| Abstract: | From the preliminary screening, it was found that the ethanol extracts from Thermopsis lanceolata R.Br could inhibit G.cingulata effectly. Four constituent parts were separated from the ethanol extracts of T.lanceolata under conditions of certain pH and using certain solvents. Biassay showed that the total alkaloids was strongest portion to inhibit the fungus. The total alkaloid were stronger activity to inhibit germination of the conidia of G.cingulata than that to inhibit the hyphae growth of the fungus, their EC50 were 136.0 μg/mL and 1 555.0 μg/mL respectively. |
