(Industrial Application Field) The present invention relates to an antidiabetic agent containing ginsenoside Rb 2 as an active ingredient. (Prior art and problems to be solved by the invention) Ginsenoside Rb 2 is a ginseng saponin isolated from ginseng (root of Panax ginseng CAMEYER) and has the following chemical name and chemical structural formula. & Pharmaceutical Bretain〓S.SANAD et.al.,

According to a report by Kimura, Waki et al. (Kyoritsu Shuppan Co., Ltd., Medicinal Ginseng, first edition, p. 169), the hypoglycemic effect of ginseng saponin on alloxan-induced diabetic mice is rather negative. (Means for solving the problem) The present inventors have studied the effects of various carrot saponins on biological metabolism for many years.
Quite unexpectedly, we found that ginsenoside Rb 2 in ginseng saponin had a significant antidiabetic effect. As a method for investigating the above-mentioned pharmacological action of ginsenoside Rb 2 , a method of measuring the glucose content in the serum of hyperglycemic rats is employed. The hypoglycemic effect, toxicity, etc. of ginsenoside Rb 2 are shown below along with test methods. Experiment 1 Hyperglycemia lowering test in strepitozotocin-induced diabetic rats (1) Preparation of pathological animals Wistar male rats (body weight around 120 g) were used to feed solid feed (CE-2 protein manufactured by Clea Japan).
(24.0% fat, 3.5% lipid, 60.5% carbohydrate) and water were available ad libitum, and the breeding room was maintained at constant temperature and humidity (25°C relative humidity 60%), with a light/dark cycle every 12 hours. Streptozotocin 65mg/Kg body weight (10m
M, citrate buffer (PH4.5)) was administered intraperitoneally, and 4 to 5 days later, samples were taken from the tail vein and measured using an enzymatic method (glucose oxidase method), and the blood sugar level was confirmed. A group of 6 to 7 animals served as a test group and a control group. (2) Antidiabetic effect 10 mg of ginsenoside Rb 2 was dissolved in 0.5 ml of physiological saline and administered intraperitoneally to test rats once a day for 1 to 9 days. Breeding conditions and blood sugar levels were measured using the same methods as above. Voting was done 12 hours after administration. (3) Results

[Table] Experiment 2 Acute Toxicity Experimental Method A group of 10 male dd mice was administered, and the sample was dissolved in physiological saline and administered intraperitoneally, and the number of deaths was calculated 6 days later.
Asked for LD50 . Ginsenoside Rb 2 LD 50 : 305 mg/Kg (Effects of the invention) As is clear from the above experiments, ginsenoside Rb 2 significantly increases serum glucose concentration in both single administration and continuous administration over several days. Although the effect becomes more pronounced with continuous administration, it does not cause hypoglycemic symptoms and the effect persists even after administration is discontinued. Therefore, administration of this drug is effective in improving the condition of diabetes and is useful in its treatment. Diabetes mellitus is often accompanied by not only an increase in blood sugar levels, but also an increase in lipids such as triglycerides and an increase in ketone bodies. Jinshinosedo
Rb 2 also shows a remarkable improving effect on these.
On the other hand, even after long-term continuous administration, animal dynamics, necropsy,
No metabolic abnormalities were observed. Ginsenoside Rb 2 used in the present invention can be administered orally or parenterally in the form of powder, granules, tablets, capsules, injections, etc., either as is or mixed with appropriate pharmaceutical carriers, excipients, and diluents. I can do it. For example, for adults, the dosage is 30 ml per day.
mg to 1000 mg, preferably 50 mg to 300 mg, is administered orally or injected in 1 to 3 doses, but it goes without saying that the dose may be increased or decreased depending on age, body weight, and symptoms. Next, formulation examples of the antidiabetic agent of the present invention will be described. (1) Granules Uniformly mix 100 mg of ginsenoside Rb 2 , 616 mg of lactose and 264 mg of cornstarch, and add 10
%Hydroxypropylcellulose (HPC)
Using the aqueous solution as a pasting agent, prepare granules according to the Japanese Pharmacopoeia, General Rules for Preparations, Granules section. (2) Injection Dissolve 50 mg of ginsenoside Rb 2 in 2.5 ml of 20% propylene glycol distilled water solution, sterilize with heat, and prepare an injection according to the Japanese Pharmacopoeia General Provisions for Injection.
