Momordica charantia
(NCBI TaxID 3673,
species name lookup)
Taxonomic group: plant / Streptophyta
(Phylum: Streptophyta)
The structure was elucidated in this paperJournal NLM ID: 0377775WWW link: http://ci.nii.ac.jp/naid/110003624094Publisher: Pharmaceutical Society Of Japan
Institutions: Faculty of Pharmaceutical Sciences, Fukuoka University, Japan, Faculty of Pharmaceutical Sciences, Kyushu University, Japan
Two triterpene glycosides, momordicosides A and B, were isolated from the seeds of Momordica charantia L. (Cucurbitaceae). Their structures were determined on the basis of spectral and chemical evidence and by X-ray analysis as the 3-O-β-gentiobioside and 3-O-β-D-xylopyranosyl(1→4)-[β-D-glucopyranosyl(1→6)]-β-D-glucopyranoside, respectively, of cucurbit-5-ene-3β,22(S),23(R),24(R),25-pentaol.
