Nowadays, algae are becoming more and more popular as a food group rich in nutrients, cosmetic raw materials full of antioxidants or valuable dietary supplements. They are of interest for the industry because they are found almost all over the world, in all climatic zones, both in fresh and salt waters. The aim of this study was to take a broad look at green algae (Chlorophyta) and to show how large the variability of the content of active compounds may depend on the species and the place and time of sample collection. Particular attention was paid to compounds with antioxidant activity, whose simplified profiles were created on the basis of complementary, semi-quantitative methods. Additionally, time-yield extraction optimizations were performed. Three different specimens of were compared: from the coastal zone of the Baltic Sea, from the open Baltic Sea area around Bornholm and ( polymorph) from the Atlantic Ocean. The studied algae of the genera were three different species of freshwater algae from various habitats: a lake (), a river () and aquarium farming ( syn. ). The content of antioxidants and the extraction efficiency varied significantly depending on the species.
如今，藻类作为一种富含营养的食物、富含抗氧化剂的化妆品原料或有价值的膳食补充剂，越来越受到人们的关注。它们对工业界有吸引力，因为它们几乎遍布世界各地，在所有气候带，无论是淡水还是咸水都有分布。本研究的目的是广泛研究绿藻（Chlorophyta），并展示活性化合物含量的可变性可能取决于物种以及样本采集的地点和时间。特别关注具有抗氧化活性的化合物，根据互补的半定量方法创建了其简化的图谱。此外，还进行了时间-产量提取优化。比较了三种不同的 样本：波罗的海沿海地区、博恩霍尔姆周围的开阔波罗的海地区和来自大西洋的 （ polymorph）。研究的 属藻类是来自不同生境的三种淡水藻类：一种是湖泊中的（），一种是河流中的（），还有一种是水族馆养殖的（ syn. ）。抗氧化剂的含量和提取效率因物种而异，差异显著。
