Embodiment 1
[0077] Embodiment 1, the preparation of pharmaceutical tablet of the present invention
[0078] Step 1) Take 500g of seabuckthorn and 500g of Puhuang, immerse in ethanol with 8 times volume concentration ratio of 70% (V / V) for 2 hours, reflux extraction twice, the first time for 2 hours, and the second time for 7 times the amount of ethanol , 1.5 hours, filtered, the filtrates were combined, the ethanol was recovered until there was no alcohol smell, and the alcohol extract was obtained; the alcohol extract was loaded on the AB-8 macroporous resin, eluted with 1.5 times the column volume of water, and the eluent was discarded Continue to elute with 3 times of column volume and concentration of 20% (V / V) ethanol, discard the eluent after reclaiming ethanol; continue to wash with 4 times of column volume and concentration of 70% (V / V) ethanol Ethanol was recovered from the eluate, and when concentrated to 50°C, the relative density was 1.25 to obtain the seabuckthorn and Puhuang...
Embodiment 2
[0082] Embodiment 2, the preparation of pharmaceutical capsule of the present invention
[0083] Step 1) Take 800 g of seabuckthorn, soak it with 9 times the amount of 80% (V / V) ethanol for 1.5 hours, reflux extraction twice, the first time for 2 hours, the second time for 8 times the amount of ethanol for 1 hour, filter, and combine the filtrates , recover ethanol until there is no alcohol smell, and obtain the alcohol extract; load the alcohol extract on YWD12G macroporous resin, elute with 1 times column volume of water, and discard the eluate; continue to use 2 times column volume at a concentration of 30 % (V / V) ethanol was eluted, and the eluent was discarded after reclaiming ethanol; continue to elute with 4 times the column volume and a concentration of 80% (V / V) ethanol, and the eluate was reclaimed ethanol, concentrated to 40 The relative density at ℃ is 1.20, and seabuckthorn extract is obtained;
[0084] Step 2) Take 900g of Puhuang, soak it with 8 times the amoun...
Embodiment 3
[0088] Embodiment 3, the active ingredient determination of medicine of the present invention
[0089] 1. Determination of isorhamnetin, kaempferol and quercetin content
[0090] Get respectively step 3) in the embodiment 2 and dry and pass the powder (seabuckthorn and Puhuang intermediate) 0.5g of the No. Intermediate) 0.5g,
[0091] Accurately weigh, put in a stoppered Erlenmeyer flask, accurately add 50ml of ethanol, weigh, heat and reflux for 1 hour, let cool, weigh again, make up the lost weight with ethanol, shake well, filter, and accurately measure Take 25ml of the filtrate, put it in a stoppered Erlenmeyer flask, add 3.5ml of hydrochloric acid, heat and hydrolyze in a 75°C water bath for 1 hour, cool, transfer to a 50ml volumetric flask, and add ethanol to the mark.
[0092] Determination by HPLC (Appendix IVD of Chinese Pharmacopoeia 2010 Edition). Condition: octadecylsilane bonded silica gel column; mobile phase: methanol-0.4% phosphoric acid (58:42); UV detector...
