Methods These compounds were separated and purified by column chromatography, and their structures were elucidated based on spectroscopic analyses (HR-ESI-MS, ESI-MS, 1H-NMR, 13C-NMR, HSQC and HMBC). Results Eighteen compounds were obtained from the acid hydrolysates of PNS and characterized as dammar-25-ene-24-hydroperoxyl-3β,6α,12β,20S-tetraol (1), 6α,12β,20S-trihydroxy-dammarane-24-ene-3-O-β-D-glucopyranosyl-(1→2)-β-D-glucopyranoside (2), 6α,12β,20R-trihydroxy-dammarane-24-ene-3-O-β-D-glucopyranosyl-(1→2)-β-D-glucopyranoside (3), vina-ginsenoside-R8 (4), 24(S)-pseudo-ginsenoside-GQ (5), ginsenoside Rg5 (6), 20 (R)-ginsenoside Rg3 (7), 20(R)-ginsenoside Rk2 (8), 3β,12β-dihydroxy-dammar-(E)-20(22),24-diene-6-O-β-D-xylopyranosyl-(1→2)-β-D-glucopyranoside (9), 20(S)-ginsenoside Rg2 (10), ginsenoside SL1 (11), 20(R)-ginsenoside Rh1 (12), 20(22) E-ginsenoside Rh4 (13), 25-hydroxy-20(R) ginsenoside-Rh1 (14),3β,6α,12β,20(S)-20,25-epoxy-3,12-dihydroxy-dammarane-6-O-β-D-glucopyranoside (15), 20(R)-protopanaxadiol (16), 20(R)-protopanaxatriol (17), and 20(S)-protopanaxatriol (18). Conclusion Compound 1 is a new triterpen saponin, and compounds 2-5 are isolated from P. notoginseng and acid dydrolysates of PNS for the first time."/>
