Its structure was determined to be 3-O-a-L-arabinopyranosyl-(13)-b-D- xylopyranosyl siaresinolic acid on the basis of spectroscopic evidences, especially 2D NMR techniques.展开更多

The structures of monepalosides K and L were determined to be 3-O-α-L-arabinopyranosyl-(1-3)-α-D-xylopyranosyl siaresinolic acid (1) and 3-O-β-D-glucopyranosyl-( 1-3)-β-L-arabinopyranosy1 siaresinolic acid 28-O-β-D-glucopyranosyl-(1-6)-β-D-glucopyranoside (2) respectively, on the basis of chemical and spectroscopic evidence.展开更多
