Embodiment 1N1
[0030] Example 1N 1 , N 5 , N 10 -The preparation of three-(E)-coumaroyl spermidine
[0031](1) Extraction: 1 kg of broken rapeseed pollen, pulverized. Using supercritical CO 2 For extraction, the temperature of supercritical carbon dioxide extraction is 40° C., the pressure is 35 MPa, and the entraining agent is ethanol, and its consumption is 8% of the weight of the broken pollen. Collect the residue fraction. The residue part was ultrasonically extracted three times with 90% ethanol to obtain the active part.
[0032] (2) Separation and purification: 200 g of the active site obtained in the above step (1) was extracted with ethyl acetate, and evaporated to dryness under reduced pressure. Mix the ethyl acetate part with silica gel and put it on the column, and perform silica gel (300-400 mesh) column chromatography (silica gel 10 times the mass of the sample, 120cm*6cm column). Use chloroform-methanol (15:1-1:1) for gradient elution, in which the gradient 15:1 eluted ...
Embodiment 2N1
[0033] Example 2N 1 , N 5 , N 10 -The preparation of three-(E / Z)-coumaryl spermidine
[0034] (1) Extraction: the method is the same as the (1) step in Example 1.
[0035] (2) Separation and purification: 200 g of the active site obtained in the above step (1) was extracted with ethyl acetate, and evaporated to dryness under reduced pressure. Mix the ethyl acetate part with silica gel and put it on the column, and perform silica gel (300-400 mesh) column chromatography (silica gel 10 times the mass of the sample, 120cm*6cm column). Use chloroform-methanol (15:1-1:1) for gradient elution, in which the gradient 15:1 eluted 1000ml, 12:1 eluted 1000ml, 10:1 eluted 1000ml, 5:1 eluted 1000ml, 1:1 1 eluted 1000ml, collected the 30th-40th fraction, each fraction was 50ml, combined, evaporated to dryness under reduced pressure and then repeated column chromatography with 12:1 chloroform-methanol, collected the 7th-13th fraction, each fraction was 15ml, reduced After being evaporat...
