Abstract
In addition to four previously reported compounds: proximadiol (
1
), 5α-hydroxy-β-eudesmol (
2
), 1β-hydroxy-β-eudesmol (
4
) and 1β-hydroxy-α-eudesmol (
5
), two new sesquiterpenes, 5α-hydroperoxy-β-eudesmol (
3
) and 7α,11-dihydroxy-cadin-10(14)-ene (
6
) were isolated from the unsaponifiable fraction of the petroleum ether extract of
Cymbopogon proximus
STAPF
.
Isolation of compounds
2, 4
and
5
from the genus
Cymbopogon
is reported for the first time. The structure elucidation of these compounds was based primarily on 1D and 2D-NMR analyses.
