activity of polyphenolic crude extracts as scavengers of superoxide radicals and inhibitors of xanthine oxidase.	in view of the pharmacological interest in phenolic substances, we have determined the total amount of anthocyanins and polyphenols present in the berries of several cultivars of ribes, rubus, and vaccinium genera. the in vitro antiradical activity of the crude extracts on chemically-generated superoxide radicals as well as the inhibitory activity towards the enzyme xanthine oxidase were studied. all the crude extracts examined showed a remarkably high activity towards chemically-generated super ...	1992	1332092
characterization of ribes rubrum callus cultured under low temperature.	ribes rubrum callus was cultured at the temperature of 15 degrees c for 28 d. the contents of proteins and lipids in the callus cultured at 15 degrees c in a 28 d culture was significantly increased, being 1.1- and 1.2-fold, respectively, of those in callus cultured at 25 degrees c. comparisons of the contents of monogalactosyldiacylglycerol (mgdg), digalactosyldiacylglycerol (dgdg), sulfoquinovosyldiacylglycerol (sqdg) and phosphatidyldiacylglycerol (pg) revealed that in the callus cultured at ...	1999	16232637
characterization of anthocyanins and proanthocyanidins in some cultivars of ribes, aronia, and sambucus and their antioxidant capacity.	anthocyanins and proanthocyanidins were characterized by hplc-esi-ms/ms coupled with a diode array and/or fluorescent detector in seven cultivars of ribes nigrum (black currant) and ribes rubrum (red currant, red lake), six cultivars of ribes grossularia (gooseberries), aronia melanocarpa(chokeberry), and sambucus nigra (elderberry). thirty-one different anthocyanins were detected in these berries, but not every anthocyanin was observed in each berry. a number of minor anthocyanins were identifi ...	2004	15612766
characterization of phenolic profiles of northern european berries by capillary electrophoresis and determination of their antioxidant activity.	berries are known to contain phenolic substances (i.e., flavonoids and phenolic acids), which comprise two large and heterogeneous groups of biologically active nonnutrients. this investigation evaluated the content and profile of the phenolic compounds present in six different berries found in northern europe. the latter included bilberry (vaccinium myrtillus), cowberry (vaccinium vitis-idaea), cranberry (vaccinium oxycoccus), strawberry (fragaria ananassa), black currant (ribes nigrum), and re ...	2005	16076138

effect of latitude and weather conditions on the regioisomer compositions of alpha- and gamma-linolenoyldilinoleoylglycerol in currant seed oils.	the regioisomer compositions of triacylglycerols (tag) 18:3(n-3)/18:2(n-6)/18:2(n-6) (ala/l/l) and 18:3(n-6)/18:2(n-6)/18:2(n-6) (gla/l/l) in seed oils of black and green currant ( ribes nigrum l.) and red and white currant ( ribes rubrum l.) varieties were determined by silver-ion high-performance liquid chromatography and mass spectrometry. the aim was to investigate whether latitude and weather conditions affect the regioisomer compositions of ala/l/l and gla/l/l and whether the regioisomeris ...	2009	19338273
biochemical properties of red currant varieties in relation to storage.	eleven red currant varieties (ribes rubrum l.) cultured in serbia were evaluated for some of their biochemical properties such as total phenolics, anthocyanins, ascorbic acid, invert sugar, soluble solid content, and acidity. the average amount of ascorbic acid varied from 50.5-71.6 mg/100 g fw, while concentration of invert sugars ranged from 6.0%-9.0%. the highest amounts of total phenolics and anthocyanins were detected in variety redpoll (153.4 mg gae/100 g fw and 19.3 mg/100 g, respectively ...	2010	21046468
separation, characterization and quantification of phenolic compounds in blueberries and red and black currants by hplc-dad-esi-msn.	the phenolic profile of four blueberry varieties (vaccinium corymbosum l., cv. toro, legacy, duke and bluecrop) and two varieties (rosenthal and rovada) of red currants (ribes rubrum l.) and black currants (ribes nigrum l.) cultivated in macedonia have been analyzed using hplc coupled to diode-array detection and tandem mass spectrometry with electrospray ionization. a complex profile of anthocyanins, flavonols, flavan-3-ols and hydroxycinnamic acid derivatives has been assayed in acetone-acetic ...	2011	21401099
