Embodiment 1

[0042] A preparation process of Populus tomentosa leaf total flavonoids, comprising the steps of:

[0043] SA1. Extraction: Take the leaves of Populus tomentosa, crush them, add 10 times the amount of 70% ethanol solution, heat and reflux for extraction for 3 times, each time for 1.5 hours; combine the extracts, and concentrate under reduced pressure to 50 Each ml of the concentrated solution is equivalent to 1g of the crude drug liquid extract by heat measurement at ℃, and the crude extract of Populus tomentosa leaves is obtained, which is stored in cold storage for later use.

[0044] SA2. Separation of D101 macroporous adsorption resin: take twice the amount of D101 macroporous adsorption resin loaded into the chromatography column, rinse with 95% ethanol until the eluent is clear, and then rinse with distilled water until there is no alcohol smell; slowly drip Add the sample, the dripping speed is 0.5 times the column volume / h, stop washing after the sample is loaded, and ...

Abstract

The invention belongs to the technical field of traditional Chinese medicine and particularly relates to pressure sore removing cream prepared from total flavonoids of populus tomentosa leaf and a preparation process of the pressure sore removing cream. The flavonoids in the populus tomentosa leaf are subjected to heating reflux extraction with 70% ethanol, further separation and purification areperformed with D101 macroporous resin and polyamide resin, the total flavonoids of the populus tomentosa leaf are obtained, and the cream is prepared from the total flavonoids of the populus tomentosaleaf. The cream is prepared from the total flavonoids of the populus tomentosa leaf and cream base in parts by weight as follows by mixed processing: 0.4-10.0 parts of the total flavonoids of the populus tomentosa leaf, 5.0-45.0 parts of water, 0.42-3.75 parts of glycerin, 0.94-8.43 parts of stearic acid, 0.08-0.75 parts of vaseline, 0.42-3.75 parts of lanolin, 0.44-3.98 parts of liquid paraffin,0.30-2.70 parts of glyceryl monostearate and 0.1-0.9 parts of triethanolamine stearate soap. The cream has good treatment effect on pressure sores.

Description

technical field [0001] The invention belongs to the technical field of traditional Chinese medicines, and relates to an external cream for treating trauma, in particular to a cream of Populus tomentosa leaves for removing pressure sores and a preparation process thereof. Background technique [0002] Pressure sores are long-term bedridden patients. Due to extreme physical weakness, loss of sensory and motor functions, inability to change lying positions, and improper care, the skin tissue and even muscles located between the bony prominence on the body surface and the mattress may suffer from continuous pressure. , local hypoxia, vascular embolism, ulcers formed by tissue necrosis and decay. Its formation process is divided into three stages: erythema stage, vesicular stage and ulcer stage. The incidence of pressure sores is as high as 1-4.7%, which has become a major problem in clinical nursing work. According to relevant literature, about 60,000 people die of pressure sor...
