Abstract
|
|
|
|
One new sterol glucoside, gomphsterol β-D-glucoside 1 along with known compounds, β-sitosterol, stigmasterol, campesterol, stigmasterol-β-D-glucoside, friedelin, 3-epi-friedelinol, allantoin, and chrysoeriol-7-O-β-D-glucoside have been isolated from the aerial parts of Gomphrena globosa (Amaranthaceae). On the basis of spectroscopic (including 2D NMR) and chemical studies, the structure of 1 was elucidated as (22E, 24S)-24-ethylcholesta-7,9(11), 22-trien-3β-ol-3-β-D-glucopyranoside. Known compounds are reported for the first time from this plant species.
