In the present study, the methanol extracts of the roots and aerial parts of G. urbanum and their fractions (petroleum ether, ethyl acetate...
متن کاملFatty acid synthase inhibitors from Geum japonicum Thunb. var. chinense.
Bioassay-guided fractionation of the MeOH extract of Geum japonicum Thunb. var. chinense using the fatty acid synthase inhibition assay led to the isolation of a new dimeric ellagitannin, gemin G (1), together with six known compounds, gemin A (2), casuarinin (3), pedunculagin (4), potentillin (5) , tellimagrandin II (6), and ellagic acid (7). Their structures were determined on the basis of sp...
متن کاملQuantification of sucrose in the root of Geum iranicum Khatamsaz
Geum iranicum Khatamsaz (Rosaceae) is an endemic plant in Iran. The infusion and decoction of the plant have been used by local people for medicinal purposes. Our previous work on phytochemical studies on G. iranicum showed that the root was rich in sugars and sucrose was identified as a major one in it. In this study, the content of sucrose in the hydro-alcoholic (1:1) extract of the root of G...
