In our study of the antimutagenic activity of
DMSO extract of Sano (Sesbania javanica Miq),
commonly used in the local diet, was observed.
The major flavonoid constituent of the Sano
(Sesbania javanica Miq.) flower was analyzed
using a UV-diode array, ESI-MS, and 1H, 13C
NMR. The quantitative values of this major flavonoid were determined.
