九种中药植物提取物对铜绿微囊藻生长的影响

Effect of Extracts from Nine Traditional Chinese Medicines on the Growth of Microcystis aeruginosa

以铜绿微囊藻为供试藻类,从吴茱萸、香加皮、苍耳子、川楝子、仙茅、山豆根、白附子、半夏、苦杏仁等九种中药植物(TCMs)中提取出活性物质,研究提取物对铜绿微囊藻的生长影响.实验表明,吴茱萸、香加皮、苍耳子对铜绿微囊藻的生长具有较好的抑制作用,7d后叶绿素去除率达到了70%以上.其中吴茱萸的抑藻作用最明显,7d后叶绿素去除率为92%以上,14d后叶绿素去除率达98%以上.

Algicidal effect of active substances extracted from nine traditional Chinese medicines（TCMs） including Evodia rutaecarpa,Cortex periplocae,Fructus xanthii,Fructus toosendan,Rhizoma curculiginis,Radix sophorae tonkinensis,Rhizoma typhonii gigantei,Rhizoma pinelliae,Semen armeniacae amarum were examined respectively for their algicidal effects and their influence on the growth of Microcystis aeroginosa.The removal rates of extracts from Evodia rutaecarpa,Cortex periplocae,Fructus xanthii to chlorophyll-a could reach above 70% within 7d,and the best removal effect appeared in the extracts from Evodia rutaecarpa,with 92% removal rate of chlorophyll-a within 7d and 98% removal rate with 14d.
