A New Anthraquinone Isolated from Rumex Obtusifolius
In this research we studied Rumex obtusifolius (Polygonaceae) along with other plants used in traditional medicine in relation to the chemical reaction FBIT (Ferriprotoporphyrine Biocrystallization Inhibition Test) which may provide information on a possible action mechanism for presumed antimalarial plants. According to folk medicine Rumex obtusifolius has a pronounced detoxifying effect on th...
متن کاملStudies of the Amino Acid Sequence of Plastocyanin from Rumex obtusifolius (Broad-Leaved Dock)
Plastocyanins are low-molecular-weight cuproproteins, which occur in the chloroplasts of plants and algae. The exact biological function of the protein remains uncertain, but is probably associated with photosynthetic electron transport (Gregory, 1971). The small size and blue colour of the protein simplify the purification of plastocyanin, and studies with a number of species have been reporte...
متن کاملMechanical weeding of Rumex obtusifolius L. under different N, P and K availabilities in permanent grassland
In Europe, Rumex obtusifolius L. is the most problematic grassland weed species, especially under the conditions of organic farming. The aims of this study were (1) to investigate the effectiveness of repeated mechanical weeding of R. obtusifolius from the permanent sward, cut two or three times per year, by digging the plants out from 5 cm below the soil surface, and (2) to test the effect of ...

Functional Dyeing of Wool with Natural Dye Extracted from Berberis vulgaris Wood and Rumex Hymenosepolus Root as Biomordant
In this study, a functional colorant, Berberine, extracted from Berberis vulgaris wood was applied onto wool fiber using the extract of roots of Rumex Hymenosepolus as biomordant. The effect of treatment variables on the color strength of dyed fibers was examined. The fastness properties of dyed wool against washing, light, dry and wet rubbing were evaluated. Dyed samples were tested for an...
