“…However, for TW variety, other than three major anthocyanins (peaks 1, 3 and 4) which represented about 93% of the total peak area (Table 1), four unidentified minor peaks (2, 5, 6 and 7) were detected. The three major anthocyanins in black soybean seed coats, D3G, C3G and Pt3G, were previously identified by Kuroda and Wada (1933), Yoshikura and Hamaguchi (1969), Choung et al (2001) and Lee et al (2009).…”

“…Although an extensive scientific literature on the composition of anthocyanins in fruits and vegetables exists (Francis 2000;Mazza and Gao 2005), reports on anthocyanins in different varieties of black soybean are limited with controversial results. Several groups (Choung et al 2001;Kuroda and Wada 1933;Yoshida et al 1996;Yoshikura and Hamaguchi 1969) have identified only one to three different anthocyanins [cyanidin-3-O-β-D-glucoside (C3G), delphinidin-3-O-β-D-glucoside (D3G) and petunidin-3-O-β-D-glucoside (Pt3G)], while Lee et al (2009) recently reported nine different anthocyanins, which included three major anthocyanins and several other anthocyanins. These studies show substantial differences in anthocyanin contents and compositions among varieties.…”

Anthocyanin pigments in black soybean (Glycine max (L.) Merr.) varieties as Tawonkong (TW) and Geomjeongkong-2 (G2) were identified to evaluate their potentials as nutritional function, natural colorant or functional foods. Anthocyanin extraction was conducted with acidified methanol with 0.1 M HCl (85:15, v/v). Identification of anthocyanin was conducted by comparison with purified standards by HPLC and mass spectrometry (MS). G2 showed six different types of pigments by HPLC, whereas TW showed seven pigments. Three major anthocyanins (peaks 1, 3, 4) were detected in both varieties and peak 1 was characterized as delphinidin-3-O-β-D-glucoside, peak 3 as cyanidin-3-O-β-D-glucoside (C3G), and peak 4 as petunidin-3-O-β-D-glucoside by comparison of chromatographic properties with authentic standards and MS. Minor peaks 5, 6 and 7 in TW were tentatively identified as pelargonidin-3-Oglucoside, pelargonidin-3-O-(6″-malonylglucoside) and cyanidin on the basis of MS. MS with major ions at 287 and 449 of peak 2 were exactly same as those of peak 3 meaning that peak 2 has cyanidin and other hexose different from glucose. After acid hydrolysis of fractioned peak 2, HPLC showed the hexose as galactose, and peak 2 was identified as C3Glactose.The most abundant anthocyanin in black soybean (Glycine max (L.) Merr.) was C3G and G2 showed the higher amount of total anthocyanins than TW (p<0.001).

“…In this study, we analysed the altered anthocyanin content in the four soybean mutant lines generated by gamma ray mutagenesis using UHPLC. The major anthocyanin of black soybean seed coats was cyanidin-3-glucoside, and delphinidin-3-glucoside and pelargonidin-3-glucoside were identified in the black-seeded variety and the reddish-buff seed coat of T236 soybeans (Kuroda and Wada 1933, Yoshikura and Hamaguchi 1969, Taylor 1976). Choung et al (2001) reported that 10 black soybean varieties showed different compositions of C3G, D3G and Pt3G, and their content ranged from 1.58 to 20.18 mg/g.…”

In this study, the flavonoid and isoflavone contents in four checks with seed coat colour altered from yellow to black were determined, and their antioxidant activity was measured. Three anthocyanins (delphinidin-3-Ob-D-glucoside, D3G; cyanidin-3-O-b-D-glucoside, C3G; and petunidin-3-O-b-D-glucoside, Pt3G) were detected in the four checks, while their controls (cvs. 'Danbaek' and 'Daepung') were not found. Among them, D-16 derived from cv. 'Danbaek' showed the highest anthocyanin contents. The isoflavone contents of all checks showed lower levels compared to their controls. Among six isoflavones, glycitein was only detected in DP-39. To analyse the radical scavenging activities among the four checks, we conducted DPPH, FRAP and UWLA assays. Significant differences in antioxidant activities were obtainable in the four checks, which contained significant differences in levels of anthocyanins and isoflavones. Based on these results, gamma irradiation may change the isoflavone and anthocyanin contents of soybean. Our four checks selected in this study may be useful for breeding soybean varieties to alter their nutritional values.
