  • Five common invasive plants,Lantana camara Linn,Mikania micrantha Kunth,Mimosa pudica Linn,Praxelis clematidea Cassini and Wedelia trilobata（ L.） Hitchc were extracted with ethanol to detect their antifungal activities on Botryodiplodia theobromae Pat and Colletotrichum gloeosporioides（ Penz.） Penz. ＆ Sacc by using mycelial growth rate method.

Abstract: Five common invasive plants,Lantana camara Linn,Mikania micrantha Kunth,Mimosa pudica Linn,Praxelis clematidea Cassini and Wedelia trilobata（ L.） Hitchc were extracted with ethanol to detect their antifungal activities on Botryodiplodia theobromae Pat and Colletotrichum gloeosporioides（ Penz.） Penz. ＆ Sacc by using mycelial growth rate method. The major components of the extracts were determined by using gas chromatography/mass spectrometry（ GC-MS）. The results showed that the extracts from the five alien invasive plants contained anti-fungal activities against these two fungi and that their inhibition rate of the fungi increased with the concentration of the extracts. Among the extracts the extract of L. camara Linn displayed the highest inhibitory activity on B.theobromae Pat.,with an EC50 being 10. 39 g·L-1. The extracts of Mikania micrantha had strong antimicrobial activity on B. theobromae Pat and C. gloeosporioides（ Penz.） Penz. ＆ Sacc,with the EC50 of 14. 70 g·L-1and14. 77 g·L-1,respectively. GC-MS analysis revealed a total of 14 chemical constituents in the extract of M. micrantha. The major components in the extracts of M. micrantha included 4H-1-Benzopyran-4-one,5,6,7-trimethoxy-2-（ 4-methoxyphenyl）-,Arbutin and 1,2,4-Cyclohexanetriol,which made up 81. 85% of the total content.These components might be the active chemical ingredients which inhibited B. theobromae Pat and C. gloeosporioides（ Penz.） Penz. ＆ Sacc.
