摘要

海藻由绿藻、褐藻和红藻组成,是公认的富含生物活性酚类化合物的宝贵海洋资源,具有营养保健潜力。尽管人们对可食用物种的兴趣日益浓厚,但对海藻的关注有限,这可能是一种未被充分开发的生物活性来源,同时也解决了生态挑战。本研究建立了一种创新的、基于结构的数据处理流程,用于表征海洋生物中酚类化合物的特征,并通过非靶向质谱数据采集应用于来自主要分类类群的8种食用海藻和2种侵染海藻。结果显示,不同海藻分类群的酚类物质分布不同,绿藻显示出酚和酚酸硫酸盐的最高丰度,而褐藻则以苯酞酸为主。硫酸盐酸化的酚类物质数量超过非硫酸盐酸化的酚类物质,强调了海洋特定代谢物专用分析工作流程的重要性。多变量统计分析进一步区分了海藻的酚含量和化合物类别,侵染海藻的酚含量与可食用海藻相当。这表明,与蓝色经济原则一致,将有害的海藻作为生物活性化合物的可持续来源具有潜力。我们的研究结果提供了对海藻酚类物质化学多样性的全面见解,并突出了未开发的入侵物种在营养保健应用中的潜力,有助于可持续的海洋资源管理和功能食品的开发。

Seaweeds, comprising green (Chlorophyta), brown (Phaeophyta), and red (Rhodophyta) algae, are recognized as valuable marine resources rich in bioactive phenolic compounds with nutraceutical potential. Despite growing interest in edible species, limited attention has been given to infesting seaweeds, which may represent an underexploited source of bioactives while addressing ecological challenges. In the present study, an innovative, structure-based data processing workflow was set up for the characterization of phenolic compounds in marine organisms and applied to eight edible and two infesting seaweed species from the major taxonomic groups by means of untargeted mass spectrometric data acquisition. The results reveal distinct phenolic profiles across seaweed taxa, with green algae exhibiting the highest abundances of phenol and phenolic acid sulfates, while brown algae were characterized by a predominance of phlorotannins. Sulfated phenolics outnumbered their non-sulfated counterparts, underscoring the importance of dedicated analytical workflows for marine-specific metabolites. Multivariate statistical analyses further distinguished seaweed classes based on phenolic content and compound classes, with infesting seaweeds demonstrating comparable phenolic profiles to their edible counterparts. This suggests the potential for valorizing infesting seaweeds as sustainable sources of bioactive compounds, aligning with Blue Economy principles. Our findings provide comprehensive insights into the chemical diversity of seaweed phenolics and highlight the unexplored potential of invasive species for nutraceutical applications, contributing to sustainable marine resource management and the development of functional foods.
