METHOD OF OBTAINING MEDICAL EXTRACT FROM BUCKTHORN FRUIT OR NATIVE RAW PELOID MATERIAL Russian patent published in 2009 - IPC A61K36/00 A61K35/02 A61P29/00 

FIELD: medicine.

SUBSTANCE: buckthorn fruit or native raw peloid material are ground and dehydrated to the loss of fluidity. Raw material extraction by vegetable oil and alcohol is performed twice in sequence using the same raw material portion. First extraction is performed with alcohol at the ratio of 1 kg of raw material per 1 l of alcohol in vacuum under pressure of 0.75-0.85 atmospheres at 2-3 degrees below alcohol boiling point without alcohol distillation for 1.5-2 hours, with constant stirring and further settling and drainage of alcohol extract. Second extraction is performed with vegetable oil at the ratio from 1 kg of raw material per 0.4 l of oil to 1 kg of raw material to 1 l of oil in vacuum under pressure of 0.75-0.85 atmospheres at up to 50°C with distillation of alcohol extract remaining after drainage and drainage of first oil extract portion. Third extraction is performed at the ratio of 1 kg from raw material per 0.4 l of oil to 1 kg of raw material per 1 l of oil, and from 1 kg of raw material per 0.5 l of alcohol to 1 kg of raw material per 1 l of alcohol in two stages: at atmosphere pressure with aging at 2-3°C below alcohol boiling point and constant stirring for 2-3 hours and further alcohol distillation in vacuum under pressure of 0.75-0.85 atmospheres. Obtained portions of oil extracts are drained into collector and mixed.

EFFECT: increased amount of extracted target product.
