Abstract
Three allelochemicals were isolated from aerial parts of Mikania micrantha by repeated silica gel column chromatography combined with bioassay method.Their structures were identified as α-amyrin,stigmasterol and ferulic acid by spectroscopic analysis(IR,EI-MS,1HNMR,13CNMR).The α-amyrin and ferulic acid had highly inhibitory effects on the seedling growth of Raphanus sativus,Brassica campestris and Oryza sativa at 1 000,500 and 250 μg·mL-1,respectively.
