anthocyanins in wild blueberries of quebec: extraction and identification.	anthocyanins were extracted from a mixture of berries of vaccinium angustifolium and vaccinium myrtilloïdes at 7.7 degrees c, 26 degrees c, and 79 degrees c using ethanol alone or ethanol acidified with hydrochloric, citric, tartaric, lactic, or phosphoric acids at a solvent to solid ratio of 10. the effect of these parameters on extracted anthocyanins stability was investigated. the ph-differential and hplc-dad methods were used to determine anthocyanin contents. extracted anthocyanins were pur ...	2007	17579428
measured elemental transfer factors for boreal hunter/gatherer scenarios: fish, game and berries.	the environmental assessment of long-term nuclear waste management requires data to estimate food chain transfers for radionuclides in various environmental settings. for key elements such as iodine (i) and chlorine (cl), there is a paucity of transfer factor data, particularly outside of agricultural food chains. this study dealt with transfers of i, cl and 28 other elements to foods that would be typical of boreal hunter/gatherer lifestyles, as well as being common foods for modern recreationa ...	2010	20619514
effects of nutrient addition on leaf chemistry, morphology, and photosynthetic capacity of three bog shrubs.	plants in nutrient-poor environments typically have low foliar nitrogen (n) concentrations, long-lived tissues with leaf traits designed to use nutrients efficiently, and low rates of photosynthesis. we postulated that increasing n availability due to atmospheric deposition would increase photosynthetic capacity, foliar n, and specific leaf area (sla) of bog shrubs. we measured photosynthesis, foliar chemistry and leaf morphology in three ericaceous shrubs (vaccinium myrtilloides, ledum groenlan ...	2011	21544572
ecological gradients driving the distribution of four ericaceae in boreal quebec, canada.	understory species play a significant role in forest ecosystem dynamics. as such, species of the ericaceae family have a major effect on the regeneration of tree species in boreal ecosystems. it is thus imperative to understand the ecological gradients controlling their distribution and abundance, so that their impacts can be taken into account in sustainable forest management. using innovative analytical techniques from landscape ecology, we aimed to position, along ecological gradients, four e ...	2015	26140200
an efficient method for high-purity anthocyanin isomers isolation from wild blueberries and their radical scavenging activity.	an efficient process for the purification of anthocyanin monomeric isomers from wild blueberries of lake saint-jean region (quebec, canada) was developed and easy scalable at industrial purpose. the blueberries were soaked in acidified ethanol, filtered, and the filtrate was cleaned by solid phase extraction using silica gel c-18 and dsc-scx cation-exchange resin. anthocyanin-enriched elutes (87 wt.%) were successfully fractionated by preparative liquid chromatography. the major anthocyanins mon ...	2016	26675861
