Example Embodiment
[0018] Example 1
[0019] Under stirring, 50 grams of crude tobacco extract extract containing 14% solanesol was dissolved in 50 ml of n-hexane, and used after the dissolution was complete. Take 50ml of ethanol and 5g of sodium hydroxide and mix them evenly, add them to the above mixed solution, heat to an inner temperature of 60°C and stir for saponification for 3 hours, cool to room temperature and filter the reaction solution for use.
[0020] Put about 300 grams of the processed macroporous adsorption resin HZ-802 (processed in accordance with the conventional processing methods of ion exchange resin and adsorption resin) into a glass column with a diameter of 5 cm and a length of 100 cm. The lower end is a PTFE piston. The sand core at the upper end of the piston is No. 2 sand core. Pass the above mixture into a glass column at room temperature for about 10 minutes, and then use a) 2000ml of ethanol; b) 10000ml of acetone: ethanol = 1:1 mixture; c) 2000ml of acetone to rinse,...

[0021] Example 2
[0022] Under stirring, 50 grams of crude tobacco extract extract containing 14% solanesol was dissolved in 50 ml of n-hexane, and used after the dissolution was complete. Take 50ml of methanol and 5g of sodium hydroxide and mix them evenly, add them to the above mixed solution, heat to an inner temperature of 60°C and stir for saponification for 3 hours, cool to room temperature and filter the reaction solution for later use.
[0023] Put about 300 grams of the processed macroporous adsorption resin HZ-803 (processed in accordance with the conventional processing methods of ion exchange resin and adsorption resin) into a glass column with a diameter of 5 cm and a length of 100 cm, with a polytetrafluoroethylene piston at the lower end. The sand core at the upper end of the piston is No. 2 sand core. Pass the above mixture into a glass column at room temperature for about 10 minutes, and then use a) 2000ml of ethanol; b) 10000ml of acetone: ethanol = 1:1 mixture;...

[0024] Example 3
[0025] Under stirring, 50 grams of crude tobacco extract extract containing 14% solanesol was dissolved in 50 ml of n-hexane, and used after the dissolution was complete. Take 50ml of ethanol and 7g of potassium hydroxide and mix them evenly, add them to the above-mentioned mixed solution, heat to an inner temperature of 60°C and stir for saponification for 3 hours, cool to room temperature and filter the reaction solution for use.
[0026] Put about 300 grams of the processed macroporous adsorption resin HZ-816 (processed in accordance with the conventional processing methods of ion exchange resin and adsorption resin) into a glass column with a diameter of 5 cm and a length of 100 cm, with a polytetrafluoroethylene piston at the lower end. The sand core at the upper end of the piston is No. 2 sand core. Pass the above mixture into a glass column at room temperature for about 10 minutes, and then use a) 2000ml of methanol; b) 10000ml of a mixture of acetone: me...
