  • Spectroscopic analyses including UV, 1H and 13C NMR, NOE difference measurements, and mass spectrometry (D/CI and FAB-MS).

    • Main Results:

    • A new kaempferol triglycoside, kaempferol 3-O-beta-D-glucosyl-(1----2)-O-[alpha-L-rhamnosyl(1----6)]-beta-D-galactoside, was identified.
    • Three known kaempferol glycosides, including two apiosides, were isolated and characterized.
    • The configuration of the apiosyl moiety in specific galactosides was determined using NOE difference measurements on peracetate derivatives.

    Conclusions:

    • The study successfully identified and characterized a novel kaempferol triglycoside from Monnina sylvatica.
    • The findings expand the repertoire of known kaempferol glycosides and provide detailed structural information.
    • This research enhances the understanding of the chemical constituents of Monnina sylvatica and contributes to natural product chemistry.
