New Triterpenes of Lantana camara. A Comparative Study of the Constituents of Several Taxa

Abstract: The triterpenes of Lantana camara vary widely between taxa. In taxa toxic to livestock 22β-angeloyloxy-3-oxoolean-12-en-28-oic acid (lantadene A) and 22β-dimethylacryloyloxy-3-oxoolean-12-en-28- oic acid (lantadene B) are present, usually as major constituents, although 3-oxolup-20(29)-en-28-oic acid (betulonic acid) predominates in the taxon Helidon White. 22β-Angeloyloxy-3β-hydroxyolean- 12-en-28-oic acid, 22β -dimethylacryloyloxy-3β -hydroxyolean-12-en-28-oic acid and 22β-hydroxy-3-oxoolean-12-en-28-oic aci… Show more

“…Most of the compounds, namely 1-39, are based on the oleanane nucleus. Among the triterpenes with an oleanane nucleus, nineteen (1-19) have a common skeleton (Skeleton-I), ten (25-34) have Skeleton-II, two compounds (36, 37) have a common skeleton (Skeleton-III), and the other two Hart et al (1976aHart et al ( , 1976b …”

“…In spite of having many toxic effects this weed is also having anticancer (Gomes et al, 2010;Sathish et al, 2011), antibacterial (Rwangabo et al, 1988;Barreto et al, 2010), antifungal (Sharma et al, 2007), anti-diabetic (Garg et al, 1997), anti-inflammatory, analgesic, antimotility (Ghosh et al, 2010, anti-feedant, larvae repellent (Moffitt et al, 2010), anticonvulsant (Bisi-Johnson et al, 2011), antiulcer and antioxidant actions (Sathish et al, 2011). Oleanolic acid and ursolic acid are the major components, while LA and LB are the minor constituents obtained from Townsville prickly orange variety of lantana (Hart et al, 1976a). …”

“…The aqueous layer was further extracted with n-BuOH to give a n-BuOH soluble fraction and the aqueous layer. The AcOEt fraction showed the most potent anti-androgenic activity and was fractionated as described in the Experimental section to give new triterpenes, 1-6, along with known triterpenes, lantanolic acid (7), 4) 3-epipomolic acid (8), 5) lantic acid (9), 4) icterogenin (10), 6) lantadene A (11), 7) lantadene B (12), 7) ursomic acid (13) 8) and pomonic acid (14), 9) and the flavonols pachypodol (15) 10) and retusin (16), 11) which were recently reported as anti-emetic principles of Pogostemon cablin. 12) The high resolution (HR)-FAB-MS of 1 afforded a pseudo molecular ion [MH] ϩ at m/z 529.3533, corresponding to the molecular formula C 32 H 48 O 6 .…”
