title: A new 28-noroleanane triterpenoid from the aerial parts of Lantana camara Linn.
abstract: A new 28-norolean-12,17-diene triterpene lantigdienone (1) oxidised at C-11 and C-22 has been isolated from the aerial parts of Lantana camara, along with two known compounds, camarinin (2) and camangeloyl acid (3). The structure of compound 1 was elucidated as 3,25-epoxy-3alpha-hydroxy-22beta-[beta,betadimethylacryloyloxy]-11-oxo-28-norolean-12,17-diene, with the help of spectral studies.
