Embodiment 1
[0060] Extraction and purification method of indole alkaloids
[0061] After 9.3kg of dried C. chinensis whole herb was crushed into coarse powder, reflux extracted with 95% industrial ethanol for 3 times, each time for 2 hours, concentrated under reduced pressure, and recovered the solvent to obtain 1756g of alcohol extract; mix it 1:1 After being suspended in water and dispersed, sequentially extract 1:1 with petroleum ether, chloroform, ethyl acetate, and n-butanol, each polar solvent is extracted 6 times, and each extract is combined separately, and the solvent is recovered by a rotary evaporator , Obtain petroleum ether part extract (286.6g), chloroform part extract (244.9g), ethyl acetate part extract (188.6g), n-butanol part extract (205.1g) and water part.
[0062] The extract from the petroleum ether part is dissolved in a solvent, and then mixed with silica gel (100-200 mesh), the sample is dry-applied to a silica gel column, and the silica gel column chromatography ...
