kaempferol/ダイズ

We have recently purified genistin, and six kaempferol glycosides from a soy leaves ( Glycine max L. Merr.) butanol extract. Here we report the vascular effects of the extract and purified genistin and kaempferol glycosides on contractions induced by different constricting agonists in isolated rat

The anti-diabetic effects of a kaempferol glycoside-rich fraction (KG) prepared from leaves of unripe Jindai soybean (Edamame) and kaempferol, an aglycone of kaempferol glycoside, were determined in genetically type 2 diabetic KK-A(y) mice. The hemoglobin A(₁c) level was decreased and tended to be

The study investigated the protective effects of kaempferol galactoside (KG) components in mice, which were separated from Jindai soybean leaves (JDL) and mainly composed by two kaempferol galactosides. Further, KG-related metabolites in serum of mice were identified by Tof-MS. Results showed that

Soybean (Glycine max L.) strains which accumulate kaempferol 3-(2(G)-glucosylgentiobioside) in their leaves fix CO(2) at rates significantly lower than those lacking this compound (Buttery, Buzzell 1976 Crop Sci 16: 547-550), and kaempferol aglycone is a well known inhibitor of photosynthesis in

A glucosyltransferase, which catalyses the glucosylation of flavonols, using uridine diphosphate-D-glucose as glucose donor, has been isolated and purified about 5-10 fold from cell suspension cultures of soybean (Glycine max L., var. Mandarin). The pH optimum for this reaction was ca. 8.5 in

Atmospheric levels of carbon dioxide (CO2) have been increasing steadily over the last century. Plants grown under elevated CO2 conditions experience physiological changes, particularly in phytochemical content, that can influence their suitability as food for insects. Flavonoids are important plant

Flavonoids, natural products abundant in the model legume Glycine max, confer benefits to plants and to animal health. Flavonoids are present in soybean mainly as glycoconjugates. However, the mechanisms of biosynthesis of flavonoid glycosides are largely unknown in G. max. In the present study, 212

Current scenarios under global climate change envisage a considerable increase in ultraviolet B (UV-B) radiation in near future which may affect the productivity and yield quality of major agricultural crops. Present investigation was conducted to examine various defense strategies adopted against

Dietary isoflavones, daidzein and genistein are of huge interest in the nutraceutical field due to their practical application to postmenopause complications. This study is the first report an efficient method to prepare isoflavone rich soybean leaves (soyleaves) which is an edible food stuff in

O-methyltransferases (OMTs) catalyze the transfer of a methyl group from S-adenosine-L-methionine to a hydroxyl group of an acceptor molecule to form methyl ether derivatives and can modify the basic backbone of a secondary metabolite. A new O-methyltransferase, SOMT-9, was cloned from Glycine max

There are several branch points in the flavonoid synthesis pathway starting from chalcone. Among them, the hydroxylation of flavanone is a key step leading to flavonol and anthocyanin. The flavanone 3-beta-hydroxylase (GmF3H) gene was cloned from soybean (Glycine max cultivar Sinpaldal) and shown to

Mature soybean (Glycine max L. cv Harosoy 63) leaves normally contain kaempferol-3-glycosides but they accumulate no other flavonoids. Whole leaves sprayed with the diphenyl ether herbicide Acifluorfen and maintained in the light developed small necrotic lesions and accumulated isoflavone aglycones,

In the soybean (Glycine max (L.) Merr.), the gene combination Fg1 Fg3 is responsible for the glycosylation in the biosynthesis of kaempferol triglucoside (K9) in leaves. The presence of K9 is associated with reduction in chlorophyll content, specific leaf mass, photosynthetic rate and stomatal

We report the production of astragalin (AST) from regiospecific modifications of naringenin (NRN) in Escherichia coli BL21(DE3). The exogenously supplied NRN was converted into dihydrokaempferol (DHK) and then kaempferol (KMF) in the presence of flavanone-3-hydroxylase (f3h) and flavonone synthase

The metabolome of three soybean genotypes, Glycine max Hwangkeum (elite or domesticated cultivar), Glycine max Napjakong (landrace or semi-wild cultivar) and Glycine soja Dolkong (wild cultivar), were characterized in seeds and leaves using a ¹H NMR-based metabolomics approach. Expression
