The importance of bioactive derivatives as functional ingredients has been well recognized due to their valuable health beneficial effects. Therefore, isolation and characterization of novel functional ingredients with biological activities from marine algae have gained much attention. Sterols are important structural component of cell membranes. It has been reported that plant sterols exhibit various beneficial biological activities such as hypercholesterolemic, antioxidant, anticancer, antidiabetic, antihypertensive, anti-inflammatory, antifungal, and antibacterial activities. Marine algae with a great diversity can be a very interesting natural resource of sterols. This chapter focuses on biological activities of marine algae derived sterols with potential health beneficial applications in functional foods and pharmaceuticals.
由于生物活性衍生物具有宝贵的健康有益作用，其作为功能成分的重要性已得到充分认可。因此，从海藻中分离和鉴定具有生物活性的新型功能成分备受关注。甾醇是细胞膜的重要结构成分。据报道，植物甾醇具有多种有益的生物活性，如降胆固醇、抗氧化、抗癌、抗糖尿病、抗高血压、抗炎、抗真菌和抗菌活性。种类繁多的海藻可能是甾醇的一个非常有趣的天然来源。本章重点介绍海藻衍生甾醇在功能食品和药物中潜在的有益健康应用方面的生物活性。
