Abstract
Purpose:
The purpose of this
investigation was to isolate novel flavonoids from
Alpinia galanga rhizomes.
Methods:
The methanol extract of Alpinia galanga was
subjected to column chromatography and eluted with ethyl
acetate-methanol (9:1) to yield a compound,
galangoflavonoside (AG 11). The structure of the
compound was elucidated by various spectral techniques
(UV, IR, 1H NMR, 13C NMR, and MS).
Results:
Chemical investigation of the extract furnished a new
flavonoid galangoflavonoside (AG 11). Conclusion:
The isolated compound, galangoflavonoside (AG
11,) could be a potential therapeutic compound as well
as serve as a lead compound in the synthesis of other
useful flavonoids. Isolation of the galangoflavonoside
from Alpinia galanga rhizomes is being reported, to the
best of our knowledge, for the first time.
