“…Anthocyanins are normally present as glycosides in plants, and anthocyanin-flavanol derivatives found in pomegranate juice are also glycosides [22]. Cyanidin-3-O-glucoside, pelargonidin-3-O-glucoside, and malvidin derivate were also detected in kidney bean seeds [23]. We could not find anthocyanin in the other two common beans by HPLC-PDA/MS.…”

The pods of common beans (Phaseolus vulgaris) are rich in various nutrients, and they could therefore be important parts of the human diet. In the present study, we have analyzed the 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity and the contents of polyphenols, anthocyanin, vitamin C, and carotenoid in the pods of 3 varieties of common beans. French beans had the highest DPPH radical scavenging activity and polyphenol contents among the three varieties. The anthocyanin content was 3.93 mg/g D.W. in French beans, but not detected in bush beans and Romano beans. The vitamin C and carotenoid contents ranged from 0.45-1.96 and 0.31-0.60 mg/g D.W. in the pods of these common beans, respectively. Moreover, we found French beans contained monomeric (Fra.I), oligomeric (Fra.II), and polymeric (Fra.III) polyphenols (67%, 31%, and 2%, respectively). In contrast, monomeric polyphenols are the main polyphenols (Fra.I > 96%) in bush beans and Romano beans. Oligomeric polyphenols (Fra.II) show higher DPPH radical scavenging activity than monomeric ones (Fra.I) in French beans. Oligomeric polyphenols with both B-type and A-type bonds were present in Fra.II from French beans. We identified malvidin 3,5-diglucoside as the anthocyanin in French beans by HPLC-PDA/MS. In summary, as a vegetable, French beans have the highest antioxidant activity among the three varieties of common bean pods studied here.

“…There are some studies reporting that germination is an efficient process to increase the TPC of beans (Randhir et al 2004;Fernandz-Orozco et al 2006;Fernandz-Orozco et al 2008;DueÑas et al 2015). The changes of TPC are presented in Figure 3D.…”

Xue Z., Wang C., Zhai L., Yu W., Chang H., Kou X., Zhou F. (2016): Bioactive compounds and antioxidant activity of mung bean (Vigna radiata L.), soybean (Glycine max L.) and black bean (Phaseolus vulgaris L.) during the germination process. Czech J. Food Sci., 34: 68-78.Bioactive compounds and antioxidant activity of germinated mung bean, soybean and black bean sprouts were investigated to find out the effect of germination and the optimum germination time. We found that vitamin C gradually increased from zero. Compared to seeds, water-soluble protein and total flavonoid content showed a trend of sustained growth while vitamin E, total phenolic content increased at first and then decreased, the maximal value of total bioactive compound content was reached on the fifth day. The analysis of relative contribution revealed that total phenolics and total flavonoids made the highest (44.87-90.31%) contribution to total antioxidant activity. In conclusion, the optimum germination time for sprouts was 3-5 days when total bioactive compound content and antioxidant activities both reached their peak values, which provide a sufficient theoretical basis for dietary processing and lay a solid foundation for continued research.

“…It can be hypothesized that glutamic acid could participate in the formation of some antioxidant compounds to maintain a balance of the redox homeostasis during germination. Additionally, glutamic acid might change the phenolic composition in sprouted lentils, increasing the content of those compounds with higher radical scavenging activity, as it has been previously showed in kidney beans [34].…”

The aim of this study was to investigate the application of elicitors (500 μM ascorbic acid, 50 μM folic acid, 5 mM glutamic acid and 50 ppm chitosan in 5 mM glutamic acid) during lentil germination up to 8 days as a strategy to increase germination rate and to enhance the accumulation of γ-aminobutyric acid (GABA) and phenolic compounds. The effect of elicitation on the protein profile and antioxidant and angiotensin I converting enzyme (ACE) inhibitory activities of sprouted lentils was also evaluated. The application of elicitors did not negatively affect the germination yield of lentils and no significant changes on the protein pattern of lentils germinated in the presence of elicitors were observed. Chitosan/glutamic acid increased by 1.6-fold the GABA content in lentil sprouts, whilst ascorbic and folic acids as well as chitosan/glutamic acid were highly effective to enhance the total content of phenolic compounds and the antioxidant activity of sprouted lentils. All elicited lentil sprouts showed ability to inhibit ACE activity (IC50: 9.5-11.9 μg peptides/mL). Therefore, elicitation can be considered a promising approach to improve the content of compounds with antioxidant and potential antihypertensive activities in lentil sprouts.
