Isolation of flavonoids from Indigofera heterantha seeds
نویسندگان
چکیده
The seeds of Indigofera heterantha yielded a flavonoid characterized as quercetin 3-O-α-L-rhamnoside along with known 3,5,7-trihydroxy-6,4 ́-dimethoxyflavone and 3,5,4 ́-trihydroxy-6,7-dimethoxyflavone. The isolated compounds were characterized by using modern spectroscopic techniques such as UV, IR, NMR and mass.
