Embodiment 1

[0095] A kind of Rauwolfia root extract, it is made by following preparation steps:

[0096] After the roots of Rauvolwolfia hainanensis are naturally dried at room temperature and protected from strong light, they are crushed and sieved, and 50g of dry powder is taken, placed in an extraction container, and distilled water is added to 8 times the amount of medicinal materials, decocted for 1 hour, and the operation is repeated 3 times; the crude extract is obtained with gauze After filtration, the crude extract filtrate is concentrated under reduced pressure with a rotary evaporator, and the parameters of the rotary evaporator are set to: temperature 50°C, vacuum 70kPa; then slowly add 95% ethanol to the concentrated solution, and stir quickly until the concentration of ethanol in the concentrated solution The concentration is 70%, and when the concentrated solution is slowly lowered to room temperature, move it to the refrigerator and refrigerate overnight; filter the next da...

Embodiment 2

[0099] A kind of Rauwolfia root extract, it is made by following preparation steps:

[0100] Induce emetic Rauwolfia root, dry it naturally at room temperature, avoid strong light, crush it, take 100kg of dry powder, put it in an extraction container, add 5 times the amount of distilled water of the medicinal material, decoct for 0.8 hours, repeat the operation 3 times; the crude extract is filtered with gauze , the crude extract filtrate is concentrated under reduced pressure by a rotary evaporator, and the parameters of the rotary evaporator are set to: temperature 80°C, vacuum 50kPa; then slowly add 95% ethanol to the concentrated solution, and stir quickly until the concentrated solution ethanol concentration is 70 %, when the concentrated solution is slowly lowered to room temperature, move it to a 10°C freezer and refrigerate overnight; filter the next day, remove the filter residue, freeze the filtrate to -45°C, and then freeze-dry it by gradually increasing the temperat...

Abstract

The invention relates to a heat-clearing, anti-inflammatory and analgesic herb extract, and specifically relates to a rauvolfia extract and its preparation method. And the preparation of the extract comprises the steps of: selecting rauvolfia, drying in the shade naturally and pulverizing; taking a proper amount of dried rauvolfia powder , adding 8-10 times amount of distilled water, and decocting in an appropriate container; filtering and condensing the filtrate; adding 95% ethanol, adjusting the ethanol concentration of the concentrated liquor to 70%, and allowing the liquor to stand overnight at a low temperature; filtering and removing the filter residue; freeze-drying the filtrate, thus obtaining freeze-dried powders as the product. The rauvolfia extract of the invention has an obvious effect in clearing heat, resisting inflammation and easing pain, and it can also be prepared into a heat-clearing, anti-inflammatory and analgesic medicine.
