Abstract: A method for preparing a ginko leaves extract and a chestnut bark extract having excellent degrading effects of algae is provided to reduce damages of a lake or river ecology caused by algae, and a method for removing algae using the ginko leaves extract and the chestnut bark extract prepared by the method is provided. A method for removing algae comprises: using a ginko leaves extract extracted through the steps of mixing ginko leaves with 30 to 70% Me-OH, subjecting the mixed solution to sonication and filtering the extracted solution, and a chestnut bark extract extracted through the steps of mixing chestnut bark with distilled water, heating the mixed solution, cooling the heated solution and filtering the cooled solution. The method for removing algae comprises controlling concentration of the ginko leaves extract to a range of 0.01 to 10% of the entire volume, and injecting the concentration-controlled ginko leaves extract into the habitat of algae. The method for removing algae comprises controlling concentration of the chestnut bark extract to a range of 0.5 to 2% of the entire volume, and injecting the concentration-controlled chestnut bark extract into the habitat of algae.

Abstract translation: 提供了具有优异的藻类降解效果的银杏叶提取物和栗子树皮提取物的方法，以减少由藻类引起的湖泊或河流生态的损害，以及使用银杏叶提取物和栗子树皮提取物去除藻类的方法 提供了通过该方法制备的。 一种去除藻类的方法包括：使用通过将银杏叶与30-70％Me-OH混合的步骤提取的银杏叶提取物，对混合溶液进行超声处理并过滤提取的溶液，并通过步骤提取栗子皮提取物 用蒸馏水混合栗子树皮，加热混合溶液，冷却加热的溶液并过滤冷却的溶液。 去除藻类的方法包括将银杏叶提取物的浓度控制在整个体积的0.01至10％的范围内，并将浓度控制的银杏叶提取物注入藻类栖息地。 去除藻类的方法包括将栗子树皮提取物的浓度控制在整个体积的0.5〜2％的范围内，并将浓度控制的栗子皮提取物注入藻类栖息地。
