Multi-element lycopene phosphatide compound and preparation method thereof

[0045] Dissolve 1 g of natural multi-component lycopene powder (5% lycopene, 0.5% phytoene, 0.5% phytoene) and 0.5 g soybean lecithin in 40 mL of ether, at 25 °C Reflux in a water bath (stir while refluxing) for 3 hours, take it out, filter, and vacuum-dry the filtrate to obtain the obtained product. Take an appropriate amount, dissolve it with dichloromethane, and fix the mobile phase to volume. It can be seen that the content of lycopene, phytoene, and phytoene are 1.59%, 0.15%, and 0.15%, respectively, through HPLC detection.

[0047] Dissolve 1.4g of natural multi-lycopene oleoresin (10% lycopene, 1% phytoene, 1% phytoene) and 3g egg yolk lecithin in 600mL ether, at 25°C Reflux in a water bath (stir while refluxing) for 7 hours, take out and filter, and vacuum-dry the filtrate to obtain the obtained product. Take an appropriate amount, dissolve it in dichloromethane, and fix the volume of the mobile phase. It can be seen that the content of lycopene, phytoene, and phytoene are 3.26%, 0.32%, and 0.31%, respectively, through HPLC detection.

[0049] 1 g of natural multivariate lycopene powder (the content of lycopene is 5%, the content of phytoene is 0.5%, and the content of phytoene is 0.5%) and 0.5 g of egg yolk lecithin are dissolved in 40 mL of ethyl acetate, Reflux in a water bath at 45°C (stir while refluxing) for 3 hours, take out and filter, and vacuum-dry the filtrate to obtain the obtained product. Take an appropriate amount, dissolve it in dichloromethane, and fix the volume of the mobile phase. It can be seen that the content of lycopene, phytoene, and phytoene are 0.19% and 1.98% through HPLC detection.
