Abstract
Two new pentacyclic triterpenoids lancamarinic acid and lancamarinin have been obtained from the aerial parts of Lantana camara Linn. They were characterized as 22β-acetoxy-3,25-epoxy-3α-hydroxyolean-12-en-28-oic acid and methyl 3,25-epoxy-3α-hydroxy-11-oxo-22β-senecioyloxyolean-12-en-28-oate, respectively, through chemical transformation and exhaustive spectroscopic studies.
