Two new pentacyclic triterpenoids, namely lantanoic acid (1) and camaranoic acid (2), and six known compounds such as lantic acid, camarinic acid, camangeloyl acid, camarinin, oleanonic acid, and ursonic acid were isolated from the aerial parts of Lantana camara LINN. Structures of the new constituents were elucidated by chemical transformation and spectral studies including 1D (1H- and 13C-NMR) and 2D (1H–1H correlation spectroscopy (COSY), nuclear Overhauser effect spectroscopy (NOESY), 1H–1H total correlation spectroscopy (TOCSY), J-resolved, 1H-detected heteronuclear multiple quantum coherence (HMQC), and heteronuclear multiple bond connectivity (HMBC)) NMR spectroscopy.
