摘要：

A new kaempferol triglycoside and three known kaempferol glycosides, among them two apiosides, have been isolated from the aerial parts of Monnina sylvatica. The structures were established on the basis of acid and enzymatic hydrolysis and spectral data (UV, H-1 and C-13 NMR, NOE difference measurements, D/CI and FAB-MS) of the isolates and of some derivatives. The triglycoside kaempferol 3-O-beta-D-glucosyl-(1 --> 2)-O-[alpha-L-rhamnosyl(1 -->6)]-beta-D-galactoside is a new natural product. The configuration of the apiosyl moiety in kaempferol 3-O-beta-D-apiosyl(1 --> 2)-beta-D-galactoside and kaempferol 3-O-beta-D-apiosyl(1 --> 2)-O-[alpha-L-rhamnosyl(1 --> 6)]-beta-D-galactoside was established through NOE difference measurements on the peracetate.
