Abstract Fifteen attached macroalgae from the Madeira Archipelago, comprising three green, three red and nine brown algal species, as well as two beach-cast macroalgal samples, collected along the north shore of Gran Canaria, were assessed for their biochemical properties. The analysis included the determination of total minerals, total carbohydrates, protein, lipids, chlorophyll a, total carotenoids, total phenolic content, fucoxanthin and phycobilins (allophycocyanin, phycocyanin and phycoerythrin). The results showed a high variability of biochemical composition, allowing for the targetting of specific bioresources for particular purposes, including functional foods. This work provides the foundation for a biorefinery strategy implementation plan, for which specific macroalgae may be targeted for valuable and beneficial compounds.

马德拉群岛附着的大型藻类和加那利群岛的海滩养殖大型藻类的生化研究：多变量分析以确定生物资源潜力

摘要 对来自马德拉群岛的 15 种附着的大型藻类，包括三种绿色、三种红色和 9 种棕色藻类，以及沿大加那利岛北岸收集的两种海滩大型藻类样品进行了生化特性评估。分析包括测定总矿物质、总碳水化合物、蛋白质、脂质、叶绿素 a、总类胡萝卜素、总酚含量、岩藻黄质和藻胆素（别藻蓝蛋白、藻蓝蛋白和藻红蛋白）。结果显示生化成分的高度可变性，允许将特定生物资源用于特定目的，包括功能性食品。这项工作为生物精炼战略实施计划奠定了基础，为此可以针对特定的大型藻类生产有价值和有益的化合物。
