METHOD FOR OBTAINING A COMPOSITION OF STIMULATING ACTION BASED UPON CAPSAICINOIDS (VARIANTS) Russian patent published in 2008 - IPC A61K36/67 

FIELD: medicine, veterinary science, cosmetology.

SUBSTANCE: the present innovation deals with manufacturing poisoning substances of lethality-free action as components of protective coverings. One should successively fulfill the extraction, distillation of the extragent's excess on ending the extraction, the drain of distilled extragent followed by the repeated distillation of extragent in rotor evaporators with subsequent centrifuging the extract obtained to obtain purified concentrate and mixture of lipophilic and hydrophilic fractions followed by separating the mixture of lipophilic and hydrophilic fractions due to acidification up to pH=4.5-5 followed by centrifuging and obtaining the end product in parallel both out of purified concentrate and out of lipophilic fraction, due to multiple recrystallization out of 4-fold excess of petroleum ether along with separating and drying end products and their uniting. Extraction should be carried out in extractor modules consisted of mutually connected an evaporator, and extractor and a condenser, moreover, the extractor is represented by two tanks inserted one into another, in the space between which the evaporation of extragent takes place or inside steam pipes (the first variants), or along the whole volume of inter-tank space (the second variant). The extractor and the evaporator are connected together due to a three-way valve. The efficiency of extracting the sum of capsaicinoids corresponds to about 90%. The innovation enables to increase the degree of extracting the target product out of raw material.

EFFECT: higher efficiency.
