飞机草(Eupatorium odoratum Linn.)活性物质对有毒蓝藻铜绿微囊藻(Microcystis aeruginosa Kutzing.var.minor.H.W.Liang.,记作:NIES298)和鱼害微囊藻(Microcystis ichthyoblabe Kutz.,记作:TAC95)具有增殖抑制作用.飞机草不同溶剂的浸提液对NIES298和TAC95的抑制效果:蒸馏水浸提比乙醇、丙酮抑制效果好.层析分离活性成分后,发现D3(Rf=0.524)的分离使用物剂对量两的种加蓝大藻,的两抑种制蓝作藻用的非叶常绿明素显a,浓74度μ明g/显g低时于即起己始表值现.出抑制作用,并且随着飞机草浸提液使用剂量的加大,两种蓝藻的叶绿素a浓度明显低于起始值.
(Eupatorium odoratum Linn.) Active substance against Microcystis aeruginosa (Microcystis aeruginosa Kutzing.var.minor.HWLiang., Written as: NIES298) and Microcystis ichthyoblabe Kutz. (Written as: TAC95) had inhibitory effect on proliferation of NIES298 and TAC95.The inhibitory effect of extracts of Anemarrhenae aspartat on NIES298 and TAC95 was better than ethanol and acetone in distilled water.After chromatographic separation of active ingredients, the separation of D3 (Rf = 0.524) was found The use of agents on the amount of two kinds of blue-green algae, the two kinds of inhibition of blue-green algae used for non-leaf evergreen Ming significant a, 74 ° μ g / g g The results showed that the concentration of chlorophyll a in the two cyanobacteria was significantly lower than the initial value with the increase of the dosage of the extract of the airplane grass.
