Известны способы получени  гпндарина, используемого в качестве седатпвпого средства , путем экстракции измельченных клубнеГ сладкой Стефании ксилолом, обработки экстракта серпой кислотой и подщелачиваии  аммиакомПо предлагаемому способу экстракт подщелачивают до рН 5,0, обрабатывают хлороформом , хлороформ упаривают, раствор ют осадок в метаноле, подкисл ют водным раствором сол пой кислоты и кристаллизуют хлоргидрат гиндарипа из метанола. Это позвол ет упростить технологию получени  гиндарииа и увеличить выход.Known methods for obtaining gpndarin, used as a sedative agent, by extraction of crushed tubers with sweet Stephenia xylene, treatment of the extract with sickle acid and alkalinization with ammonia. According to the proposed method, the extract is alkalinized to pH 5.0, treated with chloroform, chloroform evaporated, dissolved in a cream. with an aqueous solution of hydrochloric acid and hindap hydrochloride is crystallized from methanol. This allows us to simplify the technology of Hindaria and increase the yield.

Пример, {кг сухих измельченных клубней гладкой стефании смачивают 250 мл 10%-ного аммиака и заливают 10 л ксилола. Через 4 час экстракт сливают и добавл ют еще 8 л ксилола.Example, {kg dry crushed tubers of Stefania smooth are moistened with 250 ml of 10% ammonia and pour 10 liters of xylene. After 4 hours, the extract is decanted and another 8 liters of xylene is added.

Эту операцию повтор ют еще 3 раза, последний экстракт оставл ют дл  обработки свежей порции сырь . Из каждого экстракта извлекают алкалоиды двум  порци ми 10%-иой серной кислоты по 400 мл, оставл   вторую порцию кислоты дл  обработки следующего экстракта. Объединенную кислотную выт жку из четырех экстрактов подщелачивают аммиаком до рН 5,0 п извлекают гпндарин хлороформом (300, 300 и 200 мл). Хлороформенный раствор сушат над сульфатом иатрн  и хпаривают досуха. Остаток раствор ют в метаноле и добавл ют 1,5 объема сол пой кислоты (5%-ной). После охлаждени  выпавщий осадок хлоргидрата шидарина отдел ют, промывают гор чеГ смесью ацетона и метанола и кристаллизуют из 7-8-кратного количества метанола. Получают 14,6 гипдарпна из индийского сырь  и 13,6 г - из отечественного сырь . Т. ил. выше 250°С.This operation is repeated 3 more times, the last extract is left to process a fresh portion of the raw material. Alkaloids are extracted from each extract with two portions of 10% sulfuric acid, 400 ml each time, leaving a second portion of the acid to treat the next extract. The combined acid extract from the four extracts is made alkaline with ammonia to pH 5.0 and the gpdarine chloroform is extracted (300, 300 and 200 ml). The chloroform solution is dried over sulfate Iatrn and evaporated to dryness. The residue is dissolved in methanol and 1.5 volumes of hydrochloric acid (5%) are added. After cooling, the precipitated precipitate of shidarin hydrochloride is separated, washed hot with a mixture of acetone and methanol, and crystallized from a 7-8 fold amount of methanol. Get 14.6 gipdarpna from Indian raw materials and 13.6 g - from domestic raw materials. T. Il. above 250 ° C.
