Abstract

Two novel triterpenoids, lantadienone (1) and camaradienone (2), were isolated from the aerial parts of Lantana camara, along with seven known compounds, lantadene A, lantadene B, β-sitosterol 3-(β-D- glucopyranoside), camaric acid, lantanilic acid, lantanolic acid, and camangeloyl acid. Their structures were elucidated as (3β,22β)-3,25- epoxy-3-hydroxy-22-{[(2Z)-2-methyl-1-oxobut-2-enyl]oxy}-28-noroleana-12, 17-dien-11-one (1) and (3β)-3,25-epoxy-3-hydroxy-28-noroleana-12,17-dien- 11-one (2), respectively, by means of spectral studies. The triterpenoids 1 and 2 represent 28-noroleananes oxidized at C(11) and C(22) or at C(11), reported for the first time.
