Abstract:
The effects on violet magnolia extraction ratio of petroleum ether，chloroform，ethyl acetate，acetone，ethanol，deionized water were studied with parallel extract methods.The inhibitory effects of 6 kinds violet magnolia parallel extracts on hyphae growth and spore germination of Bocrytis cinerea Pers. pathogen were studied with growth rate and spores germination methods.The results showed that the extracted rate of deionized water was the largest，which was 25.71%.The smallest was petroleum ether which was 9.63%.6 kinds solvent parallel extracts had significant antibacterial effects on hyphae growth and spore germination of pathogen.The EC50 of petroleum ether，chloroform and deionized water extracts on hyphae growth and spore germination was 372.15 mg/L and 1 318.92 mg/L，206.83 mg/L and 591.78 mg/L，6 024.25 mg/L and 3 532.13 mg/L respectively.Indicate that the inhibition effect on hyphae growth was superior to spore germination of organic solvents extracts.And the main inhibiting activity substance of violet magnolia could be extracted by polar organic solvents easily.
