Data di Pubblicazione:

Abstract:
The flavonoid fraction from the butanol extract of a Mediterranean sample of the seagrass
Halophila stipulacea was chemically analyzed. A new malonylated flavone glucoside, genkwanin-
40-O-(6"-malonyl-glucopyranoside) (3), was isolated together with known flavone
glucosides 4-9, previously reported only from terrestrial sources. The structure of 3 was
established by means of spectroscopic techniques, mainly NMR methods.
