Article Description

Two triterpenoidal saponins were isolated from the seeds of Momordica cochinchinensis Sprenger (Cucurbitaceae). Identification of chemical structures has been performed by H- and C-NMR spectroscopy and gas chromatography (GC). One of the saponins is a new gypsogenin glycoside, named as gypsogenin 3-O-β-D-galactopyranosyl(1→2)-[α-L- rhamnopyranosyl(1→3)]-β-D-glucuronopyranoside (compound 1), which is reported for the first time from natural resources. The other saponin is a quillaic acid glycoside (compound 2), which showed anti-inflammatory activities in RAW 264.7 cells. The mechanistic understanding of anti-inflammatory activities demonstrates that compound 2 inhibits lipopolysaccharide-induced expression of nitric oxide and IL-6 via NF-κB pathway. © 2012 Informa Healthcare USA, Inc.
