Résumé en langage clair

On a global basis consumers’ demand for high-quality, safe, and healthy food is increasing. Among them, disease prevention and maintaining good health have emerged as major driving forces for consumer food preferences. Prairie berries, including Vitis riparia (wild grape), Prunus virginiana L (chokecherry), Ribes hirtellum (gooseberry) and Amelanchier alnifolia L (Saskatoon berry), are cold hardy fruits consumed by prairie Canadians, including the indigenous population and are widely distributed in the prairie provinces. Phenolic compounds are an important group of bioactive molecules present in berries. Due to the high antioxidant activity of polyphenols, there has been an increasing interest in identifying their potential health benefits. Recent findings have shown that diets rich in antioxidants protect humans against degenerative diseases such as diabetes, cancer, and neurogenerative and cardiovascular diseases. This research aimed to examine the phenolic compound compositions of fifteen different berries thereby identifying potential bioactive compounds and metabolite markers unique to each crop using High-resolution mass spectrometry with liquid chromatography (LC-HRMS). We have identified 70 phenolic compounds present in the selected berries. Wild grapes were rich in phenolic compounds such as resveratrol (4.2±0.02 µg/g), while gooseberries were rich in isoquercetin (84.8±0.08 µg/g) and paracoumaric acid. Moreover, saskatoon berries were rich in chlorogenic acid and quercetin. Rutin-trihydrate and chlorogenic acid were the most abundant phenolic compounds in chokecherry. The information from this study may help in finding applications for these different prairie berries in the food, nutraceutical, and pharmaceutical industries.

Recent findings have shown that diets rich in antioxidants protect humans against degenerative diseases such as diabetes, cancer, and neurogenerative and cardiovascular diseases. This research aimed to examine the phenolic compound compositions of fifteen different berries, including wild blueberries (Vaccinium corymbosum), wild raspberries (Rubus idaeus), and Sea Buckthorn (Hippophae rhamnoides) thereby identifying potential bioactive compounds and metabolite markers unique to each crop using High-resolution mass spectrometry with liquid chromatography (LC-HRMS). We have identified 70 phenolic compounds present in the selected berries.
