| Summary: | ABSTRACT
Two flavonoids, 6C,7-O-dimethyl aromadendrin
(1) have and ploretin (2) been isolated from the
bark of Bauhinia excelsa. The structure of 6C,7-
O-dimethyl aromadendrin (1) have and ploretin
(2) been elucidated based on its spectroscopic
data, including UV, MS 1D and 2D NMR spectra.
The activity of radical scavenging against
2,2-diphenyl-1-picrylhydrazyl (DPPH), showing
their IC50 were 1512.1 μM. The results indicate
that as 6C,7-O-dimethyl aromadendrin and
phloretin were inactive |
