摘要
[目的]探讨产自北方地区的博落回(Macleaya cordata)乙醇粗提物的毒力。[方法]利用博落回乙醇粗提物对麦长管蚜和桃粉蚜进行玻片浸渍法室内毒力测定。[结果]麦长管蚜与桃粉蚜24 h的LD50依次为0.052 9 g/L与147.481 8 g/L;而48 h的LD50依次为0.003 9 g/L与0.012 3g/L。[结论]北方地区博落回在蚜虫防治方面有一定的应用价值。
[Objective]The research aimed to study the fermentation conditions of Aspergillus-type Douchi melanoidin.[Method]The effects of fermentation temperature,salt content,Fe3＋ content on the fermentation of Aspergillus-type Douchi melanoidin were investigated by one-factor experiment and orthogonal test.[Result]The results of one-factor experiments showed that under the conditions of 55 ℃,salt content of 10%,Fe3＋ content of 0.10%,the intensity of brown stain was highest.The orthogonal test results showed that the best fermentation conditions of Aspergillus-type Douchi melanoidin was： temperature 55 ℃,content of salt 8%,additive content of Fe3＋ 0.2%.[Conclusion]The fermentation conditions of Aspergillus-type Douchi melanoidin were established.And this result provided scientific references for the formation of melanoidin during the process of fermentation.
