简介：目的马尾藻类海草wightiiGreville是属于有大约200种类的Sargassaceae家庭的海洋的棕色的水藻。整个干燥植物粉末的ethanolic摘录包含了众多的phytoconstituents，包括flavonoids。学习在老鼠集中于马尾藻类海草wightii的anticancer活动。在二剂量的马尾藻类海草wightii(EESW)的ethanolic摘录铺平的方法被用来用DAL房间线在老鼠检验anticancer活动导致癌症。身体重量，可行、不能生存的肿瘤房间计数，吝啬的幸存时间，寿命的增加，和hematological参数为EESW的anticancer活动被观察。在老鼠的DAL房间的intraperitoneal接种显著地增加了的结果癌症房间计数。在在对待EESW的组癌症动物观察的癌症细胞数字的减少显示测试药在肿瘤细胞增长上有重要禁止的效果。有EESW的治疗也在肿瘤重量显示出重要减少，并且因此增加了对待DAL的老鼠的lifespan。另外，EESW管理显著地在对待DAL的老鼠恢复了hematological参数。现在的学习结果建议摘录提议的那个政府的结论提高了抗氧化剂潜力。因此，EESW拥有anticancer活动，这能从这研究被结束。
