Description
В основном авт. св. № 71377 описан снособ выделени алкалоидов из безвременника, заключающийс в том, что исходное сырье экстрагируют водой, иосле чего из водной выт жки извлекают алкалоид колхицин известиыми приемами органическим растворителем.Basically auth. St. No. 71377 described the removal of alkaloids from the autumn crocus, which consists in extracting the raw material with water, and then extracting the alkaloid colchicine from the water extract with organic solvent.
Предлагаемый способ вл етс дальнейшим усовериюнствованием извсст 1ого способа, позвол ющим исключить образование эмульсии при переработке водной выт жки.The proposed method is a further improvement of the conventional method, which makes it possible to eliminate the formation of an emulsion during the processing of aqueous extract.
Особенность способа заключаетс р том, что нз водной выт жки исходного сырь алкалоиды осаждают вместе с белками.The peculiarity of the method lies in the fact that, with the water extraction of the raw material, alkaloids are precipitated together with proteins.
П р и м ер. К 4 кг измельченных свежих клубиелуковиц безвременника добавл ют раетвор 40 г сульфита натрн в 250 мл воды. Смесь отжимают . Остаток смен1ивают с 2 л воды и снова отжимают. Р1звлечение водой повтор ют еще один раз.P r and m er. To 4 kg of crushed fresh strawberry bullets of autumn crocus are added a splitter of 40 g of sodium sulphite in 250 ml of water. The mixture is wrung out. The residue is changed from 2 liters of water and squeezed out again. P1 water is repeated one more time.
К полученным водным выт жкам прибавл ют сульфа-i- аммони до прекраиюни вынаде1н- белка. Белковую массу отфильтровывают и после отжимани на нутче извлекают изопропиловым ениртом. Спиртовой экетракт упаривают.Sulfa-i-ammonium is added to the resulting aqueous extracts to discontinue the n-protein. The protein mass is filtered and, after pressing, the mixture is extracted with isopropyl yenert. Alcohol echektract evaporated.
После соответствуюид,ей обработки остатка получают 1,05 г колхамина и 7,52 г колхнцина.After the corresponding treatment, the residue is treated with 1.05 g of colchamine and 7.52 g of colchicine.
