Algicidal activity and potential antifouling defenses in macroalgae from the western Antarctic Peninsula including probable synergistic effects of multiple compounds
西南极半岛巨藻的溶藻活性与其潜在的污渍防御能力可能由多种组分协同作用而形成
Abstract: Insoluble crude extract fractions of 11 species of Antarctic macroalgae were screened for algicidal activity against sympatric diatoms. Medium pressure liquid chromatography (MPLC) fractions of soluble extracts of four species were also screened. Levels of activity in insoluble fractions were lower than in previously examined corresponding soluble fractions. Combined MPLC fractions had lower activity than unfractionated extracts in three species, but in two, specific fractions with activity were identified. Combined soluble fractions of a fourth species retained strong activity but no individual fraction had activity even at tenfold higher concentrations, indicating that activity probably results from synergistic interactions between multiple compounds.
摘要：根据对同域硅藻所表现出的不同藻活动，我们筛选了11种南极大型海藻的不溶性粗提物组分，同时还有4种可溶性提取物的中压液相色谱(HPLC)馏分。不溶性组分中的活动水平低于先前已检验过的对应可溶性组分。收集3种中压液相色谱(HPLC)馏分结合后的活性低于未分馏的提取物，不过当2种组分时，我们足以检测到其中特定组分的活性。当与第4种可溶性的馏分结合后仍能够保持很强的活性，但是单独物质的馏分即使浓度增大10倍也无法检测到活性。这说明有可能是多种化合物之间的协同作用促成了活性的产生。 |
