| Abstract: | of Semiaquilegia adoxoides (DC) Makino and exhibited high-level antifeeding activity against Pieris rapae L.and Plutella xylostella (Linnaeus).The experiment proved that petroleum ether abstracts of Semiaquilegia adoxoides (DC) Makino were better than other two abstracts,namely,chloroform and actone.When petroleum ether abstract was separated into oil and crystal abstract,it was proved that petroleum ether oil abstract exhibited a higher level of antifeeding activity than crystal abstract. |
