ABSTRACT


Abstract: Black turtle bean is a variety of Phaseolus vulgaris L. in the legume family Fabaceae and is consumed as food worldwide. A targeted phytochemical investigation of the ethanolic extract of its seeds, focusing on constituents other than the lipophilic metabolites, resulted in the isolation and characterization of five compounds (1-5). Compound 1 (phasvulic acid), a previously undescribed cyclohexane carboxylic acid derivative, was characterized as (Z)-3-hydroxy-2-(5-hydroxypent-2-en-1-yl)cyclohexane-1-carboxylic acid based on spectral data including 1D and 2D NMR (1H, 13C, COSY, HSQC, and HMBC) and high-resolution electrospray ionization mass spectrometry (HR-ESI-MS). Other compounds were formerly described as dihydrophaseic acid (2), uridine (3), stigmasterol-3-O-β-D glucopyranoside (4), and β-sitosterol-3-O-β-D-glucopyranoside (5).
