“…In fact, our findings are associated with the previous results, in which black soybeans showed the highest in vitro ACE inhibitory activity than black turtle beans and lentils [ 47 ]. Similarly, adzuki bean extracts showed in vitro ACE inhibitory activity, similar to captopril (0.25 µg/mL) [ 48 ]. As a source of such functionality of black soybean extracts and adzuki bean extracts, flavonoids, alkaloids, and tannins in extracts play a role in hydrogen bonding at the active site of ACE as a competitive inhibitor, form chelate complexes with the zinc, or precipitate protein [ 49 , 50 ].…”

Hypertension, causing cardiovascular disease, stroke, and heart failure, has been a rising health issue worldwide. Black soybeans and adzuki beans have been widely consumed throughout history due to various bioactive components. We evaluated the antihypertensive effects of black soybean and adzuki bean ethanol extracts on blood pressure, renin-angiotensin system (RAS), and aortic lesion in spontaneously hypertensive rats. A group of WKY (normal) and six groups of spontaneously hypertensive rats were administered with saline (SHR), 50 mg/kg of captopril (CAP), 250 and 500 mg/kg of black soybean extracts (BE250 and BE500), 250 and 500 mg/kg of adzuki bean extracts (AE250 and AE500) for eight weeks. BE250, BE500, AE250, and AE500 significantly (p < 0.05) reduced relative liver weight, AST, ALT, triglyceride, total cholesterol, systolic blood pressure, and angiotensin-converting-enzyme level compared to SHR. The angiotensin II level in AE500 and renin mRNA expression in BE500 and AE500 were significantly (p < 0.05) decreased compared to SHR. The lumen diameter was significantly (p < 0.05) reduced in only CAP. Furthermore, systolic and diastolic blood pressure and angiotensin II level in AE500 were lower than those of BE500. These results suggest that AE exhibit more antihypertensive potential than BE in spontaneously hypertensive rats.

This study investigated the functional compounds and physiological activities of proso millet (PM) cultivars to select a good cultivar for use in the food processing and cosmetic industries. The total dietary fiber content of PM cultivar Manhongchal (6.65%) was higher than other cultivars. The total polyphenol content of Hwangsirchal was 7.67 mg/g extract, which was higher than that of other cultivars, and the phytic acid content of Hwanggum was the highest at 1.20 g/100 g. DPPH radical scavenging activity was higher in Hwangsilchal, Ebaekchal, Hwanggum, and Hallachal compared to the other cultivars. Hallachal and Hwangsirchal showed higher ABTS radical scavenging activity than other cultivars, and the ferric reducing ability of plasma (FRAP) value of Manhongchal was the highest at 97.48 mM. The cultivars Ebaekchal, Hwangsirchal, and Manhongchal showed more than 95% α-glucosidase inhibitory activity. The angiotensin converting enzyme and tyrosinase inhibitory activities of PM cultivars Manhongchal (27%) and Ollechal (56.72%) were higher than other cultivars. To summarize, Hwangsirchal, Manhongchal, and Ollechal could be highly useful as food and cosmetic materials.

This study was undertaken to investigate the physicochemical characteristics, functional compounds, and physiological activities of adzuki bean cultivars. The crude lipid and protein contents showed a significant difference between AB cultivars, ranging from 0.30∼0.76% and 21.54∼24.09%, respectively. Starch and amylose contents were determined to range between 46.77∼51.51% and 15.67∼18.24%, respectively, and were relatively lower in 'Yeonduchae' than in other cultivars. Breakdown, which is an index of superior taste, was highest in 'Seona' and 'Yeonduchae', whereas setback, which is an index of retrogradation property, was lower in 'Geomguseul' and 'Yeonduchae' than in other cultivars. The water binding capacity and solubility were determined to be 116.86∼188.22% and 24.72∼27.44%, respectively, and were significantly higher in 'Yeonduchae' than in other cultivars. Insoluble and soluble dietary fiber contents showed a significant difference between the cultivars, ranging from 6.59∼8.63% and 0.24∼0.91%, respectively; both contents were relatively higher in 'Geomguseul'. Total polyphenol content was highest in 'Huinguseul' (15.53 mg GAE/g), and phytic acid levels were highest in 'Chungjupat' and 'Seona' (1.08 and 1.05 g/100 g, respectively). Antioxidant activity was relatively higher in 'Huinguseul' and 'Hongeon' and lower in 'Huinnarae' and 'Arari' as compared to other cultivars. α-Glucosinase and tyrosinase inhibition activities were significantly higher in 'Huinguseul' (29.30%) and 'Geomguseul' (57.77%). The present study provides basic information on the functional properties of adzuki bean cultivars, and will aid the utilization of adzuki bean as a material for food processing and in the cosmetic industry.
