Black currants (Ribes nigrum) and red currants (Ribes rubrum) are highly appreciated for the food and therapeutic value of their fruits. Mineral composition was determined in eight black currants cultivars (‘Record’, ‘Bogatar’, ‘Deea’, ‘Abanos’, ‘Blackdown’, ‘Ronix’, ‘Tinker’, ‘Tenah’) and three red currants cultivars (‘Rosu timpuriu’, ‘Abundent’, ‘Houghton Castle’). For both species analyzed, ...

We developed a new approach using RAPD fingerprints to distinguish 37 currant cultivars from northeastern China based on optimization of RAPD by choosing 11 nucleotide primers and strict screening PCR annealing temperature. We found that the manual cultivar identification diagram (MCID) approach clearly developed fingerprints from 8 different primers that were useful for cultivar identification...

Antimicrobial activity of Ribes nigrum L. and rubrum leaf extracts was determined by disk-diffusion method as well specific growth rate generation succeeding factor determination. Different Gram-positive (Bacillus subtilis WT-A, Staphylococcus aureus MDC 5233, Enterococcus hirae ATCC 9790) Gram-negative (Escherichia coli 25922, Salmonella typhimurium MDC1754, ampicillin resistant E. dhpα-pUC18 ...

Alaska’s domesticated and native Ribes and Rubus genera have virtually gone unchecked for pathogen detections. Cultivated Ribes species are predominantly found in home gardens and landscape areas along highways and in cities. In 2008, while surveying native plants for diseases in North Central Alaska near the town of North Pole, mottled leaves were readily visible on wild raspberries (Rubus str...

Fruits from 107 genotypes of Vaccinium L., Rubus L., and Ribes L., were analyzed for total anthocyanins (ACY), total phenolics (TPH), and antioxidant capacities as determined by oxygen radical absorbing capacity (ORAC) and ferric reducing antioxidant power (FRAP). Fruit size was highly correlated (r = 0.84) with ACY within Vaccinium corymbosum L., but was not correlated to ACY across eight othe...

For over a century, white pine blister rust (Cronartium ribicola) has linked white pines (Strobus) with currants and gooseberries (Ribes) in a complex and serious disease epidemic in Asia, Europe, and North America. Because of ongoing changes in climate, societal demands for forests and their amenities, and scientific advances in genetics and proteomics, our current understanding and management...

BACKGROUND The blackcurrant (Ribes nigrum L.) is a species of native currant which contains a lot of polyphenolic antioxidants which is used medicinally and has a fundamental role in the maintenance health. MATERIALS, METHODS AND OBJECTIVE: Ultraviolet-visible spectrophotometry and ultraviolet range high performance liquid chromatography (HPLC) were used to characterize the polyphenolic content...
