    • The structure of 6 was known;8 the genin of 6 is phytolaccagenin with the known absolute configuration and sugar moiety of 6 consisting of D-xylose and D-glucose. Considering the biosynthesis of an oleanane-type triterpene in the same plant, the absolute configuration of genin moieties of 1, 2, and 6 is the same. The only difference in their structures is the substituent at C-11. In a comparison of13C NMR spectra, δC values of C-2, C-3, C-4, C-1′ C-2′, and C-3′ in compounds 1 and 2 were exactly the same as those of 6. If the sugar moiety at C-3 of 1 and 2 is L-xylose instead of D-xylose, they will show different δC values. The same explanation is possible for δC values around the glucopyranosyl bond at C-4′ of xylopyranose and the glucopyranosyl bond at C-28. Since compounds 1 an
    • D values, we deduced the same absolute structure for 1 and 2 as 6.
