Description

Uric acid reducing traditional Chinese medicine composition and preparation method thereof
Technical Field
The invention relates to the technical field of traditional Chinese medicine health care and preservation, in particular to a uric acid-reducing traditional Chinese medicine composition and a preparation method thereof.
Background
Hyperuricemia and hyperglycemia are common metabolic disorders. Uric acid is the final metabolite of purine compounds in humans, and hyperuricemia is caused by excessive uric acid in humans and by insufficient body excretion. Because the human body lacks enzymes capable of decomposing purine compounds, excessive uric acid can only be discharged out of the body by kidney metabolism, and once kidney metabolism dysfunction or food containing a large amount of purine is ingested, the uric acid concentration in the human body is overhigh, and the hyperuricemia can be diagnosed when the blood uric acid concentration of two non-same days is more than 420 umol/L. Uric acid concentration is too high, which can crystallize into the urinary acid salt, deposit in joint synovium, bursa, cartilage and other tissues, and cause gout. Modern medicine divides hyperuricemia into a formation increase type and a excretion decrease type according to causes, and selects uric acid generation inhibiting drugs such as allopurinol or uric acid excretion promoting drugs such as tribromouron, probenecid, benzenesulfonazone and the like according to renal function conditions. Although these drugs have remarkable uric acid lowering effect, side effects such as rash, fever, liver and kidney dysfunction, hematopoietic dysfunction, gout attack and the like are also large.
Therefore, it is expected by those skilled in the art to provide a Chinese medicinal composition which has good safety, less side effects, is suitable for long-term administration, and can effectively reduce uric acid in vivo, and a preparation method thereof.

Comparative example 2
The comparative example differs from example 3 only in that the comparative example used Gynura procumbens and cyclocarya paliurus which were treated only with the enzyme deactivation and tea frying machine, but the pile fermentation was not performed on the Gynura procumbens and cyclocarya paliurus. The rest conditions and steps are as described in example 3, and oral liquid is prepared.
Comparative example 3
The difference between this comparative example and example 3 is that the oral liquid material of this comparative example does not contain divided wood and orange peel. The rest conditions and steps are as described in example 3, and oral liquid is prepared.
Efficacy verification of the traditional Chinese medicine composition:
in order to verify the efficacy of the traditional Chinese medicine composition in reducing uric acid and blood sugar, the prevention and alleviation effects of the oral liquid in the process of hyperuricemia of rats are researched by establishing a rat hyperuricemia model and taking a model rat as a research object. The test includes the following:
(1) Molding a hyperglycemic rat: 2.10g of citric acid was added with 100mL of double distilled water to prepare a 0.1mmol/L citric acid solution, 2.94g of sodium citrate was added with 100mL of double distilled water to prepare a 0.1mmol/L sodium citrate solution, the two solutions were mixed in a ratio of 1:1 to prepare a citric acid buffer (pH 4.5), and Streptozotocin (STZ) was dissolved therein to prepare a 1% STZ solution.
SD male rats with the weight of (200+/-20) g are purchased, 66 normal SD rats are adaptively fed for 1 week, 50 healthy rats are selected and randomly divided into a model group and a treatment group (an oral liquid in example 3), 25 rats in each group are randomly injected with a freshly prepared STZ solution in the abdominal cavity, the injection dose is 60mg/kg, the fasting blood glucose concentration is measured after 72 hours, and the fasting blood glucose concentration of the rats is more than or equal to 16.7mmol/L and is manifested as symptoms such as polydipsia, polyphagia, diuresis and the like, which indicates that the molding of the hyperglycemic rats is successful.
The fasting blood glucose concentration was measured before the start of the test, rats in the treatment group were each filled with 600mg/kg of oral liquid (recommended average daily dose for adults 6g, and according to average weight for men and women of adults 60kg, the daily dose was 100mg/kg., which is about 6 times the daily dose for rats calculated from unit volume, and 600 mg/kg), 9:00 am each day, and the model group was given an equal volume of distilled water for 30 days, and after 12 h days of fasting, the tail was cut, and blood was taken, respectively, to measure the fasting blood glucose concentration.
(2) Hyperuricemia model group: male SPF-grade SD rats were purchased for 84, 6-8 weeks old, and the body mass was 180-220 g/rat. Rats were fed adaptively for 1 week and then divided into a control group (control group was filled with distilled water daily), a model group, an allopurinol group, a control group 1 (comparative example 1 oral liquid), a control group 2 (comparative example 2 oral liquid), a control group 3 (comparative example 3 oral liquid), and a treatment group (example 3 oral liquid), each group being 12. The other groups except the control group were molded by administering 25mg/kg adenine and 300mg/kg potassium oxazinate, respectively, 1 time per day, and stomach was continuously irrigated for 3 weeks. Elevated blood uric acid suggests successful molding.
Starting administration treatment from the induction model, and pouring the allopurinol group into the stomach according to the dosage of 20mg/kg of allopurinol; the treatment group, the comparison group 1 and the comparison group 3 are subjected to gastric lavage according to the dosage of 600 mg/kg; the control group is given the same dose of distilled water for gastric lavage; 1 time per day for 3 consecutive weeks. And (3) observing the indexes: serum Uric Acid (UA) before and after administration, blood is collected from the retroorbital venous plexus of a rat by about 1.5 ml, naturally coagulated at 25 ℃ at room temperature for 1h, centrifuged at 2500r/min for 5min, and the serum is separated and assayed for UA.
(3) The experimental results are as follows:
TABLE 1 comparison of blood glucose concentrations in rats of each group)
Note that: * The representation is significantly different from the model set (P<0.05) ,
As can be seen from Table 1, the blood glucose concentration of rats in the treatment group was reduced after 30 days of continuous gastric lavage with 600mg/kg oral liquid, and the blood glucose concentration was relatively stable after 10 days. The blood sugar concentration of the 10d, 20d and 30d treatment groups is obviously different from that of the model group (P is less than 0.05), which shows that the blood sugar concentration of the rats of the long-term gastric lavage oral liquid is lower than that of the model group.
TABLE 2 comparison of blood uric acid concentrations in rats of each group)
Note that: * The representation is significantly different from the model set (P<0.05),
As can be seen from Table 2, the differences were statistically significant (P > 0.05) in comparison with blood uric acid from the groups prior to administration. After administration, the blood uric acid level of the model group is increased compared with that of the control group, which indicates that the model is successfully manufactured. Compared with the model group, allopurinol group, comparison group 1 to comparison group 3 and treatment group showed significantly reduced blood uric acid, and the difference was statistically significant. Allopurinol group decreased blood uric acid concentration in rats compared to pre-dose, while treatment group could not decrease blood uric acid concentration compared to pre-dose, but increased blood uric acid concentration by about 10.6% before and after dose in treatment group compared to model group by nearly 56%; blood uric acid concentrations were increased by 22.7%, 25.4%, 22.2% before and after dosing of control 1 to control 3. This demonstrates that the oral liquid of the present invention can effectively suppress the rate of elevation of blood uric acid under the same feeding and disturbing conditions as compared with the comparative groups 1 to 3.
The above experiment is described by taking the oral liquid of example 3 as an example, but the decoction pieces of example 1 and the instant medicinal powder of example 2 have similar effects.
