Embodiment 1
[0033] 1. Preparation of crude extract:
[0034] Grind 250g jujube kernels, pass through a 40-mesh sieve, degrease with petroleum ether, add 1200ml, 800ml, 600ml of 70% ethanol aqueous solution, heat and reflux for extraction 3 times, each time for 1 hour, filter, and combine the extracts , the filtrate is concentrated with ethanol until it has no alcohol smell, then dissolved with 2 times the amount of water, extracted 5 times with n-butanol, the extract is concentrated under reduced pressure, and the solvent is recovered to obtain the n-butanol crude extract, which is the sample to be separated. figure 1 shown.
[0035] 2. Using high-speed countercurrent chromatography to separate magnolialine, spinosin, and 6″’-feruloylspinosin:
[0036] Take n-butanol, ethyl acetate and water at a volume ratio of 2:3:5, place them in a separatory funnel to prepare a two-phase solvent system, take the upper phase as the stationary phase, and the lower phase as the mobile phase; fill the st...
