title: Two new triterpenes from Lysimachia foenum-graecum.
abstract: Two new oleane-type triterpene saponins, lysimachiagenoside E (1) and lysimachiagenoside F (2), were isolated from the aerial parts of Lysimachia foenum-graecum Hance. The structures were elucidated on the basis of 1D and 2D NMR techniques, including (1)H-(1)H COSY, HMQC, HMBC, TOCSY, ROESY experiments as well as chemical methods.
