Embodiment 1
[0138] Example 1: Preparation of Total Alkaloids of Fructus Trichosanthis Fructus
[0139] Take 5 kg of Trichosanthes and 5 kg of Allium, add 40% ethanol to reflux and extract twice, each time for 1 hour, combine the filtrates, recover the ethanol under reduced pressure and concentrate it to 60 ° C to measure the relative density to 1.10, let it cool, add ethanol to make the alcohol content reach 70%, stand overnight, filter, the filtrate recovers ethanol under reduced pressure, concentrates appropriately, adds hydrochloric acid to adjust pH2, passes through a cation exchange resin column, first elutes with water, and the water washing liquid is for later use; then elutes with 5% sodium chloride solution to If there is no alkaloid reaction, the sodium chloride eluate is collected, concentrated and dried, and extracted three times with absolute ethanol under reflux, combined, the ethanol is recovered under reduced pressure, concentrated, and dried to obtain the total alkaloids (...
Embodiment 2
[0140] Example 2: Preparation of Total Alkaloids of Fructus Trichosanthis
[0141] Take 1.5 kg of Trichosanthes meloni and 1 kg of Allium scallops, add 30% ethanol to extract 3 times, each time for 0.5 hours, combine the filtrates, recover the ethanol under reduced pressure and concentrate to 60 ° C to measure the relative density to 1.05, let it cool, add ethanol to make the alcohol content reach 50%, left overnight, filtered, the filtrate was decompressed to recover ethanol, concentrated appropriately, added hydrochloric acid to adjust the pH to 1, passed through a cation exchange resin column, first eluted with water, and the water washing solution was used for later use; then eluted with 20% sodium chloride solution to If there is no alkaloid reaction, the sodium chloride eluate is collected, concentrated and dried, extracted twice with absolute ethanol under reflux, combined, the ethanol is recovered under reduced pressure, concentrated, and dried to obtain the total alkal...
Embodiment 3
[0142] Example 3: Preparation of Total Alkaloids of Fructus Trichosanthis
[0143] Take 6 kg of Trichosanthes and 2 kg of Scallops, add 60% ethanol to reflux and extract once for 3 hours each time, combine the filtrates, recover the ethanol under reduced pressure and concentrate to 60 ° C to measure the relative density to 1.25, let it cool, add ethanol to make the alcohol content reach 80%, stand overnight, filter, the filtrate recovers ethanol under reduced pressure, concentrates appropriately, adds hydrochloric acid to adjust the pH to 4, passes through a cation exchange resin column, first elutes with water, and the water washing solution is used for later use; then elutes with 2% sodium acetate solution until nothing For alkaloid reaction, the sodium acetate eluate was collected, concentrated and dried, refluxed with absolute ethanol to extract 3 times, combined, the ethanol was recovered under reduced pressure, concentrated, and dried to obtain the total alkaloids (total ...
