In order to determine the active compounds from Denis cavaleriei vines and their antifeedant activities against Plutella xylostella larvae,the active compounds were isolated by activity-guided fractionation with column chromatography and identified on the basis of MS and NMR data,and antifeedant activity was determined by sandwich method.The results showed that four compounds,isolonchcarpin (A),Magnificol (B),ovalifla,vanone (C) and millettocaiyxin C (D) had been isolated from the plant vines for the first time.Isolonchcarpin,Magnificol and...
