  abstract = {{C}owpea is a legume, rich in protein, {B} vitamins and minerals (magnesium, zinc), but also rich in antinutritional factors such as alpha-galactosides and phytic acid. {T}he nutritional composition of cowpea seeds


is therefore a criterion that should be taken into account to improve varietal selection. {T}he nutritional composition of 13 varieties of cowpea cultivated in {B}urkina {F}aso was characterised in


order to identify varietal selection criteria based on nutritional potential. {N}ine varieties were cultivated in {T}enkodogo ({T}), 10 in {K}amboins{\'e} ({K}), and 6 in both localities. {P}rotein content were determined by the


{K}jeldahl method, mineral content by {ICP}-{OES}, thiamine content by {UHPLC}-{FLR}, phytic acid content by {HPAEC}-{CD} and alpha-galactosides and low-molecular-weight sugars content were quantified by {HPAECPAD}.


{V}ariance analysis allowed to evaluate the effect of variety using results obtained in each site (n{T}=9, and n{K}= 10), as well as effect of locality using results from varieties cultivated in both sites.


{T}he protein contents of the samples studied vary between 19,9 and 26,2 g/100 g {DM} depending on the variety. {T}he phytate content was higher on the {K}amboins{\'e} plot (with results ranging from 0,70 to 1,17 g


{IP}6/100 g {DM}) than on the {T}enkodogo plot (0,42 to 0,80 g {IP}6/100 g {DM}). {T}hiamine equivalent contents, ranging from 0,34 to 0,73 mg/100 g {DM}, showed a significant variety and plot effect. {T}he main forms of


thiamine (di-phosphate and hydrochloride thiamins) were present in variable proportions depending on the variety and the plot. {I}ron and zinc content were mainly affected by variety and varied between 3,70 to


5,92 mg/100 g {DM} and from 3,30 to 5,14 mg/100 g {DM} respectively. {T}he total ?-galactoside content was between 3,27 and 6,09 g/100 g {DM}, and the sucrose content ranged from 1,29 to 5,80 g/100 g {DM}, both


influenced by variety. {A}ll components were also influenced by the interaction between variety and plot. {R}esults of nutritional composition should be related to agriculture and processing practices to identify


processes decreasing antinutritional factors (alpha-galactosides, phytic acid) while taking account consumers preferences. {P}hyate, iron, zinc, thiamin, alpha-galactoside contents could constitute additional criteria in


varietal selection of cowpea, in {B}urkina {F}aso.},
