Abstract
Hundreds of plant species, including many economically important crop plants, are attacked by a highly destructive soil-borne fungus Macrophomina phaseolina (Tassi) Goid. In the present study, methanolic root extract of septicweed [Senna occidentalis (L.) Link] was evaluated against M. phaseolina. Different concentrations of the extract (0.5 to 3.0%) considerably decreased fungal biomass by 33–43%. Nine compounds were recognized when the extract was analyzed by GC-MS. The major compound was 11-octadecanoic acid, methyl ester (26.49%) followed by (5β)pregnane-3,20β-diol, 14α d-mannose (13.85%);, 18α-[4-methyl-3-oxo-(1-oxa-4-azabutane-1,4-diyl)]-, diacetate (13.61%); ethyl iso-allocholate (11.37%); pentadecanoic acid, 14-methyl-, methyl ester (11.01%); and 9,12-octadecadienoic acid, methyl ester, (E,E)- (9.76%), which might be the cause of antifungal activity.
数百种植物，包括许多经济上重要的作物植物，受到一种极具破坏性的土传真菌的攻击。在本研究中，septicweed的甲醇根提取物[Senna occidentalis (L.)]Link]对菜绿分枝杆菌的抗性进行了评价。不同浓度的提取物(0.5 ~ 3.0%)显著降低真菌生物量33€43%。通过GC-MS分析，鉴定出9个化合物。主要化合物为11-十八烷酸甲酯(26.49%)，其次为(5β)孕烷-3,20β-二醇，14αd-甘露糖(13.85%)，18α-[4-甲基-3-氧-(1-氧-4-阿扎丁烷-1,4-二基)]-，二乙酸酯(13.61%);异胆酸乙酯(11.37%);十五酸14-甲基甲酯(11.01%);9,12-十八二烯酸甲酯，(E,E)-(9.76%)，这可能是抗真菌活性的原因。
