title: A novel bioactive flavonol glycoside from Teramnus labialis spreng.
abstract: A novel biologically active flavonol glycoside (1), C26H28O17, m.p. 216-217 degrees C, was isolated from the chloroform soluble fraction of the ethanol extract of the stems of Teramnus labialis. Its structure was characterized as 3,5,7,3',4',5'-hexahydroxyflavone-3-O-beta-D-glucopyranosyl(1-->3)-O-alpha-L-arabinopyranoside by spectral analysis. The chloroform extract of compound (1) showed antibacterial and antifungal activities.
