Six triterpenoid saponins, including one new compound, quinquenoside F-6 (1), and five known compounds ginsenoside Re(2), ginsenoside Rg(1)(3), ginsenoside Rg(2)(4), ginsenoside Rh-1(5) and pseudo-ginsenoside F-11(6), were isolated from the fruits of Panax quinquefolium L., and the structure of compound 1 was elucidated as 6-O-beta-d-glucopyranosyl-20-O-[alpha-l-arabino- furanosyl-(1-6)-beta-d-glucopyranosyl]-dammar-24-ene-3 beta, 6 alpha, 12 beta, 20S-tetraol by the combination of the analysis of spectroscopic data and chemical evidences. The complete signal assignments of the six compounds were carried out by means of 2D NMR spectral analysis.
