| Abstract: | A new triterpene, lancamarolide ( 1 ), and seven known triterpenes, oleanonic acid ( 2 ), lantadene A ( 3 ), 11α‐hydroxy‐3‐oxours‐12‐en‐28‐oic acid ( 4 ), betulinic acid ( 5 ), lantadene B ( 6 ), and lantaninilic acid ( 7 ) were isolated from the aerial parts of Lantana camara in the course of bioassay‐guided isolation, and their nematicidal activities against Meloidogyne incognita, the root knot nematode, were carried out. Oleanonic acid was found to be the most active compound and exhibited 80% mortality after 72 h at 0.0625% concentration, which is comparable with that of the standard furadan. |
