  EXAMPLES Hereinafter, although an Example is shown and this invention is demonstrated concretely, this invention is not restrict | limited to the following Example.

Example 1
Fermented tea extract using TUA4337L strain to give 1- (3 ', 4', 5'-trihydroxyphenyl) -3- (2 '', 4 '', 6 ''-trihydroxyphenyl) -propan-2-ol Generated. Specifically, it is as follows. In addition, 1- (3 ′, 4 ′, 5′-trihydroxyphenyl) -3- (2 ″, 4 ″, 6 ″ -trihydroxyphenyl) -propan-2-ol is referred to as fermentation catechin.
<Fermentation procedure>
(1) 1% v / v inoculation of TUA4337L from glycerol stock to MRS (10mL) (2) Culture (30 ℃, 20hr)
(3) After centrifugation (8,000rpm, 5min, 4 ℃), remove supernatant (4) Wash with sterilized water in the same volume as the culture solution (× 2)
(5) Prepare bacterial solution using sterilized water so that OD ₆₆₀ = 10. (6) Centrifugation after adding 10w / v% tea powder (Cargill Japan) to sterilized water and suspending (8,000rpm, 5 min), 0, 0.04, 0.2, 1 w / v% of yeast extract (BD) is added to the supernatant (Bx 11.9), and 1 v / v% of the bacterial solution prepared in (5) is added (7) Culture (35 ℃)

The obtained culture broth was diluted with pure water, further diluted 2-fold with 40% acetonitrile, treated with a 0.45 μm filter, and subjected to the following analysis. A typical HPLC chart is shown in FIG. 1, and the production results of fermented catechins are shown in FIG.
<HPLC analysis conditions>
Column: capcell pak C18, 4.6mmφ × 150mm, 5μm (Shiseido)
Mobile phase: A 0.05% TFA / H ₂ O, B 90% CH ₃ CN, 0.05% TFA / H ₂ O
Gradient: B 5 → 35v / v% (0 → 13min), B 35 → 70v / v% (13 → 20min), B 70v / v% (20 → 25min)
Flow rate: 1.0mL / min

Injection volume: 10μL

  As shown in FIGS. 1 and 2, when tea extract was fermented using TUA4337L, epigallocatechin (EGC) decreased with time, and fermented catechin was produced. Moreover, the production | generation rate accelerated by adding yeast extract. In addition, it confirmed by NMR that the new peak of C in FIG. 1 was fermentation catechin.

Example 2
The production of fermented catechins by various strains belonging to lactic acid bacteria was examined.

  Using various strains of L. pentosus and L. plantarum as lactic acid bacteria, the productivity of fermented catechins was examined together with the JCM reference strain. As L. pentosus, TUA4337L, AF43, AF48, AF51, AF64 and JCM standard strain 1558T were examined, and as L. plantarum, AF70, AF71, AF62, AF63 and JCM standard strain 1149T were examined. Using these lactic acid bacteria, productivity of fermented catechin was evaluated in the same procedure as in Example 1 (examined with tea extract supplemented with 0 w / v% and 1 w / v% yeast extract). Specifically, the concentration of fermented catechin in the culture solution after culturing for 72 hours was quantified. The results are shown in FIG.

  From FIG. 3, L. pentosus produced fermented catechins regardless of the strain, whereas L. plantarum was unable to produce fermented catechins in any strain.

Example 3
The effect of fermented catechin obtained in Example 1 on sympathetic nerve activity in brown adipose tissue was examined. The fermented catechin obtained in Example 1 is a product obtained by isolating and concentrating the peak fraction of fermented catechin from the culture solution in Example 1 and then precipitating it by lyophilization.

  Specifically, in the experiment, 3 Wistar male rats (approx. 9 weeks old, n = 3 for each group) with a body weight of about 300 g were bred for 1 week under a light / dark cycle every 12 hours (lighted for 12 hours from 8 o'clock). After fasting for anesthesia and urethane anesthesia, a cannula for duodenal administration was inserted, and then the sympathetic nerve branch of the interscapular brown adipose tissue was lifted with a silver electrode, and the electrical activity of the nerve was measured. At the time when the measurement value of this nerve settled (around 13:00), 1 mL of each test sample (control: sterilized water, fermented catechin: 1 μg / mL aqueous dispersion) was cannulated into the duodenum and sympathetic nerves in brown adipose tissue Changes in activity were measured electrophysiologically. The results are shown in FIG.

  FIG. 4 shows that the fermentation catechin significantly increased in the BAT-SNA value compared to the control. Thus, fermented catechins were thought to enhance sympathetic activity in brown adipose tissue. Moreover, since it was thought that this enhancement of sympathetic nerve activity is a mechanism for enhancing energy metabolism, the following was demonstrated.

Example 4
The effect of enhancing energy metabolism and promoting fat burning by the fermented catechin obtained in Example 1 was examined. The fermented catechin used was prepared in the same manner as in Example 3.

Specifically, oral administration of 250 μL of sterile water was continued for 5 days in C57BL / 6J mice (7 weeks old, male), and they were accustomed to oral administration. Then, it divided into the control group and the fermentation catechin group so that a difference might not appear in the average value of a body weight (each n = 4). After putting the mouse in the chamber of the energy metabolism measuring device (Oxymax, Bioresearch Center) and getting used to the environment for 2 days, the diet was switched to a high fat diet (60 kcal% FAT, Research Diet) and the oxygen in each mouse Measurement of consumption (VO ₂ (mL / kg / hr)) and emission carbon dioxide emission (VCO ₂ (mL / kg / hr)) was started. Each mouse was orally administered 250 μL of test sample per day (control: sterile water, fermented catechin: 5 mg / mL aqueous dispersion) and continued administration for 11 days. The calorie consumption and the respiratory quotient were calculated by the following formula.
Calories burned: VO ₂ x (RER x 1.232 + 3.815) / 1000
Where RQ (breathing quotient) = VCO ₂ / VO ₂

  By administration of fermented catechins, an increase in calorie consumption was seen compared to the control group. The calorie consumption up to the 11th day was compared, and the data before administration and on the 4th day are shown in FIG. This is a result of analyzing calorie consumption in the light period (resting period: AM 7:00 to PM 19:00), and calorie consumption was significantly increased in the fermented catechin group. Since this is an effect in the resting period, it was considered that basal metabolism was improved by fermented catechin, and it was confirmed that there was an action of promoting energy metabolism. Moreover, in order to verify the change of the fat burning effect before and after administration of fermented catechin, the respiratory quotient was measured. The respiratory quotient is a volume ratio of carbon dioxide emission to oxygen consumption until nutrients are decomposed in vivo and converted into energy. It is widely used as an index for understanding the outline of how much nutrients are burned in the body. In other words, the respiratory quotient reflects the energy source consumed. In general, the highest quotient is the carbohydrate (RQ = 1.0), and the lowest is the lipid (RQ≈0.7). That is, when a large amount of fat is burned, the amount of carbon dioxide emitted is less than the amount of oxygen consumed, and the value of the respiratory quotient decreases. The lower this value, the more fat is burned, and the higher the fat burning effect. FIG. 6 shows the difference in respiratory quotient before administration and on the 11th day after administration, but compared to the control group, the respiratory quotient is lower when fermented catechin is administered, and the fat burning effect is promoted. Conceivable.

Example 5
The body temperature increasing action by the fermented catechin obtained in Example 1 was examined. The fermented catechin used was prepared in the same manner as in Example 3.

  Specifically, C57BL / 6J mice (10 weeks old, male) bred on a high fat diet (60 kcal% FAT) for 2 weeks were tested with 250 μL of test sample per day (control: sterile water, fermented catechin: 1.6 mg / mL aqueous dispersion) was orally administered (each n = 11 to 12). Five minutes and 60 minutes after oral administration, rectal temperature was measured using a microprobe thermometer (BAT-12, muromachi), and the change width of rectal temperature was calculated. The results are shown in FIG.

  From FIG. 7, fermented catechin significantly increased the rectal temperature relative to the control. Therefore, it is considered that fermented catechin has an effect of increasing body temperature.

Example 6
The anti-obesity action by the fermented catechin obtained in Example 1 was examined. The fermented catechin used was prepared in the same manner as in Example 3.

  Specifically, C57BL / 6J mice (7 weeks old, male) were bred on a high fat diet (60 kcal% FAT) for 2 weeks. Meanwhile, oral administration of 250 μL of sterilized water was continued for 5 days to accustom them to oral administration. Then, it divided into the control group and the fermentation catechin administration group so that a difference might not appear in the average value of a body weight (each n = 4). Each mouse was orally administered 250 μL of test sample per day (control: sterile water, fermented catechin: 5 mg / mL aqueous dispersion), and body weight was measured over time. The change in weight gain is shown in FIG.

  From FIG. 8, the tendency to suppress weight gain is recognized by administering fermented catechins, and fermented catechins are considered to have an anti-obesity effect. As this action mechanism, the action of promoting energy metabolism is considered as well as the effect of increasing body temperature.
