berry Sea buckthorn (Hippophae rhamnoides) The Canadian-grown fruit shows promising health benefits driven by its rich and diverse polyphenol profile and should be considered for further commercial expansion as a bioactive-loaded superfruit.
Sea buckthorn is a deciduous, spiny plant that grows along the coasts of northwestern Europe and in temperate regions of central Asia.
Its fruits and leaves are widely used Sea buckthorn oil has nutritional, medicinal, and functional properties and is rich in omega-3 and omega-6 fatty acids, vitamins E, B, A, and polyphenols.
The plant was introduced in Canada in the early 2000s following research into the crop's commercial potential by government agencies.
“Sea buckthorn is a unique crop with great potential for use,” said Dr. Renan Danielski. student at the University of Newfoundland.
“Popular in Asia and northwestern Europe, there is an opportunity to replicate this success in North America by leveraging the unique qualities of locally grown varieties.”
Danielski and Professor Fereydoun Shahidi of Memorial University of Newfoundland were motivated by the experimental status and limited commercialization of sea buckthorn in North America to date, and research on the antioxidant properties of Canadian cultivars. We set out to characterize the unique composition of polyphenols, a type of chemical compound.
“Understanding how our varieties compare globally will help us communicate our benefits to consumers and establish our presence in the market,” Professor Shahidi said.
The findings highlight the presence of key polyphenolic compounds in sea buckthorn pomace and seeds, each boasting potential health benefits ranging from cardiovascular protection to anti-inflammatory properties. .
Importantly, geographic factors influence the polyphenol profile of sea buckthorn berries, and researchers found that several different compounds with enhanced bioactivity are present only in sea buckthorn varieties grown in Newfoundland. is that we have identified.
Additionally, sea buckthorn extract has demonstrated promise in vitro It has anti-diabetic and anti-obesity potential, paving the way for further research into its mechanisms and potential therapeutic applications.
“This is a first step toward understanding how sea buckthorn polyphenols can modulate our physiology in beneficial ways,” Danielski said.
“Future research should focus on understanding the mechanisms behind those effects and further experiments using animal models and humans.”
“If these effects are confirmed, in vivoWe can imagine using sea buckthorn polyphenols for therapeutic and pharmacological purposes to help prevent and treat diabetes, obesity, and many other conditions. ”
