Embodiment 1

[0024] Example 1 The preparation of the processed product of Coptidis officinalis of the present invention

[0025] Take Evodia rutaecarpa and add appropriate amount of water to decoct, mix the decoction with Jinghuanglian, wait for the liquid to be absorbed, and fry to dry. For every 100kg of net coptis, use 10kg of Evodia rutaecarpa.

experiment example 2

[0026] Experimental Example 2 Preparation of Extract from Cornus Rhizoma Coptis Rhizome Processed Products of the Present Invention

[0027] Take the net Yuzhi Coptis chinensis, add water to decoct 3 times, 3 hours each time, add 10 times the amount of water each time, filter, combine the extracts, concentrate, and set aside.

[0028] According to the above process, the extracts of Coptis chinensis and Coptis chinensis were extracted and prepared, and the content of total polysaccharides was also determined on the basis of the determination of total alkaloids.

[0029] Determination method of total alkaloids: Accurately weigh 0.4g of the extract, put it into a 25mL measuring bottle, add ethanol to dilute to the mark, shake well, and test by column chromatography. Precisely measure 5mL, put it on the treated alumina column (about 0.9cm inner diameter, 5g neutral alumina, wet packing, pre-wash with 30mL ethanol), elute with 35mL ethanol, collect the eluate and put it in 50mL In...

[0034] Embodiment 3 The quality control method of Huanglian of the present invention

[0035] (1) TLC identification

[0036]Take 0.1g of this product powder, add methanol 50ml, ultrasonic treatment for 30min, and the filtrate is used as the test solution. Take jatrorrhizine hydrochloride, tetrandrine hydrochloride, epiberberine hydrochloride, coptisine hydrochloride, palmatine hydrochloride and berberine hydrochloride plus methanol to make a solution containing 0.1 mg per 1 ml, as a reference solution. Precisely measure 1.5ml of each reference substance solution and add it to the same 10ml measuring bottle, dilute to the mark with methanol, and use it as a mixed reference substance solution. According to the test of thin-layer chromatography (Appendix VI B of the Chinese Pharmacopoeia in 2005), draw 10 μl of each of the above-mentioned three solutions, respectively spot on the same silica gel G thin-layer plate, and use cyclohexane-ethyl acetate-isopropanol- Methanol-ammoni...

Abstract

The invention provides application of golden thread in preparing medicaments, such as an insulin sensitizer and a PPAR-gamma agonist, in particular relates to application in restraining 3T3-L1 pre-adipocyte cell differentiation, enhancing the utilization ratio of 3T3-L1 pre-adipocyte glucose or reducing blood fat and improving insulin resistance or diabetes medicaments. The invention also provides a medicinal composition for restraining 3T3-L1 pre-adipocyte cell differentiation and enhancing the utilization ratio of glucose. The golden thread and the extract thereof have the advantages of restraining 3T3-L1 pre-adipocyte cell differentiation, improving insulin resistance and treating diabetes and complicating diseases thereof, and achieving remarkable medicament effect which is superior to that of berberine hydrochloride and crude golden thread.

Description

technical field [0001] The invention relates to a new application of Yuhuanglian, in particular, the application in the preparation of drugs for insulin sensitizers and PPARγ agonists.
