Embodiment 1
[0060] Implementation example 1: the preparation of berberine
[0061] Take an appropriate amount of Coptis rhizome powder, add 5 times the amount of 30% ethanol to reflux and extract for 3 times, extract for 2 hours each time, filter, combine the filtrate, concentrate the filtrate to 40°C and measure the relative density to 1.45, let it cool, add 1% glacial acetic acid, A large amount of precipitate precipitated, and the precipitate was filtered and removed. The solution is added with concentrated hydrochloric acid to adjust the pH value to 3-4, and left overnight to obtain yellow needle-shaped crystals. The yellow needle-shaped crystals are recrystallized with an organic solvent, and calcium hydroxide is used to adjust the pH value to 8.5-9.0, and the obtained product has a purity of more than 98%. Berberine.
Embodiment 2
[0062] Implementation example 2: the preparation of berberine
[0063] Take an appropriate amount of Coptis rhizome powder, add 5 times the amount of 60% ethanol to reflux and extract for 3 times, extract for 2 hours each time, filter, combine the filtrate, concentrate the filtrate to 40°C and measure the relative density to 1.45, let it cool, add 1% glacial acetic acid, A large amount of precipitate precipitated, and the precipitate was filtered and removed. The solution is added with concentrated hydrochloric acid to adjust the pH value to 3-4, and left overnight to obtain yellow needle-shaped crystals. The yellow needle-shaped crystals are recrystallized with an organic solvent, and calcium hydroxide is used to adjust the pH value to 8.5-9.0, and the obtained product has a purity of more than 98%. Berberine.
Embodiment 3
[0064] Implementation example 3: the preparation of berberine
[0065] Take an appropriate amount of Coptis rhizome powder, add 5 times the amount of 75% ethanol to reflux and extract for 3 times, extract for 2 hours each time, filter, combine the filtrate, concentrate the filtrate to 40°C and measure the relative density to 1.45, let it cool, add 1% glacial acetic acid, A large amount of precipitate precipitated, and the precipitate was filtered and removed. The solution is added with concentrated hydrochloric acid to adjust the pH value to 3-4, and left overnight to obtain yellow needle-shaped crystals. The yellow needle-shaped crystals are recrystallized with an organic solvent, and calcium hydroxide is used to adjust the pH value to 8.5-9.0, and the obtained product has a purity of more than 98%. Berberine.
