摘要	Nine protopanaxatriol glycosides isolated from mild acid hydrolysis products of crude root saponins of Panax notoginseng were identified as 20(R)-ginsenoside-Rh1, 20(S)-ginsenoside-Rh1, ginsenoside-Rg1, -Re and -Rg2, notoginsenoside-R2 and -R1, a mixture of 25-hydroxy-20(S)-ginsenoside-Rh1 and its C-20 (R) epimer, ginsenoside-Rh4. The complete assignments of the H-1 and C-13 NMR chemical shifts for these glycosides were obtained by means of 2D NMR techniques, including H-1-H-1 COSY, ROESY, HMQC, HMBC and HMQC-TOCSY spectra. The glycosylation shift effect of protopanaxatriol and the differences in chemical shifts between 20(R)- and 20(S)-protopanaxatriol isomers are also discussed. Except for ginsenoside-Re and -Rg2, complete NMR assignments of the other seven glycosides are reported for the first time. Copyright (C) 2002 John Wiley Sons, Ltd.
