title: Flavonoid glycosides from the aerial parts of Acacia pennata in Myanmar.
abstract: Phytochemical investigations of the aerial parts of Acacia pennata (Mimosaceae) from Myanmar led to the isolation of five flavonoid glycosides and six known compounds. The new compounds were identified as (2R,3S)-3,5,7-trihdyroxyflavan-3-O-α-L-rhamnopyranoside, (2S)-5,7-dihydroxyflavan-7-O-β-D-glucopyranoside-(4α → 8)-epiafzelechin-3-O-gallate, (2R)-4',7-dihydroxyflavan-(4α → 8)-(2R,3S)-3,5,7-trihdyroxyflavan-3″-O-α-L-rhamnopyranoside, 5,7-dihydroxyflavone 6-C-β-boivinopyranosyl-7-O-β-D-glucopyranoside, and 5,7-dihydroxyflavone 7-O-β-D-glucopyranosyl-8-C-β-boivinopyranoside based on interpretation of spectroscopic data.
