Alliumonoate: a new cyclopentane derivative from Allium victorialis.

Alliumonoate, a new cyclopentane derivative, has been isolated from the chloroform-soluble fraction of the ethanolic extract of Allium victorialis, along with ß-amyrin acetate, ß-sitosterol acetate, 22-cyclohexyl-1-docosanol, ß-amyrin, ß-sitosterol, and ß-sitosterol 3-O-ß-D-glucopyranoside, reported for the first time from this species. Their structures were elucidated on the basis of spectral data including mass spectra and 2D NMR experiments.
