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.
