摘要
A new flavonol oligosaccharide, quercetin-3-O-[b-D-xylopyranosyl-(12)- a-L-rhamnopyranosyl-(16)]-b-D-glucopyranoside-3-O-b-D-glucopyranoside, named aescuflavoside was isolated from Aesculus chinensis. Its structure was elucidated by spectra FAB-MS, 1D NMR and 2D NMR including 1H NMR, 13C NMR, HMQC and HMBC techniques.
