Description
: 3 ют водой, бер половинный объем воды от объема ксилола. Ксилольные растворы перемешивают с водой 15-20 мин при комнатной температуре и отдел ют слои на делительной воронке.5 Из ксилольного экстракта соласодин выдел ют известным способом. 4,81 г технического соласодина кип т т с 34 мл 50%-ного изопропилового . спирта (1:7 к весу технического соласодина) 30 мин, после чего охлаждают10 в воде со льдом при +5-0°С 30 мин и отфильтровывают . На фильтре соласодин 3 раза промывают 20%-ным изопропиловым спиртом по 4,8 мл (1:1 к весу технического соласодина ). Очищенный соласодин сушат при15 70-75°С. Получают 4,4 г соласодина с т. пл. 196,0-197,5°С. Выход на стадии гидролиза 4 гликоалкалоидов и выделени соласодина 87,2%. Выход 100%-ного соласодина на содержание его в траве - 45,33%. Предмет изобретени Способ получени соласодина из паслена дольчатого путем извелечени гликоалкалоидов , гидролиза их, экстракции соласодина органическим растворителем и очистки, отличающийс тем, что, с целью упрощени технологии производства, из свежего растительного сырь выдел ют сок, обрабатывают его раствором аммиака, после гидролиза осадок нагревают, добавл ют едкий натр с последующей обработкой известными методами. : 3 are boiled with water, taking half the volume of water from the volume of xylene. The xylene solutions are mixed with water for 15–20 minutes at room temperature and the layers are separated on a separatory funnel. 5 From the xylene extract, solasodine is isolated in a known manner. 4.81 g of technical salt is boiled with 34 ml of 50% isopropyl. alcohol (1: 7 to the weight of a technical solasodine) for 30 minutes, then cooled 10 in ice-water at + 5-0 ° C for 30 minutes and filtered. On the filter, solasodin is washed 3 times with 20% isopropyl alcohol, 4.8 ml each (1: 1 by weight of technical solasodine). Purified solasodine dried at 15 70-75 ° C. Obtain 4.4 g of salt with m. Pl. 196.0-197.5 ° C. The yield at the stage of hydrolysis of 4 glycoalkaloids and the release of solacodine is 87.2%. The output of 100% solasodina on the content of it in the grass - 45.33%. The subject of the invention. A method for producing solasodine from lozenge nightshade by extracting glycoalkaloids, hydrolyzing them, extracting solasodine with an organic solvent and purification, characterized in that, in order to simplify the production technology, juice is extracted from fresh plant raw material, treated with ammonia solution, and after hydrolysis the precipitate is heated caustic soda is added followed by treatment with known methods.
