A new triterpenoid (
1) derived from 24-methylcycloartanol was isolated from the leaves of
Oxandra cf.
xylopioides. Anunusual structure of the new compound was assigned as
1, for which the name berenjenol is proposed, on the basis ofthe spectroscopic data of the natural product and of its derivatives
2 and
3. The leaves also afforded the knownmonoterpene isoespintanol (
4). Compounds
1 and
4 significantly reduced the paw edema induced by carrageenan by64% and 43%, at 3 h, respectively. Moreover,
4 reduced IL-1
production by 72% at 100
M and reduced IL-1
mRNA synthesis.
