摘要:
An object of the present invention is to provide a method for measuring equal in a biological sample by an immunological method, a kit for the measurement, and a method for determining equol-producing ability of a subject. The measurement method of the present invention is characterized in that S-equol is used as at least one antigen selected from the group consisting of a standard antigen used for the preparation of a standard curve and a labeled antigen that competes with equol in a biological sample. The kit of the present invention is characterized in including S-equol as at least one antigen selected from the group consisting of the standard antigen and the labeled antigen. The determination method of the present invention includes steps of measuring equal in a biological sample derived from a subject who has ingested soybean isoflavane by an immunological method using S-equol as at least one antigen selected from the group consisting of the standard antigen and the labeled antigen, and determining an equol-producing ability of the subject based on the measured value of equol obtained in the above step.

The present application provides a composition for improvement in physical activity efficiency, a composition for reducing fatigue, and a composition for improving dynamic/kinetic visual acuity, comprising a kaempferol analog.
摘要:
Provided is a means useful for enjoying the physiological action of kaempferol. A plant extract contains 1 mg/g or more of a kaempferol aglycone on a dry-weight basis.
摘要:
An object of the present invention is to provide a fermented product containing equol-producing microorganisms in the state of living cells by which equol production ability is maintained. When producing a fermented material by using an (equol-producing microorganism, with soybean powder or soybean milk as raw materials, (1) preparing a mother starter by fermentation under anaerobic conditions by using an equol-producing microorganism in the presence of a daidzein species at pH 5.0 or higher, (2) preparing a bulk starter by fermentation under anaerobic conditions by using said mother starter in the presence of a daidzein species at pit 5.0 or higher, and (3) preparing a fermented material by fermentation by using said bulk starter in a medium containing soybean powder or soybean milk, enables production of a fermented material containing microorganisms in the state of living cells in which the equol production ability is maintained.

The present invention provides a composition for improvement in physical activity efficiency, a composition for reducing fatigue, and a composition for improving dynamic/kinetic visual acuity, comprising a plant-derived extract and/or a plant-derived processed product.
摘要:
An object of the present invention is to provide enzymes associated with equol synthesis, genes coding such enzymes, and a process for producing equol and its intermediates using the enzymes and genes. The present invention provides a dihydrodaidzein synthesizing enzyme, tetrahydrodaidzein synthesizing enzyme, equol synthesizing enzyme, and genes coding these enzymes. The present invention also provides a process for synthesizing dihydrodaidzein, tetrahydrodaidzein, and/or equol using these enzymes.
