摘要
INTRODUCTION: as seaweeds are constantly exposed to oxidative stress conditions, significant quantities of antioxidant compounds are found in their chemical composition such as lypophilic compounds like unsaturated fatty acids, chlorophyll and carotenoids; hydrophilic compounds like polyphenols and vitamin C, and polysaccharides. OBJECTIVES: to review and analyze scientific information about the potentialities of seaweeds as source of natural antioxidants in relation with their chemical composition. METHODS: publications related to seaweeds′ chemical composition and antioxidants properties were thoroughly analyzed and included in the review. RESULTS: the study of seaweeds as natural antioxidants is closely related to their chemical composition, and is at present an important field in natural products research, due to seaweed potentialities for human health and food industry. Nevertheless, it is frequently a challenge to exactly determine the compounds responsible for the antioxidant activity and sometimes, this activity may come from a synergistic effect is found among several compounds. CONCLUSIONS: seaweeds are organisms with wide biodiversity that might become a significant source of natural antioxidants.

引言：作为海藻经常暴露于氧化应激的条件下，显著量的抗氧化剂化合物的存在于它们的化学成分，例如亲脂化合物如不饱和脂肪酸，叶绿素和类胡萝卜素;亲水化合物如多元酚和维生素C，和多糖。目标：审查和分析有关海藻的潜力源天然抗氧化剂与它们的化学成分相关的科学信息。方法：与海藻“的化学成分和抗氧化剂性质的出版物进行了深入分析，并列入审查。结果：海藻的天然抗氧化剂的研究有密切关系它们的化学组成，并且是在天然产物的研究本的一个重要领域，由于海藻潜力为人类健康和食品工业。然而，它往往是一个挑战，准确地确定负责抗氧化活性，有时化合物，这种活性可能是来自一个协同效应的几种化合物中发现的。结论：海藻与宽多样性可能成为天然抗氧化剂的显著来源生物。
