(5) СПОСОБ ПОЛУЧЕНИЯ ФЛАВОНОИДОВ(5) METHOD FOR OBTAINING FLAVONOIDS
Изобретение относитс к химикофармацевтической промышленности и ка саетс получени лекарственных препаратов„ Известен способ получени флавоно . идов путем экстракции сырь этиловым спиртом, гидролиза и хроматографйровани tl. Однако известный способ вл етс трудоемким, не обеспечивает полный выход флавоноидов. Цель изобретени - расширение сыр евой базы и упрощение способа. Поставленна цель достигаетс тем что в качестве источника сырь испол зуют листь змееголовника сибирского (Dracocephalun nutans L), которые экстрактируют 70%-ным этиловым спиртом , далее гидролизат охлаждают до 0-3 С и хроматографирование провод т на полиамидном геле. Способ осуществл етс следующим образом. 100 Г воздушно-сухих листьев змееголовника сибирского (Dracocephalun nutans L) исчерпывающе экстрагируют этанолом при нагревании на вод ной бане. Полученный экстракт сгущают под вакуумом и оставшеес водное извлечение (100 мл) очищают экстракцией хлороформом. К полученному сгущенному и очищенному водному экстракту змееголовника сибирского добавл ют 3 г ферментного препарата Пектаваморин Г 10х и инкубируют в термостате при . По ходу инкубации провер ют полноту гидролиза методом двумерной бумажной хроматографии в системах растворителей бутанол-лед на уксусна кислота-вода (4:1:5) и 15%-а уксусна кислота, про вл флавоновые агликоны в УФ-свете. Полнота гидролиза достигаетс через 48 ч. При этом в гидролизате установено наличие флавоноидов.The invention relates to the chemical and pharmaceutical industry and relates to the preparation of drugs. A method for the production of flavono is known. ides by extraction of the raw material with ethyl alcohol, hydrolysis and chromatography tl. However, the known method is laborious, does not provide a complete yield of flavonoids. The purpose of the invention is to expand the raw material base and simplify the process. The goal is achieved by using the Siberian serpentine leaves (Dracocephalun nutans L) as a source of raw material, which are extracted with 70% ethanol, then the hydrolyzate is cooled to 0-3 ° C and chromatographed on a polyamide gel. The method is carried out as follows. 100 g of air-dry leaves of the Siberian serpentine head (Dracocephalun nutans L) are exhaustively extracted with ethanol when heated in a water bath. The extract obtained is concentrated under vacuum and the remaining aqueous extract (100 ml) is purified by extraction with chloroform. To the obtained condensed and purified aqueous extract of the Siberian snakehead was added 3 g of the enzyme preparation Pektavamorin G 10x and incubated in a thermostat at. In the course of incubation, the completeness of hydrolysis was checked by two-dimensional paper chromatography in the butanol-ice solvent systems for acetic acid-water (4: 1: 5) and 15% acetic acid, showing the flavone aglycones in UV light. The completeness of hydrolysis is reached after 48 hours. At the same time, the presence of flavonoids is established in the hydrolyzate.
