Abstract By means of solvent partition, preparative TLC and spectral analysis, a main active substance with the biological activity was fraxinellone contained in D.dasycarpus. Its antifeeding rate and mortality of 72h at 0.21% (mass percent) against 3rd armyworm (mythimna separata) were 90.4% and 95.2%, respectively. Then antimicrobial activity of fraxinellone had been tested against 7 kinds of bacteria and 10 kinds of plant diseases. The inhibition rate of fraxinellone at 50ppm reached 100%, 99.8% and 99.8% against Escherichia coli, Staphlococcus aurens and Bacillus megathrium, respectively. Its inhibition rate at 100ppm against Rhizotonia cerealis van der Hoeven apud.Boerema & Verhoeven was 100% and at 50ppm against Colletrichurm lagenarium & verhoeven was 72%. |
