Examples
Embodiment 1
[0040] Take 1000g of Yangjinhua slices, add water and decoct twice, 10 times the amount each time, decoct for 2 hours, combine the decoction liquid, centrifuge, adjust the pH=3, centrifuge, and the supernatant passes through the cation at 4 times the column volume / hour Exchange resin (001×7, hydrogen type, diameter-to-height ratio 1:8), wash with water until the effluent is colorless, add 3% hydrochloric acid for elution, and the elution rate is 2 times the column volume / hour, collect the eluent, until The alkaloid test was negative (the effluent was added dropwise with 10% silicotungstic acid without precipitation), neutralized to neutral with sodium hydroxide, desalinated, and the filtrate was concentrated and dried to obtain the total alkaloids of Datura japonica.
Embodiment 2
[0042] Get 1000g of Teng Gong Teng decoction pieces, add acidic water with pH=5 for percolation, combine the percolation solution and add water to dilute to 10000ml, centrifuge, adjust pH=1, centrifuge, supernatant passes through cation exchange resin (AmberliteIR- -120, hydrogen type, diameter-to-height ratio 1:6), washed with water until the effluent was colorless, then eluted with 0.5% hydrochloric acid solution, the elution rate was 4 times the column volume / hour, after elution was 2 times the column volume, soaked for 5 hours, then eluted until the alkaloid test was negative (the effluent was added dropwise with 10% silicotungstic acid without precipitation), collected this part of the eluate, neutralized to neutral with calcium hydroxide, desalinated, and the filtrate was concentrated and dried to obtain Ding Gongteng total alkaloids.
Embodiment 3
[0044] Take 5 kg of yangjinhua decoction pieces, add 70% ethanol to ultrasonically extract twice, add 5 times the amount each time, ultrasonically for 0.5 hours, combine the extracts, centrifuge, recover ethanol, add water to 5000ml, adjust pH = 2, centrifuge, and supernatant Pass through the upper cation exchange resin (001×10, sodium type, diameter-to-height ratio 1:7) at 2 times the column volume / hour, wash with water until the effluent is colorless, and then use 6% sulfuric acid solution (containing 1mol / L of CaCl 2 ) elution, the elution rate is 5 times column volume / hour, collect the eluate until the alkaloid test is negative (the effluent is added dropwise with 10% silicotungstic acid without precipitation), and neutralized to neutral with sodium hydroxide, Desalting, the filtrate was concentrated and dried to obtain the total alkaloids of Dajinhua.
