Abstract

The invention discloses U.S. rattan fruit leaf extract application in preparing hypoglycemic drug.The extracting method of U.S. rattan fruit leaf extract comprises the steps: to take U.S. rattan fruit leaf, and addition solvent decocts and extracts, filter extracting solution, concentrates.U.S. rattan fruit leaf efficacy effect is focused by the present invention, uses natural plant extracts, it is to avoid the Western medicine toxic and side effects to human body.Extracting method is simple, and mode is flexible.U.S. rattan fruit leaf extract belongs to plant extract, and stable effect is gentle, does not finds obvious toxic-side effects temporarily, avoids the drawback of tradition Western medicine aggravation diabetes sequela while playing hypoglycemic activity.Carrying out mouse test with U.S. rattan fruit leaf extract, the U.S. rattan fruit leaf extract of result of study display 50mg/kg.BW dosage group i.e. has the effect significantly reducing blood sugar for human body level, thus it is speculated that containing hypoglycemic functional component in U.S. rattan fruit leaf.

Description

U.S. rattan fruit leaf extract application in preparing hypoglycemic drug
Technical field
The present invention relates to U.S. rattan fruit leaf, specifically, relate to U.S. rattan fruit leaf extract in preparing hypoglycemic drug Application.
Background technology
U.S. rattan fruit, belongs to Euphorbiaceae U.S. rattan fruit and belongs to, for perennial bejuco, 2006 after South America introduces China The ground plantations such as Hainan, Yunnan, Guangxi, 2013, China's Ministry of Public Health approval oil and fat of sacha inchi was new resource food.U.S. rattan fruit leaf is Papery alternate leaf, the most avette or wealthy heart, long 9-15 cm, wide 6-10 cm;Top is tapering or short-tail is sharp, and base portion is the most truncated, limit Edge tool knuckle-tooth or irregular sawtooth, have body of gland.Have no the report about U.S. rattan fruit leaf extract at present.
Fasting glucose normal value is at below 6.1mmol/L, and the normal value of two hours blood glucoses is at below 7.8mmol/L after the meal, If above this scope, referred to as hyperglycemia.Under normal circumstances, human body can this two adjusts greatly by hormonal regulation and neuroregulation Joint system guarantees that the source of blood glucose keeps balance with outlet, makes blood glucose maintain certain level.But at inherited genetic factors (such as glycosuria Sick family history) with under the common effect of environmental factors (such as irrational meals, obesity etc.), two big regulatory functions get muddled, Arise that blood sugar level raises.Western medicine such as sulphanylureas, biguanides, insulin, glycosidase inhibitor, Main Function is to stimulate pancreas Island element is secreted, improves human body sensitivity, is slowed down sugar transition and absorption;But Western medicine the most all can have side effect, modal pair Effect is hypoglycemia and the damage to liver.Frequently hypoglycemia can cause hypomnesis, dizziness, unable, old and feeble, consequence is the tightest Weight is the biggest to damage to patient.
Summary of the invention
It is an object of the invention to overcome the deficiencies in the prior art, it is provided that U.S. rattan fruit leaf extract is preparing hypoglycemic drug In application.
To achieve these goals, the present invention adopts the following technical scheme that
Present invention discover that U.S. rattan fruit leaf extract has significant effect of lowering blood sugar.
The extracting method of above-mentioned U.S. rattan fruit leaf extract comprises the steps: to take U.S. rattan fruit leaf, adds solvent and decocts Extract, filter extracting solution, concentrate.
As preferably, in said extracted method, described solvent is water or ethanol or its mixture.
As preferably, in said extracted method, the consumption of described solvent is 1-40 times of U.S. rattan fruit foliage weight.
As preferably, in said extracted method, the consumption of described solvent is 8-20 times of U.S. rattan fruit foliage weight.
As preferably, in said extracted method, the consumption of described solvent is 10-15 times of U.S. rattan fruit foliage weight.
As preferably, in said extracted method, the number of times of described solvent extraction is 1-3 time, each 0.2-6 hour.
As preferably, in said extracted method, when described concentration refers to be concentrated into 25 DEG C relative density be 1.1~ 1.3。
Compared with prior art, there is advantages that U.S. rattan fruit leaf efficacy effect is carried out by the present invention Focus on, use natural plant extracts, it is to avoid the Western medicine toxic and side effects to human body.Extracting method is simple, and mode is flexible.Beautiful Rattan fruit leaf extract belongs to plant extract, and stable effect is gentle, does not finds obvious toxic-side effects temporarily, plays hypoglycemic activity While avoid tradition Western medicine aggravation diabetes sequela drawback.Mouse test is carried out, research with U.S. rattan fruit leaf extract Result display 50mg/kg.BW dosage group U.S. rattan fruit leaf extract i.e. have significantly reduce blood sugar for human body level effect ( Notable blood sugar decreasing effect can be presented in 1-3h), thus it is speculated that containing hypoglycemic functional component in U.S. rattan fruit leaf.
Accompanying drawing explanation
Fig. 1 is that U.S. rattan fruit leaf water extract affects figure to blood glucose in diabetic mice level.
Detailed description of the invention
In order to be more clearly understood that the technology contents of the present invention, describe in detail especially exemplified by following example, but the present invention Embodiment be not limited to this.
Embodiment 1: U.S. rattan fruit leaf water extract
Take U.S. rattan fruit leaf dry product 10Kg, wash, add 10 times of weight water, soak 1 hour, heated and boiled 3 hours, mistake Filter, when concentrating the filtrate to 20 DEG C, relative density reaches 1.3, and concentrated solution is spray-dried, and obtains dry fine powder 1.25Kg.
Embodiment 2: U.S. rattan fruit leaf combination (water+ethanol) extract
Take U.S. rattan fruit leaf dry product 10Kg, wash, add 8 times of weight water, soak 1 hour, heated and boiled 3 hours, mistake Filter, when concentrating the filtrate to 20 DEG C, relative density reaches 1.2, concentrated solution 8 times of weight 80% ethanol ultrasonic extraction 2 hours, mistake Filter, merging filtrate, lyophilization obtains dried object 0.65Kg.
The pharmacodynamic experiment of embodiment 3. embodiment 1
Diabetic mice is tested, and investigates the blood sugar decreasing effect of extract
With conventional antidiabetic drug glibenclamide as positive control, by normal mouse and diabetic mice are carried out glucose tolerance examination Test (GTT) and blood sugar lowering therapeutic test, have studied the hypoglycemic activity of U.S. rattan fruit leaf water extract.Result shows, 50mg/kg BW dosage group can significantly reduce mouse blood sugar level, controls within normal range by the blood glucose value of mice, the most upon administration In the range of 1-3h, its effect is better than glibenclamide;Illustrate that the water extract of U.S. rattan fruit leaf can be obviously improved the height of diabetic mice Blood glucose symptom, has good hypoglycemic activity.U.S. rattan fruit leaf water extract impact such as Fig. 1 on blood glucose in diabetic mice level Shown in.
The pharmacodynamic experiment of embodiment 4. embodiment 2
With reference to embodiment 3, changing embodiment 1 therein into embodiment 2, other are constant.Result shows, 50mg/kg BW dosage Group can significantly reduce mouse blood sugar level, control within normal range by the blood glucose value of mice, the most upon administration 1-3h In the range of its effect be better than glibenclamide;Illustrate that U.S. rattan fruit leaf (water+ethanol) extract can be obviously improved diabetic mice Hyperglycemic symptoms, has good hypoglycemic activity.
