Abstract
The isolation of 6-hydroxyluteolin-7-O-(1"-alpha-rhamnoside) from the Central American epiphyte Vriesea sanguinolenta Cogn. and Marchal (Bromeliaceae) is described here. Its stereostructure was established by spectroscopic methods and an X-ray structure analysis of its hepta-O-acetyl derivative. This flavonoid glycoside had previously been reported from some Teucrium species (Labiatae), yet without sufficient physical data and spectroscopic evidence.
