摘　　要：Polygala multiflora Poiret is an oleaginous plant in Burkina Faso, but most of its quality characteristics remain unexplored. This work aimed to evaluate the chemical and sensory quality of Polygala multiflora Poiret crude oil. Chemical parameters were determined using AOAC standards. The sensory analysis of the samples was carried out using three tests (descriptive and hedonic classification). Principal component analysis (PCA) was used to establish the relationship between the panelists’ evaluation of the attributes and the type of oil extracted. The results showed that P. multiflora seed oil is mainly produced by women using a mechanical extraction process. The chemical analysis of the extracted oil showed a refractive index (1.45 ± 0.02), free fatty acids (1.97% ± 0.2% ac. oleic), acidity index (6.93 ± 0.14 mg KOH/g), saponification index (186.3 ± 9.31 mg KOH/g), iodine index (40.37 ± 0.5 gI2/100 g) and peroxide index (1.58 ± 0.05 Meq O2/kg). The descriptive sensory attributes showed that the crushed seed oil had the highest appreciation percentage value. The hedonic test showed that the highest percentage value of the attribute “like it” was associated with whole seed oil. The results of the Principal Component Analysis (PCA) showed the variability of the sensory quality depending on the type of oil extracted.Polygala multiflora Poiret is an oleaginous plant in Burkina Faso, but most of its quality characteristics remain unexplored.
