Embodiment 1
[0044] Example 1: add 8 to 10 times the amount of water to the aboveground part of Artemisia fragrans, boil and extract twice at 80°C to 100°C, each time for 2 hours to 3 hours, filter, combine the filtrates, and concentrate to one-third of the original volume , add 1 to 2 times the volume of the concentrated solution of absolute ethanol and place it for precipitation for 12 hours, filter the precipitate, adjust the pH value to 3 to 6 with dilute hydrochloric acid after the filtrate is concentrated, and put it on the AB-8 macroporous resin chromatography column , after all the sample solution is absorbed, rinse the column with 3 to 8 column volumes of deionized water, and then perform gradient elution with 50%, 70%, and 90% ethanol, and the amount of ethanol per concentration is 3 to 8. 8 chromatographic column volumes, the flow rate is 2 to 5 chromatographic column volumes per hour, collect the ethanol eluent, combine and concentrate at 60°C to 90°C, and then dry the concentra...
Embodiment 2
[0045] Example 2: Add 8 to 10 times the amount of water to the aboveground part of Artemisia marina, boil and extract twice at 80°C to 100°C, each time for 2 hours to 3 hours, filter, combine the filtrates, and concentrate to one-third of the original volume , add 1 to 2 times the volume of the concentrated solution of absolute ethanol and place it for precipitation for 12 hours, filter the precipitate, adjust the pH value to 3 to 6 with dilute hydrochloric acid after the filtrate is concentrated, and put it on the AB-8 macroporous resin chromatography column , after all the sample solution is absorbed, rinse the column with 3 to 8 column volumes of deionized water, and then perform gradient elution with 30%, 50%, and 70% ethanol, and the amount of ethanol per concentration is 3 to 8. 8 chromatographic column volumes, the flow rate is 2 to 5 chromatographic column volumes per hour, collect the ethanol eluent, combine and concentrate at 60°C to 90°C, and then dry the concentrate...
Embodiment 3
[0046] Example 3: add 8 to 10 times the amount of water to the aerial parts of Artemisia marina, boil and extract twice at 100°C, each time for 2 hours to 3 hours, filter, combine the filtrates, concentrate to one-third of the original volume, and add the concentrate 1 to 2 times the volume of absolute ethanol was left to settle for 12 hours, filtered to remove the precipitate, and the filtrate was concentrated and adjusted to a pH value of 3 to 6 with dilute hydrochloric acid, put on an AB-8 macroporous resin chromatography column, and waited for sample loading After the solution is completely absorbed, wash the column with 3 to 8 column volumes of deionized water, and then perform gradient elution with 10%, 30%, and 50% ethanol. The amount of ethanol per concentration is 3 to 8 column volumes. The column volume and the flow rate are 2 chromatographic column volumes per hour. The ethanol eluents are collected, combined and concentrated at 60°C to 90°C, and the concentrated sol...
