从韩国海岸的27种常见的海藻已筛选出的抗氧化活性。在实验室测定中测试海藻提取物对海洋污损的绿色浒苔和蓝色贻贝的抑制作用。组织生长、孢子附着、合子形成和萌发。结果表明，中华石花菜（Ishige sinicola，= I. foliacea）和霍氏马尾藻（Sargassum horneri）。孢子沉降强烈抑制使用提取物浓度低至30 μ g mL（-1）与I。sinicola和120 μ g mL（-1）。horneri。紫丁香甲醇提取物能完全抑制贻贝足的排斥活性。sinicola和Scytosiphon lomentaria，浓度为40 μ g/10穆尔滴。这些提取物也表现出较强的幼虫沉降，分别没有或只有6%的幼虫沉降时，0.8毫克毫升（-）1的测试浓度。这项工作是从海洋大型藻类中开发新型抗菌剂的第一阶段。
Twenty-seven species of common seaweeds from the coast of Korea have been screened for antifouling activity. The seaweed extracts were tested in laboratory assays against the marine fouling green alga Enteromorpha prolifera and the blue mussel Mytilus edulis. Tissue growth, spore settlement, zygote formation and germlings of the E. prolifera were inhibited by methanol extracts of the seaweed Ishige sinicola (= I. foliacea) and Sargassum horneri. Spore settlement was strongly inhibited by using extract concentrations as low as 30 mug mL(-1) with I. sinicola and 120 mug mL(-1) with S. horneri. The repulsive activity of the foot of the mussel was completely inhibited by methanol extracts of I. sinicola and Scytosiphon lomentaria at concentrations of 40 mug per 10 muL drop supplied to each mussel. These extracts also showed strong antifouling activities on larval settlement with, respectively, no or only 6% of the spat settling when a test concentration of 0.8 mg mL(-)1 was used. This work is the first stage towards the development of novel antifouling agents from marine macroalgae.
