Antioxidant Activity of Geum Rivale
نویسندگان
چکیده
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 roots of G. rivale with high total phenolic content of 17.48% was proven to be about twice as effective as the other extracts tested. Ethyl acetate and n-butanol were demonstrated to be the best solvents for optimal concentration of antioxidant con-

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 کاملRare Ellagic Acid Sulphate Derivatives from the Rhizome of Geum rivale L.—Structure, Cytotoxicity, and Validated HPLC-PDA Assay
Two rare sulphate ellagic acid derivatives were isolated from the rhizome of Geum rivale L. in three simple steps. Their structures were identified by comprehensive NMR studies (1H NMR, 13C NMR, 1H-1H COSY, HMBC, HSQC) as 3,3′-dimethoxy-4-sulphoxyellagic acid potassium salt (1) and 3,3′,4′-trimethoxy-4-sulphoxyellagic acid potassium salt (2). Subsequently, a new precise (RSD < 2.6%), accurate (...

متن کاملPollen Tube Transmitting Tissue: Place of Competition of Male Gametophytes
In angiosperm reproduction, pollen tubes elongate from the stigma through the stylar transmitting tissue to the ovary to deliver the male gametes for fertilization. This article reviews different forms of pollen tube transmitting tracts within the style as well as possibilities for bridging the gap from the transmitting tissue to the ovule. The pollen tube transmitting tissue is the place of po...
