Description

Предметом изобретени   вл етс  способ получени  лагохилина из растени  Lagochilus inebrians путем экстракции сухого растени  дихлорэтаном .The subject of the invention is a method for producing lagochilin from a plant of Lagochilus inebrians by extracting a dry plant with dichloroethane.

Известный способ получени  лагохилина из растени  Lagochilus inebrians дает низкие выходы продукта (0,03% по весу сухого растени ).A known method for producing lagochilin from the plant Lagochilus inebrians produces low yields of the product (0.03% by weight of a dry plant).

Предлагаемый способ  вл етс  более простым и позвол ет получать более высокие выходы лагохилина (3% к весу сухого растени ).The proposed method is simpler and allows to obtain higher yields of lagoquilin (3% by weight of a dry plant).

Особенность способа заключаетс  в том, что экстрагирование лагохилина из воздушно-сухих листьев и стеблей растени  ведут гор чим дихлорэтаном в продол/кении 3 часов, после чего экстракт фильтруют и охлаждают; при этом выпадают кристаллы лагохилина, которые дополнительно промывают холодным дихлорэтаном дл  удалени  примесей, а полученный продукт перекристаллизовывают из гор чей воды или растворител .The peculiarity of this method is that the extraction of lagokhilin from air-dried leaves and plant stems is carried out with hot dichloroethane in a caul / Kenya for 3 hours, after which the extract is filtered and cooled; this gives rise to lagokhilin crystals, which are further washed with cold dichloroethane to remove impurities, and the product obtained is recrystallized from hot water or solvent.

Способ осуществл етс  следующим образом.The method is carried out as follows.

Высушенные и измельченные стебли и листь  растени  Lagochilus inebrlans кип т т с дихлорэтаном в течение 3 часов. Полученный экстракт отдел ют декантацией от основной части осадка, затем отфильтровывают от взвешенных частиц, после чего фильтрат оставл ют сто ть на сутки при комнатной температуре.The dried and ground stems and leaves of the Lagochilus inebrlans plant are boiled with dichloroethane for 3 hours. The extract obtained is separated by decantation from the main part of the precipitate, then filtered from the suspended particles, after which the filtrate is left to stand for a day at room temperature.

Вьшавщий кристаллический осадок отфильтровывают и промывают холодным дихлорэтаном дл  удалени  из него смол и окращенных примесей . После промывки осадок представл ет собой почти чистый лагохилин .The precipitated crystalline precipitate is filtered and washed with cold dichloroethane to remove gums and short impurities from it. After washing, the precipitate is almost pure lagohilin.

Полученный продукт перекристаллизовывают из гор чей воды или этилового спирта, или ацетона, в результате чего получают до 3 % (кThe resulting product is recrystallized from hot water or ethyl alcohol, or acetone, resulting in a gain of up to 3%

Предмет изобретени  1. Способ получени  лагохилина из растени  Lagochilus inebrians путем экстракции сухого растени  дихлорэтаном, отличающийс  тем, что экстрагирование лагохилина из воздущно-сухих листьев и стеблей растени  ведут гор чим дихлорэтаном в продолл ении 3 час., после чего фильтруют и охлаждают, причем выпавщие кристаллы лагохилина дополнительно промывают холодным дихлорэтаном дл  удалени  примесей, а полученный продукт перекристаллизовьгеают из гор чей воды или растворител .The subject matter of the invention 1. A method for producing lagokhilin from a plant of Lagochilus inebrians by extracting a dry plant with dichloroethane, characterized in that the extraction of lagochilin from air-dried leaves and stalks of the plant is carried out with hot dichloroethane for 3 hours, then filtered and cooled, and Lagohilin crystals are additionally washed with cold dichloroethane to remove impurities, and the resulting product is recrystallized from hot water or a solvent.

2. Применение полученного по п. 1 лагохилина в качестве кровеостанавливающего средства общего действи .2. Application of Lagokhilin obtained according to claim 1 as a hemostatic agent of general effect.
