Prenylflavonoids from Flourensia fiebrigii
Three flavonoids were isolated from Flourensia fiebrigii, amongst them the 5-deoxyprenylflavonoids ( 1, 2) and 4″-hydroxyprenylflavonoids ( 2, 3), together with known compounds previously determined in the genus. Their structures were established with the aid of spectroscopic analyses. Three compoun...

Summary: | Three flavonoids were isolated from
Flourensia fiebrigii, amongst them the 5-deoxyprenylflavonoids (
1,
2) and 4″-hydroxyprenylflavonoids (
2,
3), together with known compounds previously determined in the genus. Their structures were established with the aid of spectroscopic analyses.
Three compounds: (2
S)-8-(3″-methylbut-2″-enyl)-7,3′,4′-trihydroxyflavanone, (2
S)-8-(3″-methyl-4″-hydroxy-but-2″-enyl)-7,3′,4′-trihydroxyflavanone and (2
S)-8-(3″-methyl-4″-hydroxy-but-2″-enyl)-5,3′,4′-trihydroxy-7-methoxyflavanone, along with five previously known compounds, were isolated from the aerial parts of
Flourensia fiebrigii. Their structures were elucidated by application of various spectroscopic methods, including 1D and 2D NMR techniques. |
