Abstract： Objective To carry out a systematic study on the chemical constituents in the fruits of Momordica grosvenori. Methods To isolate pure compounds by using repeated column chromatography,while the structure of a new compound was determined by detailed spectral analysis. Results Four cucurbitane triterpenoid glycosides, mogroside Ⅱ E (Ⅰ), mogroside Ⅲ (Ⅱ), grosmomoside Ⅰ (Ⅲ), and mogroside Ⅴ (Ⅳ) were isolated from the 50% ethanolic extract of the fruits of M. grosvenori. Conclusion Grosmomoside Ⅰ is a new compound identified as mogrol-3-O-β-D-glucopyranoside-24-O-{[β-D-glucopyranosyl (2-1 ) ]- [β-D-glucopyranosyl (6-1 ) ]-β-D-galactopyranoside } and the other three compounds are known compounds.
