description |
Thirty-one species from Zingiberacea family were screened for their
antioxidant (FTC method), antimicrobial (disc diffusion method), and
antitumour promoting (EBV EA assay method) activities. Three species,
A lpinia zerumbet, A lpinia rfflesiana and Etlingera elatiar, were selected for
further study, based on their promising preliminary biological activities.
Five known compounds were isolatpd hom the rhizomes of Alpinia
zerumbet, namely S,6-dehydrokawain, flavokawin B, l,7-diphenyl-Shydroxy-
6-heptene-3-one, (-)-pinocembrin, and a mixture of stigmasterol
and β-sitosterol. From the fruits of Alpinia raffiesiana, seven compounds
were isolated, namely 5,6-dehydrokawain: flavokawin B, l,7-diphenyl-5-
hydroxy-6-heptene-3-one, (-)-pinocembrin, cardamonin, (-)-pinostrobin,
and 2',3',4',6' -tetrahydroxychalcone. This is the first report on the isolation
of 2',3',4',6' -tetrahydroxychalcone from Alpinia. |
