| Abstract: |
Two flavonoids and two
carboxylic acids have been isolated from the ethyl acetate extract of the
roots. The structures of these compounds have been established as
myricetin-3,3′,5′,7-tetra methyl ether 1,
ampelopsin-3′,4′,5′,7-tetramethyl ether 2,
plumbagic acid 3 and roseanoic acid 4 on the basis of UV, IR, 1H
and 13 C
NMR and mass spectrum studies. The two carboxylic acids 3 and 4 are reported here
for the first time. Compounds 1 and 2 are the first report from the genus plumbago.
