[0027] A preparation method of nightshade fruit formula granules, said preparation method at least comprising the following steps:
[0028] Step 1, removing impurities and crushing fresh nightshade fruit to obtain decoction pieces;
[0029] Step 2, sequentially performing the first alcohol extraction and the second alcohol extraction on the decoction pieces to obtain the alcohol extract;
[0030] Step 3. Carrying out the first water extraction and the second water extraction sequentially on the medicinal dregs obtained through the second alcohol extraction to obtain a water extract;
[0031] Step 4. Concentrate the water extract in a vacuum environment below 80°C to obtain the first extract with a relative density of 1.07-1.09; place the alcohol extract in a vacuum environment for concentration , until there is no alcohol smell, the second extract is obtained;
[0032] Step 5, performing mixing treatment on the first extract and the second extract, followed by vacuum microwa...
Embodiment 1
[0057] The present embodiment provides a kind of preparation method of solanum nigrum formula granule, and described preparation method comprises the following steps at least:
[0058] Step 1, removing impurities and crushing fresh nightshade fruit with a total alkaloid content of not less than 12 mg / g, obtaining decoction pieces, and putting them into an extraction tank;
[0059] Step 2, sequentially performing the first alcohol extraction and the second alcohol extraction on the decoction pieces to obtain the alcohol extract;
[0060] The first alcohol extraction treatment is to add ethanol whose mass is 10 times that of the decoction pieces and whose volume concentration is 80% to the decoction pieces, soak for 24 hours, and collect the extract and medicinal residues; the second alcohol extraction The extraction process is to add ethanol with a volume concentration of 65% whose mass is 8 times the mass of the medicinal residues to the medicinal residues, and reflux extracti...
