Three new pentacyclic triterpenoids, camaryolic acid (1), methylcamaralate (2) and camangeloyl acid (3) and six known compounds beta-sitosterol 3-O-beta-D-glucopyranoside (4), octadecanoic acid (5), docosanoic acid (6), palmitic acid (7), camaric acid (8) and lantanolic acid (9) were isolated from
Eight triterpenoids were isolated from the roots of Lantana camara. On the basis of their chemical properties and spectral data (UV, IR, MS, 1HNMR, 13CNMR), they were identified as lantanolic acid (I), 22 beta-O-angeloyl-lantanolic acid (II), oleanolic acid (III), 22 beta-O-angeloyl-oleanolic acid
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
Lantana camara afforded a novel triterpene 22 beta-acetoxylantic acid and the known triterpenes, lantic acid, 22 beta-dimethylacryloyloxylantonolic acid, a mixture of 22 beta-dimethylacryloyloxy lantanolic acid and 22 beta-angeloyloxylantanolic acid and lantanolic acid. 22 beta-Acetoxylantic acid
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,
