Abstract
Plant-derived compounds with antioxidant activity are regarded as contributors to optimum health in humans.
Small fruits including species of currants, gooseberries, raspberries and blackberries are known to contain high levels of antioxidant activity.
A multi-year survey is being conducted to quantify and compare the levels of antioxidant activity in the currant (Ribes nigrum), gooseberry (Ribes grossularia), raspberry and blackberry (Rubus spp.) accessions held in the Canadian Clonal Genebank collection.
The ferric reducing antioxidant power (FRAP) method was used to quantify total antioxidant power in fruit samples collected from the field.
The FRAP assay was standardized against plant flavonoids and ascorbic acid.
In data obtained in the first year of the study, black currant accessions demonstrated the highest antioxidant activities followed by raspberries and gooseberries.
Some wild Rubus species exhibited activities significantly higher than the cultivars.
This study will be continued over three years and effects of season will be evaluated.
