Embodiment 1
[0100] Embodiment 1 Preparation of Artemisia argyi effective components
[0101] Artemisia argyi leaves are pulverized, passed through a 20-mesh sieve, added 8 times the amount of ethyl acetate:ethanol=1:1, heated and refluxed for 1 hour, extracted 2 times, added 8 times the amount of 70% ethanol to the dregs, heated and refluxed for 1 hour, extracted 2 times Once, the filtrate was combined to obtain the extract, after the extract was concentrated, the sample was dissolved with 5% ethanol, and the ODS-C18 column was crossed. At first, 1250ml of 5% ethanol was used as the mobile phase, and then 1250ml of 50% ethanol was replaced as the mobile phase to obtain a wash. Remove the liquid, and continue to separate the eluent by preparative liquid chromatography. Separation conditions: the chromatographic column is an Agilent preparative column (Zorbax SB-C18; 21.2mm×250mm), the mobile phase is water A and acetonitrile B, and the gradient elution procedure is as follows
