Popis: | The hydrodistillation products of the liverworts Marsupella emarginata , M. aquatica and M. alpina were investigated by spectroscopic methods. A number of new compounds could be isolated by preparative gas chromatography (GC) and identified by spectroscopic techniques including GC-mass spectrometry, NMR and chemical correlations in conjunction with enantioselective GC. From M. emarginata , in addition to many known compounds, the sesquiterpene hydrocarbon (−)-7- epi -eremophila-1(10),8,11-triene ( 1 ) and the sesquiterpene derivatives (−)-4- epi -marsupellol ( 2 ), (−)-marsupellol acetate ( 18 ), (−)-4- epi -marsupellol acetate ( 4 ), (+)-5-hydroxymarsupellol acetate ( 5 ) and (−)-9-acetoxygymnomitr-8(12)-ene ( 24 ) could be identified. In M. aquatica the sesquiterpene hydrocarbons (−)-myltayl-8(12)-ene ( 7 ), ent -(+)-amorpha-4,11-diene ( 8 ), (−)-amorpha-4,7(11)-diene ( 9 ), the sesquiterpene alcohol (+)-9-hydroxyselina-4,11-diene ( 10 ) and (−)-2-acetoxyamorpha-4,7(11)-diene ( 11 ) were identified. In M. alpina (−)- trans -selina-4(15),11-dien-5-ol ( 12 ), (+)-8,9-epoxyselina-4,11-diene ( 13 ) and (+)- cis -selina-4(15),11-dien-5-ol ( 14 ) were found as new natural products. |
