Embodiment 1
[0048] Embodiment 1, ethanol extraction process
[0049] Take gardenia medicinal material 1000g, impregnate with 9 times the amount of 30% (V / V) ethanol for 1.5 hours, reflux extraction twice, the first time for 2.5 hours, the second time for 6 times the amount of ethanol for 1.5 hours, filter, combine the filtrates, Recover ethanol under reduced pressure until there is no alcohol smell (-9Pa, 60°C) to obtain the alcohol extract; load the alcohol extract on ADS-17 macroporous resin, elute with 2 times the column volume of water, and discard the eluent; Continue to elute with 3 times column volume and 20% (V / V) ethanol, discard the eluent after reducing pressure to recover ethanol (-9Pa, 60°C); continue to use 4 times column volume and 50% concentration (V / V) ethanol was eluted, the eluent was decompressed to recover ethanol (-9Pa, 60°C), concentrated under reduced pressure (-9Pa, 70°C) to a relative density of 1.30 at 40°C, and the extract was obtained for future use. The obt...
Embodiment 2
[0050] Embodiment 2, tablet
[0051]Get the extract obtained in Example 1, add 25g of starch, mix well, dry at 80°C, pulverize, pass through a 40 mesh sieve, add 15g of microcrystalline cellulose, make soft material with 6% starch slurry, pass through a 14 mesh sieve for granulation, 60 Dry at ℃ until the moisture is lower than 5%, pass through a 14-mesh sieve and granulate to obtain an intermediate, add magnesium stearate according to 1% of the weight after granulation, mix well, and compress into tablets to obtain 1000 tablets. The intermediate prepared above contains 0.1% of the medicinal ingredient shanzhiside methyl ester.
Embodiment 3
[0052] Embodiment 3, water extraction process
[0053] Take 800g gardenia medicinal material, add 10 times the amount of water to soak for 1 hour, decoct twice, the first time is 2 hours, the second time is 8 times the amount of water, 1.5 hours, filter, combine the filtrates, and concentrate under reduced pressure to 1 gram of crude drug / ml (-9Pa, 80°C) to get the water extract, load the water extract on the ADS-17 macroporous resin, elute with 1.5 times the column volume, and discard the eluate; continue to use 2 times the column volume , the concentration is 10% (V / V) ethanol elution, and the eluent is discarded after reclaiming ethanol; Continue to elute with 5 times of column volume, concentration is 60% (V / V) ethanol, and the eluent is decompressed Recover ethanol (-9Pa, 60°C), concentrate under reduced pressure (-9Pa, 70°C) to a relative density of 1.25 at 45°C, and obtain an extract for future use, and add the obtained extract to pharmaceutically acceptable excipients...
