A toxin fraction was obtained from Lantana camara L (red variety) leaves by batch extraction and column chromatography on silica gel (60-120 mesh). The main constituents of the toxin preparation were lantadene A and lantadene B and it was devoid of reduced lantadene A. Oral administration (125 mg/kg
Toxic Lantana camara taxa growing in Queensland all contain the triterpene acids lantadene A, reduced lantadene A and lantadene B. These when dosed as pure compounds orally to sheep were similarly toxic at 65 to 75, 42 to 80 and 200 to 300 mg/kg body weight respectively, causing jaundice,
Lantana poisoning in ruminants results from the ingestion of toxic varieties of the plant Lantana camara, which contain the triterpene acids lantadene A and lantadene B. Poisoning results in intrahepatic cholestasis and the consequences of the liver injury include jaundice, photosensitisation and
