Abstract
The invention relates to the field of organic synthesis, in particular to a preparation method of alpha-GPC. The method includes the steps of S1, weighing 2-3g of phospholipid, and dissolving into 100-150mL of tertiary butanol; S2, adding a 15-20mL of prepared sodium tert-butoxide-tertiary butanol solution into the solution obtained in S1; S3, placing the solution obtained in S2 on a reflux device, and performing condensation reflux for 5-6 hours; S4, performing vacuum distillation drying on the solution obtained in S3, adding 20-25mL of petroleum ether, removing supernate, and performing vacuum drying on the precipitate. The method has the advantages that tertiary butanol has three methyl, the methyl is electrode pushing groups and can increase the activity of hydroxyl, and the formed sodium tert-butoxide has high catalytic activity and can well promote phospholipid hydrolysis to form the alpha-GPC; the sodium tert-butoxide is compounded by using a metal organic frame structure, and the metal organic frame structure has an adjustable gap structure and can increase the carrying capacity of the sodium tert-butoxide; in addition, the metal organic frame structure Fe-MIL-101 has goodsolubility in the tertiary butanol and can well achieve homogeneous catalysis to promote the catalytic reaction.
Description
technical field [0001] The invention relates to the field of organic synthesis, in particular to a preparation method of α-GPC. technical background [0002] α-Glycerophosphatidylcholine, abbreviated as α-GPC or GPC, is a water-soluble metabolite naturally occurring in humans and animals, and is the product of the complete hydrolysis of two fatty acid chains on the phospholipid (PC) molecule. Pure GPC is transparent viscous or white powder, easy to absorb moisture in the air, highly soluble in water or methyl ethanol, almost insoluble in other solvents. GPC can be used as a choline supplement, which can stimulate the secretion of growth hormone in young people, and has a positive effect on memory ability, concentration and cognitive ability. [0003] GPC is a unique water-soluble phospholipid that naturally exists in the human body. It has important application value in the pharmaceutical and food industries. Especially in the health food boom in recent years, GPC has shown...
