Process for extracting 10-hydroxy-2-decenoic acid from royal jelly waste

Abstract

The invention discloses a process method for extracting 10-hydroxy-2-decenoic acid from royal jelly waste, wherein the process method comprises the following steps: (1) mixing the royal jelly waste with 95% edible alcohol according to the weight ratio of 1 to (8-10), adding the mixture into a reaction kettle, carrying out heating reflux for 40 minutes, then filtering while being hot, adding edible alcohol into the royal jelly waste, repeatedly extracting for 2-3 times, filtering, merging the filtrates, and carrying out reduced pressure recycling of ethyl alcohol; (2) concentrating the filtrate to 7-8 L, adding distilled water, heating to be transparent with steam, carrying out static filtration, washing the obtained crystal for three times with distilled water, and drying at the temperature of 50 DEG C, to obtain a crude product; and (3) adding a 50% methanol aqueous solution with the volume two times that of the crude product into the crude product, and recrystallizing for 3-4 times to obtain a 10-hydroxy-2-decenoic acid refined product. The process is simple, the cost is low, the 10-hydroxy-2-decenoic acid is extracted from the royal jelly waste, the maximum utilization rate of resources is achieved, the purity of the obtained 10-hydroxy-2-decenoic acid refined product reaches more than or equal to 99%, and the 10-hydroxy-2-decenoic acid can be used for production of antibacterial, anti-cancer and anti-radiation drugs.

Description

technical field [0001] The invention relates to the technical field of preparation methods of royal acid, in particular to a process for extracting royal acid from royal jelly residue. Background technique [0002] Royal acid has a wide range of pharmacological effects. It can enhance the body's resistance to physical, chemical and biological pathogenic factors, enhance the body's immune function, promote tissue repair, adjust endocrine and metabolic functions, and improve important organs. The function of antibacterial and inhibition of experimental tumor growth. Royal acid has a very good development prospect as a health food, and it will be more and more valued by people. It can be said that it provides the source of life for human health, which is really important. Non-standard clinical observation since 1995, it is really good for kidney failure, cholecystitis, diabetes, hyperlipidemia, senile diseases, menopausal disorders, low immune function, and promoting children'...
