生姜提取物的防污活性研究

以翡翠贻贝(Perna viridisLinnaeus)足部收缩实验和白脊藤壶(Balanus albicostatasPilsbry)金星幼体附着抑制实验检测了生姜(Zingiber officinaleRoscoe)不同组分的防污活性.实验结果表明,在翡翠贻贝足部收缩实验中,生姜的六种提取物防污活性高低及其与硫酸铜的防污活性比较结果如下:乙醇冷提组分=乙醇热提组分>乙酸乙酯热提组分>乙酸乙酯冷提组分>硫酸铜>水冷提组分>水热提组分;在白脊藤壶金星幼体附着抑制实验中,生姜的六种提取物的防污活性高低排序如下:乙醇热提组分>乙醇冷提组分>乙酸乙酯冷提组分>乙酸乙酯热提组分>水冷提组分>水热提组分.本研究结果表明生姜的乙醇冷提组分、乙醇热提组分、乙酸乙酯冷提组分和乙酸乙酯热提组分均具有较高的防污活性,揭示了生姜在海洋防污中有很大的应用和发展潜力,为寻找新型的环保型海洋防污材料以及进一步研究提供了理论依据.

Study on Antifouling Activity of Extracts from Zingiber of ficinale Roscoe

Extracts from Zingiber officinale Roscoe by different solvents and extraction methods was tested for antifouling activity using a foot retraction assay with mussel Perna viridis Linnaeus and a settlement inhibition assay with cyprids larvae of barnacle Balanus albicostatus Pilsbry.As the results shown,in the case of foot retraction assay with mussel P.viridis,the relative potency of extracts and bluestone in antifouling activity was:extract by ethanol at room temperature = extract by ethanol in boiling water > extract by ethyl acetate in boiling water> extract by ethyl acetate at room temperature > bluestone > extract by water at room temperature > extract by water in boiling water;in the other case of settlement inhibition assay with cyprids larvae of B.albicostatus,the relative potency of extracts and bluestone in antifouling activity was:extract by ethanol at room temperature > extract by ethanol in boiling water > extract by ethyl acetate at room temperature > extract by ethyl acetate in boiling water > extract by water at room temperature > extract by water in boiling water.In this paper,extract by ethanol at room temperature,extract by ethanol in boiling water,extract by ethyl acetate at room temperature and extract by ethyl acetate in boiling water from Z.officinale were proven to be of high antifouling activity,suggesting that Z.officinale has great potentialities of application and development and providing data for the search of new environmental friendly marine antifouling coating and further investigation.
