Verification of the Body Fat-Reducing Effect

[0035]The body fat-reducing effect was verified in the following manner. First, 21 male SD rats (CHARLES RIVER LABORATORIES JAPAN, INC.) at the age of 4 weeks were given a standard feed (MF feed, produced by Oriental Yeast Co., Ltd.) for acclimation for one week. Then, the rats were divided into 3 groups so that the average body weight was almost equal among the groups.

[0036]Separately, a feed was prepared by adding cholesterol, sodium cholate, corn oil, a hot water extract of dried powder of pueraria flower (containing 10 wt % of isoflavones: produced by Ohta's Isan Co., Ltd.) to the standard feed so that these components are contained in the resultant feed in proportions of 1 wt %, 0.25 wt %, 10 wt %, and 5 wt %, respectively. This feed is referred to as a test feed.

[0037]A feed was prepared in the same manner as the above-described test feed, except that a soybean extract (containing 10 wt % of isoflavones: produced by FUJI OIL CO., LTD...

Examination of the Body Fat-Reducing Effect and the Anti-Obesity Effect

[0041]An effect of the processed pueraria flower regarding fat accumulation in subcutaneous fat and visceral fat was examined in the following manner using female ICR mice at the age of 7 weeks. First, 35 ICR mice were given a standard feed (MF feed, produced by Oriental Yeast Co., Ltd.) for acclimation for one week. Then, the mice were divided into 5 groups of 7 each so that the average body weight per group was uniform.

[0042]Separately, a feed (test feed 1) was prepared by adding 5 wt % of pueraria flower extract (containing 10 wt % of isoflavones and 1 wt % of saponin, produced by Ohta's Isan Co., Ltd.), 40 wt % of beef tallow, and 9 wt % of granulated sugar to the standard feed.

[0043]A feed (test feed 2) was prepared in the same manner as the above-described preparation method of the test feed 1, except that 5 wt % of pine bark extract containing 75 wt % of proanthocyanidins and 5 wt % of catechins (this pine...

Abstract

The present invention provides a body fat-reducing agent containing a processed pueraria flower as an active component. The body fat-reducing agent has a superior body fat-reducing effect. Furthermore, the body fat-reducing agent may contain at least one of a lipid absorption suppressing component and a lipid metabolism promoting component. A food product, which contains the body fat-reducing agent, provided according to the present invention has superior effects of preventing body fat accumulation and reducing body fat.

Description

TECHNICAL FIELD[0001]The present invention relates to a body fat-reducing agent.BACKGROUND ART[0002]Kudzu, which is a leguminous plant, has been used as a raw material for food, a raw material of Chinese herbal medicines and the like for a long time. For example, the starch from kudzu has been used as a raw material of traditional Japanese confectionery. The root and flower of kudzu, which are respectively called pueraria root and pueraria flower, have been used as raw materials of Chinese herbal medicines for antipyretic, analgesic and spasmolytic effects, and improvement of symptoms such as sweating.[0003]Among these, pueraria flower is known to contain various components, including flavonoids. In recent years, it has become clear that pueraria flower has an effect of improving hepatopathy, an effect of preventing a hangover, an effect of improving urinary nitrogen metabolism, and other effects, which are not provided by other leguminous plants (e.g., Japanese Patent No. 3454718, ...
