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 β-amyrin acetate, β-sitosterol acetate, 22-cyclohexyl-1-docosanol, β-amyrin, β-sitosterol, and β-sitosterol 3-O-β-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.
