Sesquiterpenes from Cymbopogon proximus
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...

| description | 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. |
