“…Xu and Chang [8] reported a lot of differences in the phenolic acid profile and flavan-3-ol composition of lentils, which are probably attributable to a number of factors, such as phenotype, crop location, and environmental stress. Other studies have reported changes in tannin content that depend on the color of the seed coat, as legumes with a dark seed coat have large amounts of phenolic compounds, especially for the anthocyanins and condensed tannin [45,46]. Also, Xu et al [44] determined a correlation between phenolic compounds and color value across five types of legume, whereby species with a colored seed coat have higher TPC, TFC and CTC, in comparison to species with paler colored seed coats; within species with colored seed coats (i.e., lentils and colored beans), there is a different phenolic composition in relation to the color variation.…”

A two year field experiment was carried out to evaluate the effects of three row and eight row seeding on the total phenolic compound (TPC), total flavonoid content (TFC), hydrolyzed (HTC) and condensed tannin (CTC), antioxidant activity (ABTS assay), protein content and soluble dietary fiber (SDF) and insoluble dietary fiber (IDF) in the extracts of lentil (Lens culinaris L.) and grass pea (Lathyrus communis L.) cultivated under organic farming. The aim of this study was to determine whether row spacing used for seeding in organic farming systems for lentil and grass pea is a suitable method to increase the accumulation of antioxidant compounds in these crops. Grass pea showed the highest mean SDF and protein while lentil varieties showed the greatest and significant content of all of the antioxidant compounds. In lentil, there were increases in TPC (52%), HTC (73%), TFC (85%) and CTC (41%), passing from three rows to eight rows, while in grass pea, the increases were lower, and only significant for TFC and CTC (37%, 13% respectively). In both lentils and grass pea, the highest correlation coefficient was between TPC and HTC, which indicates that the HTC includes the predominant phenolic compounds in lentil as well as in grass pea (r = 0.98, 0.71 p < 0.001, respectively). Regardless of legume species, TPC, HTC, TFC and CTC showed significant (p < 0.001) and linear correlations with the ABTS assay. These data confirm the key role of row spacing for the improvement OPEN ACCESSSustainability 2014, 6 1060 of the antioxidant properties of lentil in organic farming; moreover, they hint at the major responsiveness and adaptation of lentil to environmental stimulus with respect to grass pea.

“…Literature data rarely report on equally high values except to Naczk et al [32], who noted 1,694 A 500 units/g of beach pea tannin fraction, and Arfan et al [33], who found 1,321 A 500 units/g of Mallotus philippinensis bark tannin fraction. Condensed tannins were previously reported as predominant compounds of other legume seeds coats such as common bean seed [34], soybean seed [30], and lentil seed [21].…”

The binding of tannin fraction to protein fractions isolated from broad bean seeds was studied by precipitating potential and fluorescence quenching methods. The tannin fraction with high proanthocyanidins content was isolated from broad bean coats. Storage proteins of broad bean, 11S, 7S, and 2S, were isolated from broad bean cotyledons and purified. Gelatin, BSA, as well as broad bean 2S and 7S protein fractions exhibited similar shape of curves illustrating the effect of pH on protein precipitation and were precipitated by broad bean tannin fraction over the wide range of pH. For pea proteins isolate and 11S fraction of broad bean proteins, quite different effect of pH was observed. The relationships between the amount of proteinpolyphenols complex precipitated and the content of tannin fraction were linear and characterized by high squared correlation coefficients ranging from 0.9613 to 0.9938. Among the protein fractions isolated from broad bean seeds, the highest precipitating potential was noted for 11S fraction, followed by 7S and 2S fractions and amounted to 1.63, 1.34, and 0.87, respectively. To characterize the association of proteins with phenolic compounds yielding formation of soluble complexes, fluorescence spectroscopy was applied. Similarly, the most extensive fluorescence quenching was observed in the case of 11S protein fraction.

“…The column was successively eluted with ethanol, methanol, and 60% acetone, to collect fractions I (fra.I), fraction II (fra.II), and fraction III (fra.III), respectively. The proanthocyanidin content of each fraction was determined by the HCl-butanol method [13], using cyanidin as the standard equivalent.…”

Proanthocyanidins are oligomeric or polymeric flavonoids found in several plants. They can be classified into two subgroups, namely A-and B-type proanthocyanidins. The coat of scarlet runner beans contains abundant proanthocyanidins (SRPAs) of the B-type configuration. To evaluate the efficacy of SRPAs as anti-obesity agents, we first examined their effect on lipase activity in vitro and found that they are potent inhibitors of this enzyme. Subsequently, we examined their effect on mice fed a high-fat diet. Male mice were assigned to the following seven-subject dietary groups: (1) high-fat diet; (2) high-fat diet supplemented with 0.5% SRPAs; (3) high-fat diet supplemented with 1.0% SRPAs, and; (4) standard chow for 15 weeks. SRPA supplementation decreased body weight gain; liver and kidney weight; perirenal, peritesticular, and periintestinal fat content; liver cholesterol level, and; serum neutral lipid and cholesterol levels. In contrast, the faecal lipid content and the liver anti-oxidative capacity increased. These findings suggest a potential use of SRPAs as a dietary supplement exerting anti-obesity effects through the inhibition of fat digestive enzymes.
