The present invention relates to choleretic agents. Soujiyutsu is a member of the Compositae family.
Atractylodes lancea De
It is the rhizome of Canmdolle or its variants, and is a herbal medicine that has been used since ancient times as a stomachic, intestinal regulator, diuretic, and diaphoretic. The present invention has been made based on the discovery that atractylodine, the main component of Soujitsu, exhibits a choleretic effect, and based on this new knowledge, the present invention has been completed. That is, the present invention is a choleretic agent containing atractylodine as an active ingredient. Atractylodine, which is the active ingredient of the choleretic agent of the present invention, can be obtained, for example, as follows. The extract obtained by extracting Soujitsu with an organic solvent such as methanol, ethanol, diethyl ether, acetone, or ethyl acetate is subjected to column chromatography using silica gel, eluted with n-hexane, and the solvent is distilled off. Recrystallization of the yellow solid obtained by methanol from methanol yields atractylodine in the form of pale yellow columnar crystals. Extraction can be carried out at room temperature or by heating, but it is preferably carried out by heating to 30 to 80°C. A specific example of the production of atractylodine is as follows. Specific example 1 Add 5 times the amount, i.e. 150 ml, of an organic solvent such as methanol, ethanol (95%), diethyl ether, acetone, ethyl acetate, etc. to 30 g of soy sauce and boil at a temperature 5 to 10 degrees Celsius lower than the boiling point of the organic solvent used. Heat to reflux (digestion if diethyl ether is used) for 1 hour and filter the extract. Then, dry the filtrate to obtain 0.8g of dried extract powder.
was subjected to column chromatography using 8 g of silica gel, developed with n-hexane, separated into 10 ml portions, and distilled off the solvent from the eluted portion, which was found to be a single component by thin layer chromatography. 150 mg of atractylodine as a yellow solid was obtained, which was recrystallized from methanol to obtain 120 mg of atractylodine as pale yellow columnar crystals. The properties of atractylodine obtained as described above were as follows, and were consistent with the literature values [Pharmaceutical Journal, 80 , 1564 (1960)]. Atractylodine Color, properties: Pale yellow columnar crystals Melting point: 50-53° Specific light intensity: [α] 20 D ±0° (C=1.00, MeOH) Elemental analysis value (C 13 H 10 O) Calculated value (%) C; 85.69, H; 5.53, O;
8.78 Actual value (%) C; 85.75, H; 5.55, O;
8.70 Next, the fact that atractylodine exhibits a choleretic effect will be explained with reference to experimental examples and their results. Example 1 One male Wistar rat weighing around 300g
A group of 10 animals was used. After fasting for 6 to 8 hours, the abdomen of the rat was incised, a polyethylene cannula tube was inserted into the bile duct, and after a 1-hour stabilization period, 100 mg/Kg of atractylodine produced in Production Example 1 described above was placed in the duodenum. , and sodium dehydrocholate 100 mg/Kg, respectively.
The bile amount 30 minutes before was taken as 100%, and the percentage of the amount of bile flowing out thereafter was determined. As a control, the same rat as above was used, a polyethylene cannula was inserted into the bile duct in the same manner as above, and the percentage of bile volume was determined without administering any drug. The choleretic effect of atractylodine was then compared with that of a control and the administration of sodium dehydrocholate. The results are as shown in the drawing. The results shown in the drawings are the average of 10 rats per group. From the results shown in the drawings, it was confirmed that atractylozine has a significant choleretic effect similar to sodium dehydrocholate. Next, the acute toxicity of atractylodine will be explained by showing experimental examples and their results. Experimental Example 2 A group of 10 dd-Y male mice were used, each drug described in Experimental Example 1 was administered to the mice, and the number of deaths was observed for 7 days after administration, and the LD 50 was calculated from the number of deaths. . However, food and water were provided ad libitum during the observation period. The results are shown in Table 1. Note that the first
The LD 50 values in the table indicate the average value of 10 animals per group.

[Table] From the results shown in Table 1, it is clear that attractylodine
The LD 50 value is more than 3000 mg/Kg, whereas the LD 50 value of sodium dehydrocholate is 2050 mg/Kg.
This shows that the toxicity of atractylodine is quite low. Considering the experimental data on the choleretic effect of atractylodine and the results of acute toxicity tests, the effective dose of atractylodine varies depending on the age, weight, and severity of the disease of the patient, but is usually 1 dose of atractylodine for adults. 25-50mg once a day
It is considered appropriate to take the drug up to once. Atractylodine can be used as a choleretic agent as it is, but it can be made into powders, granules, tablets, and capsules by adding excipients, adjuvants, etc. used in ordinary formulations and following the usual method of manufacturing formulations. It can also be used in preparations such as drugs. EXAMPLES Next, the present invention will be specifically explained with reference to Examples, but the present invention is not limited thereto. Example 1 2.5 g of atractylodine was mixed with 96.5 g of lactose and 1 g of magnesium stearate, and this mixture was compressed using a single-shot tablet machine to form tablets with a diameter of 20 mm and a weight of approximately 23 mm.
A slug tablet of 20 to 50 mesh size was prepared, pulverized with an oscillator, and sieved to obtain good granules of 20 to 50 mesh particles. This granule is 1-2g at a time depending on the symptoms.
(equivalent to 25-50 mg of atractylodine) 1
Take once a day. Example 2 25g of atractylodine and 195g of crystalline cellulose
and 5 g of magnesium stearate,
This mixture was compressed into tablets with a diameter of 7 mm using a single-shot tablet machine.
mm, 225 mg tablets were manufactured. One tablet contains 25 mg of atractylodine. Take 1 to 2 tablets once a day depending on your symptoms. Example 3 Add 25g of atractyrosin to potato starch
Mix with 315g, add water and knead, 1mm x 1mm
It is granulated using a screen with a mesh of After drying, sieve with a No. 16 mesh sieve. Next, add 10g of magnesium stearate to this granule.
were mixed and compressed using a tablet machine to produce tablets each weighing 350 mg. One tablet contains 25 mg of atractylodine. Take 1 to 2 tablets at a time, depending on your symptoms.
Take once a day. Example 4 5 g of atractylodine, 43 g of lactose and 2 g of magnesium stearate were mixed and 500 mg each was filled into hard capsules. One capsule of this product contains 50 mg of atractylodine. This capsule is to be taken once a day, depending on the symptoms.
