A NEW GLYCOSYLATED FLAVONOID, 7-O-α-L-RHAMNOPYRANOSYL-4'-O-RUTINOSYLAPIGENIN, IN THE EXUDATE FROM GERMINATING SEEDS OF Sesbania rostrata

Article abstract of DOI:10.1016/0008-6215(89)84038-8

The title apigenin triglycoside was isolated (4 mg/6000 seeds) by reversephase column chromatography as the major u.v.-absorbing compound in the exudate of germinating seeds of Sesbania rostrata.The structure was assigned on the basis of u.v. spectra, f.a.b.-mass-spectral and 2D-n.m.r. data.The triglycoside was released continuously from the germinating seeds, but at a decreasing rate during the first two weeks.
