Isolation of 8-hydroxyglycitein and 6-hydroxydaidzein from soybean miso.

چکیده
We isolated from soybean miso 8-hydroxyglycitein and 6-hydroxydaidzein as DPPH-radical scavengers, and elucidated their chemical structures by mass spectrometric, and (1)H- and (13)C-NMR spectrosopic analyses. These compounds showed DPPH-radical scavenging activity as high as that of alpha-tocopherol, 8-hydroxygenistein and 8-hydroxydaidzein. This is the first report of the isolation of 8-hydroxyglycitein from a natural source.

متن کاملDPPH radical-scavenging compounds from dou-chi, a soybean fermented food.
Dou-chi, a traditional soybean food fermented with Aspergillus sp., is usually used as a seasoning in Chinese food, and has also been used as a folk medicine in China and Taiwan. As 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical-scavengers, four phenol compounds, one isoflavanone, eight isoflavones and one 4-pyrone have been isolated from dou-chi. Among these fourteen compounds, 3'-hydroxydaidzei...

The aldose reductase (AR) inhibitor, 8-hydroxydaidzein, was isolated and identified from a methanolic extract of okara (soybean pulp) fermented with the fungal strain, Aspergillus sp. HK-388. 8-Hydroxydaidzein showed non-competitive inhibition of human recombinant AR with respect to DL-glyceraldehyde, its Ki value being evaluated as 7.0 microM.
متن کاملHypoallergenicity of various miso pastes manufactured in Japan.
Miso paste (miso), a fermented soybean food, is popular in Japan and other Asian countries. However, the soybean is known to induce an allergenic response in some individuals. In the present study, we evaluated the allergenicity of various kinds of miso available in Japan. Total proteins were extracted from Amakuti-kome miso, Karakuti-kome miso, Mugi-miso and Mame-miso, and the protein profiles...

The formation mechanism for the potent antioxidative o-dihydroxyisoflavones, 8-hydroxydaidzein (8-OHD) and 8-hydroxygenistein (8-OHG), was studied by incubating whole soybeans in a solid culture and a soybean extract in a liquid culture with Aspergillus saitoi. Analyses of changes in the isoflavone analogue content, β-glucosidase activity, and isoflavone hydroxylation ability indicated that 8-O...
