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.

Foenumoside B (FSB), a bioactive component isolated from the Lysimachia foenum-graecum extract (LFE), has been shown to possess anti-inflammatory effects, but the underlying molecular mechanisms involved have not been elucidated. Accordingly, the authors investigated the mechanisms responsible for the anti-inflammatory effects of FSB in murine macrophages activated by LPS. FSB suppressed the LPS-induced expressions of iNOS and COX-2 at protein and mRNA levels and consequently decreased NO and PGE2 production in RAW264.

Eleven oleanane-type triterpenoid saponins, foegraecumosides A-K, and eight known ones, were isolated from the aerial parts of Lysimachia foenum-graecum. Their structures were elucidated by spectroscopic data analyses and chemical methods. All isolated saponins were evaluated for their cytotoxicity against four human cancer cell lines (NCI-H460, MGC-803, HepG2, and T24).

Lysimachia foenum-graecum extract (LFE) and its active component foenumoside B (FSB) have been shown to inhibit adipocyte differentiation, but their mechanisms were poorly defined. Here, we investigated the molecular mechanisms responsible for their anti-adipogenic effects. Both LFE and FSB inhibited the differentiation of 3T3-L1 preadipocytes induced by peroxisome proliferator-activated receptor-γ (PPARγ) agonists, accompanied by reductions in the expressions of the lipogenic genes aP2, CD36, and FAS.
