title: A new biologically active flavone glycoside from the seeds of Cassia fistula (Linn.).
abstract: A new bioactive flavone glycoside 1 [mp 252-254 degrees C, C28H32O16, [M]+ 624 (EIMS)] was isolated from the acetone soluble fraction of the defatted seeds of Cassia fistula (Linn.). It was characterized as a new bioactive flavone glycoside 5,3',4'-tri-hydroxy-6-methoxy-7-O-alpha-L-rhamnopyranosyl-(1 --> 2)-O-beta-D-galactopyranoside by several colour reactions, spectral analysis and chemical degradations. Compound 1 showed anti-microbial activity.
