“…8 Detailed comparison of the 13 C-NMR spectrum of 1 with that of molihuaside A revealed that both substances possess the same basic skeleton. 11 Although the HMBC spectrum (Fig-ure 1) did not show any correlation between C-7′ (δ 172.9) and H-5′′ due to the low sensitivity of H-5′′ (δ 5.04, dd, J ) 3.9, 6.6 Hz), a diagnostic correlation (δ 173.4, δ 3.96) established a structural linkage between C-7 and H-7′′. In addition, the carbon signals at δ 41.8 (C-1′′) and 80.0 (C-5′′) of 1 were different from those in molihuaside A, which showed corresponding signals at δ 44.…”

Mass spectrometry is essential for the structure determination of naturally occurring glycosides. Molecular weight and sugar sequence information can be obtained. Development of “soft” ionization techniques has allowed a direct mass spectrometric investigation of underivatized glycosides. Numerous different and complementary methods of ionization have been used for their study. For a given compound, the choice of a particular technique is crucial in order to obtain the structural information needed. A brief survey of these ionization techniques is given, together with examples of their use in major classes of plant glycosides.

“…The 1H-NMR spectrum of 3 showed three sets of signals for bO-hydroxyoleoside-il-methyl ester (7) as well as signals for a p-hydroxyphenethoxy moiety. Its 13C-NMR spectrum ( Table 2) revealed resonances of 59 carbons, 42 of which were in excellent agreement to those of jasamplexoside A (2). The chemical shifts of the remaining 17 carbons were closely similar to those of the inner lO-hydroxyoleoside-11-methyl ester unit of 2.…”
