Abstract:

The optimal extracting technological conditions of flavonoids from soybean hull by orthogonal plan method and its nematicidal activity were studied.The result indicated that the conditions of 70℃,10:1 of 80% ethanol to soybean hull,heating and refluxing for 24 h were optimium，the extractive ratio could be up to 8.58% and was higher than Hypo-optimal conditions significantly；The total flavonoids of the extractive solution had high nematicidal activity against the second juvenile(J2),and with the in creasing of concentration，the nematicidal activity was improved，more than 50% of J2 could be killed with the treatment of 1.5 μgmg^-1total flavonoids extraction.In addition,it also had inhibition on eggs hatch to some extent,but inhibition rate of eggs hatch was below 50%
