METHOD OF PRODUCING GEL BASED ON WATER EXTRACTION FROM UNOSSIFIED ANTLERS Russian patent published in 2009 - IPC A61K35/32 A61K9/06 A61P17/02 A61Q19/00 

FIELD: beiotechnology.

SUBSTANCE: invention concerns production of items with expressed bioactivity and can be applied as healing and preventive medicine in medical cosmetology, balneology, medicine and veterinary. Method involves extraction of bioactive substances from unossified antlers at 40°C or lower temperature, conservation and gelatinisation agent addition to obtain aqueous solution of conservation agents represented by methylparaben and propylparaben. Extraction of bioactive substances is performed by conservation agent extraction to the solution by ultrasonic method in cavitation mode at weight ration of unossified antlers to aqueous solution of 1:1-10 for time period sufficient to obtain required extract concentration. Carbopol is used as gelatinisation agent and mixed with distilled water preliminarily and aged till imbibition, then neutralising agent is added in amount sufficient to form gel mass, further neutralised by adding citric acid solution to 6-7.5, and aqueous solution of unossified antlers and 1-30 wt % of water retentive component are added to obtained gel mass in portions with stirring.

EFFECT: obtaining high-quality gel based on aqueous solution of unossified antlers by ultrasonic extraction of bioactive substances.
