Six compounds were isolated from leaves of Lantana camara. On the basis of chemical and spectral (UV, IR, EI-MS, 1HNMR 13CNMR) analysis, they were identified as oleanonic acid (I), lantadene A (II), lantadene B (III), lantanilic acid (IV), icterogenin (V) and
A new pentacyclic triterpenoid, 3β,25-epoxy-3α,22β,23α-trihydroxy-olean-12-en-28-oic acid (1), together with seven known compounds, including five triterpenoids, β-amyrin (2), lantadene B (3), lantanilic acid (4), lantanolic acid (5) and ursolic acid (6) in addition to β-sitosterol (7) and benzoic
A new compound, 3beta,25-epoxy-3alpha-hydroxy-22beta-isobutanoyloxyolean-12-ene-28-oic acid (1), and two known triterpenoids lantanilic acid (2) and camaric acid (3) were isolated from the stem and leaves of Lantana cujabensis. Their structures were elucidated by spectroscopic methods. The ethanol
Lantanilic acid, camaric acid and oleanolic acid possessing nematicidal activity were isolated from the methanolic extract of the aerial parts of Lantana camara Linn. through bio-assay guided fractionation. These compounds exhibited 98%, 95% and 70% mortality respectively against root-knot nematode
Two new olean-12-ene triterpenoids, camarolic acid (1) and lantrigloylic acid (2), have been isolated from the aerial parts of Lantana camara, along with ten known triterpenes, namely, camaric acid, lantanolic acid, lantanilic acid, pomolic acid, camarinic acid, lantoic acid, camarin, lantacin,
Two new natural triterpenes, lantaninilic acid and lantoic acid, along with the known triterpenes lantadene A, and oleanolic, ursolic, betulinic, lantanolic, and camaric acid, were obtained from the aerial parts of Lantana camara through bioassay-guided isolation, monitoring the in vitro
