Abstract
Three new flavonoid glycosides (1-3) and nineteen known compounds (4-22) were isolated from the aqueous ethanolic extract of the seed of Oroxylum indicum. The structures of 1-3 were elucidated on the basis of spectroscopic analysis. Antioxidant activities of all the isolated compounds were evaluated using a DPPH and an ORAC assay. Compounds 3, 5-7, 9 and 12 exhibited potent antioxidant activity in the DPPH assay, while compounds 3-15 showed potent antioxidant capacity in the ORAC assay, and seven antioxidant flavonoids (4-6, 8, 9, 11, 12) were detected as the main ingredients in the methanolic extract of seed of O. indicum using an HPLC analysis.Entities:
