Description

Пример 3. К 1,8 г неочищенного гуаиозниа , содержащего 1,49 г гуанозина и 0,1 г гуанина, добавл ют 60 мл дистиллированной воды, нагревают до 60°С с разбавленной серной кислотой, устанавливают рН 2,0, охлаждают до 20°С и через 30 мин отдел ют хроматографически чистый дигидрат гуанозина, на фильтре промывают этиловым спиртом и эфиром. Выход осаждени  гуанозина в пересчете на безводный гуанозин 85%, содерл ание основного вещества 100%.Example 3. To 1.8 g of unpurified guaiazia, containing 1.49 g of guanosine and 0.1 g of guanine, add 60 ml of distilled water, heat to 60 ° C with dilute sulfuric acid, adjust to pH 2.0, cool to 20 ° C and, after 30 minutes, the chromatographic guanosine dihydrate is separated, washed on the filter with ethyl alcohol and ether. The yield of precipitation of guanosine in terms of anhydrous guanosine 85%, the content of the basic substance 100%.
