Problems solved by technology

For the treatment of diabetes, western medicine mostly adopts diet, oral hypoglycemic drugs and insulin replacement.
[0003] Diabetes mellitus (DM, Diabetes Mellitus) is a metabolic disorder syndrome characterized by chronic hyperglycemia associated with genetic factors and various environmental factors. Although there are some drugs with different targets for the treatment of diabetes, sometimes Can not achieve the expected therapeutic effect

Embodiment 1

[0028] Embodiment one: the preparation of Artemisia sativa preparation

[0029] See attached figure 1 , specifically describe the preparation of Xinjiang Yizhi Artemisia preparation as follows:

[0030] (1), first crush the whole Artemisia argyi in Xinjiang into powder, weigh and add 3 times the volume of ether and place it for 8 hours before filtering, and the precipitate is ultrasonically extracted with 80% ethanol at 35°C, each time for 30-40min, and filtered to obtain Artemisia argyi ethanol extract;

[0031] (2) Precipitate the Artemisia argyi extract with 95% ethanol overnight, filter, remove the ethanol by rotary evaporation, extract with ethyl acetate, the extraction temperature is normal temperature, and obtain the ethyl acetate part, and the ethyl acetate part is subjected to polyamide column chromatography Adopt 20%, 40%, 60%, 80% ethanol solutions of different concentrations to elute successively, collect 60% and 80% ethanol eluate and concentrate under reduced p...

Embodiment 2

[0033] Embodiment two: the preparation of Xinjiang Artemisia argyi preparation

[0034] See attachedfigure 1 , according to the technical scheme described in Example 1, by pulverizing the whole Artemisia chinensis, weighing and adding 3 times the volume of ether, leaving it for 8 hours and then filtering, the precipitate was ultrasonically extracted with 80% ethanol at 35 ° C, each time 30- For 40 minutes, filter to obtain the ethanol extract of Artemisia chinensis, precipitate with 95% ethanol overnight, centrifuge to take the supernatant, extract with ethyl acetate, the extraction temperature is normal temperature, filter to obtain the ethyl acetate part, and the ethyl acetate part is subjected to polyamide column chromatography 20%, 40%, 60%, and 80% ethanol solutions of different concentrations were used for elution in sequence, and the 60% and 80% ethanol eluates were collected, concentrated under reduced pressure into extracts, and the concentrated extracts were combined ...

Embodiment 3

[0036] Example 3: Establishment of Experimental Alloxan Diabetic Mouse Model

[0037] Get 120 Kunming male mice with a body weight of 18-22g, feed them adaptively for one week, and randomly select 10 as the normal control group (Nomal control group, NC). Saline configuration), fasting before injection for 12 hours, resulting in an experimental hyperglycemia model, giving 10% glucose water within 48 hours after the model was built, to prevent hypoglycemic death of animals, after 72 hours, blood was taken from the tail of the mice to measure blood sugar (The mice were fasted for 12 hours before blood collection). Observe the drinking water and feed intake of the animals, and whether the typical "three excesses" symptoms of diabetes appear. Finally, the mice whose blood glucose level was ≥11.1mmol / L were selected as experimental diabetic animal models.

[0038] Alloxan can cause damage to islet β cells, thereby affecting the secretion of insulin and increasing blood sugar in an...

Abstract

The invention discloses an artemisia rupestris preparation used in medicaments for treating diabetes and a preparation method thereof. The preparation method comprises the following steps: crushing artemisia rupestris herbs; weighing the powder; adding ethyl ether of which the volume is 3 times of the volume of the powder; standing for 8 hours, and then, filtering; ultrasonically extracting precipitates with 80% ethanol at 35 DEG C for 30-40 minutes every time; filtering to obtain an ethanol extracting solution; precipitating with 95% ethanol, centrifuging, and taking a supernatant solution; extracting ethyl acetate; filtering to obtain an ethyl acetate part; carrying out polyamide column chromatography on the ethyl acetate part; eluting by sequentially adopting ethanol solutions with different concentrations of 20%, 40%, 60% and 80%; collecting ethanol eluate obtained by adopting the ethanol solutions with the concentrations of 60% and 80%; concentrating while depressurizing to obtain an extract; proportioning the obtained extract and a milk vetch extract according to the weight ratio of (5-10):1; and preparing a certain amount of pure water to obtain a finished preparation. The prepared artemisia rupestris preparation has the activity of reducing blood sugar, the using dose of the artemisia rupestris preparation is 67.5mg / kg, and the artemisia rupestris preparation has wide application fields in medicaments for treating diabetes.

Description

field of invention [0001] The invention relates to the technical field of Chinese herbal medicine preparations. Specifically, the present invention relates to the technical field of preparation and preparation of Artemisia xinjiang used in medicines for treating diabetes. Background technique [0002] In recent years, due to many factors such as the improvement of living standards, changes in dietary structure, increasingly tense pace of life, and less active and more sedentary lifestyle, the incidence of diabetes worldwide has increased rapidly. Diabetes has become the third largest disease after tumors and cardiovascular diseases. Chronic diseases that seriously threaten human health. For the treatment of diabetes, western medicine mostly adopts methods such as diet, oral hypoglycemic drugs, and insulin replacement. Natural medicine has the advantages of rich sources, less toxic and side effects, easy to accept and long-term use. Therefore, in recent years, the research ...
