Embodiment 1

[0011] Add 30g of inosine and 1000ml of water into the reaction flask, raise the temperature to above 90°C, add S 2 o 8 2- / TiO 2 0.5g, and then keep warm for 3 hours, spot the plate to confirm that there is no inosine in the reaction. The temperature was lowered to room temperature, and the catalyst and hypoxanthine were filtered off. The liquid was concentrated under reduced pressure until anhydrous was distilled off, and dried to obtain 16.6 g of D-ribose, with a yield of 98.9%. It was confirmed by high performance liquid chromatography that the D-ribose has excellent related properties, as described in Table 1.

Embodiment 2

[0013] Add 30g of inosine and 1000ml of water into the reaction flask, raise the temperature to above 90°C, add S 2 o 8 2- / TiO 2 0.7g, and then incubated for 3 hours to confirm that there was no inosine in the reaction. The temperature was lowered to room temperature, and the catalyst and hypoxanthine were filtered off. The liquid was concentrated under reduced pressure until anhydrous was distilled off, and dried to obtain 16.5 g of D-ribose, with a yield of 98.3%. It was confirmed by high performance liquid chromatography that the D-ribose has excellent related properties, as described in Table 1.

Embodiment 3

[0015] Add 30g of guanosine and 1000ml of water into the reaction flask, raise the temperature to above 90°C, add S 2 o 8 2- / TiO 2 1.0 g, then incubated for 3 hours, and spotted to confirm that there was no inosine in the reaction. The temperature was lowered to room temperature, and the catalyst and guanine were filtered off. The liquid was concentrated under reduced pressure until anhydrous was distilled off, and dried to obtain 15.6 g of D-ribose, with a yield of 98.1%. It was confirmed by high performance liquid chromatography that the D-ribose has excellent related properties, as described in Table 1.

Abstract

The invention discloses a preparation method of D-ribose. In the preparation method, a super-strong solid acid catalyst is selected, and then nucleoside is hydrolyzed into the D-ribose and purine under the catalysis of the super-strong solid acid, wherein the D-ribose has a molecular formula of C4H9O4CHO, and the English name of the D-ribose is ribose; the molecule structural formula of the super-strong solid acid is as follows: S2O82 / TiO2; and the weight ratio of the super-strong solid acid to the nucleoside is 1-5:100. The hydrolysis reaction of the invention has the yield up to 98%-100%, and the method has less side reactions, less by-products and is easy to realize purification, thereby producing the D-ribose with high purity and high yield. The impurities are easy to be removed in the process of purifying the D-ribose, and the post-treatment difficulty is reduced.

Description

technical field [0001] The invention relates to the technical fields of food and medicine, in particular to a new method for preparing D-ribose. Background technique [0002] D-ribose is an important part of the genetic material nucleic acid in organisms, and it is in a pivotal position in the metabolism of nucleosides, proteins, and fats, and has important physiological functions and broad application prospects. D-ribose, as a natural component present in all cells in organisms, is closely related to the formation of adenosine and the regeneration of ATP, and is one of the most basic energy sources for life metabolism. It plays a key role in the metabolism of the heart and skeletal muscle, and can promote the recovery of ischemic tissue and local hypoxic tissue. Nucleic acid drugs are an important means for humans to treat viruses, tumors, and AIDS today. D-ribose is an important intermediate of many nucleic acid drugs and can be used for ribavirin, adenosine, thymidine, c...
