Title: An NMR Study on Two Semi-Synthetic Pennogenin Saponins
Abstract: 1D and 2D NMR,including 1H NMR,13C NMR,DEPT,HSQC,HMBC) methods were used to elucidate the structures of two semi-synthetic pennogenin compounds: pennogenin-3-O-α-L-rhamnopyranosyl-(1→2)-α-D-glucopyranoside(1) and pennogenin-3-O-{α-L-rhamnopyranosyl-(1→2)-[α-L-rhamnopyranosyl-(1→4)]}-α-D-glucopyranoside(2).The 13C and 1H NMR chemical shifts of these two compounds were assigned and analyzed.No identical structures were found in the natural products.
