Embodiment 1

[0035] Example 1: Preparation of mullein and mullein glycosides

[0036] Take 10 kg of dried astragalus medicinal materials, extract 3 times (2 hours, 1 hour, 1 hour) with 8 times the amount of 80% ethanol under reflux, filter, combine the filtrate, recover the solvent under reduced pressure, and concentrate until no alcohol taste to obtain the alcohol extract of astragalus. Placed in a refrigerator at 4°C overnight, the supernatant was adsorbed with D101 type macroporous resin, first eluted with pure water until the effluent was clear, and then eluted with 50% ethanol until TLC detected no verbasin spots. The 50% ethanol eluate was collected and concentrated under reduced pressure, and then extracted 7 times with an equal volume of ethyl acetate. After the extracts were combined, the solvent was recovered and dried under vacuum to obtain the total flavonoids of astragalus. The total flavonoids of Astragalus were then chromatographed on 200-300 mesh silica gel column with chlorof...

Embodiment 2

[0040] Example 2 Preparation of granules of pharmaceutical composition of the present invention (active ingredient is verbasil glycoside)

[0041] Verbascum glycosides 1mg

[0042] Starch 500mg

[0043] Microcrystalline cellulose 500mg

[0044] The preparation method: after mixing the verbasil glycosides with various auxiliary materials uniformly, the soft material is prepared with an appropriate amount of water, granulated, dried, granulated, and packed.

Embodiment 3

[0045] Example 3 Preparation of a tablet of the pharmaceutical composition of the present invention (active ingredient is verbasil glycoside)

[0046] Verbascum glycosides 20mg

[0047] Lactose 127mg

[0048] Corn starch 50mg

[0049] Magnesium stearate 3mg

[0050] Preparation method: Pass the Verbasil glycosides through an 80-mesh sieve, mix them with lactose and corn starch uniformly, add an appropriate amount of water and granulate the powder, after drying, the granules are sieved and mixed with other excipients, and then compressed into tablets. .

Description

Technical field [0001] The invention relates to the field of Chinese medicine pharmacy. Specifically, it relates to a medicinal composition with mullein and mullein glycosides as active ingredients and its application in preparing drugs for preventing and treating diabetic nephropathy. Background technique [0002] Diabetic nephropathy (diabetic nephropathy, DN) is a common complication of diabetes and one of the manifestations of diabetic systemic microangiopathy. It usually refers to the thickening of glomerular basement membrane, mesangial expansion and extracellular matrix proliferation caused by diabetes, leading to the kidney High filtration and proteinuria of the pellet. The clinical features are proteinuria, progressive renal impairment, hypertension, edema, and severe renal failure in the late stage, which is one of the main causes of death in patients with diabetes. According to statistics, about 30-40% of diabetic patients will experience kidney damage. In the Unite...
