Description
Обычно примен емые в медицине, водные, спиртовые и водно-спиртовые извлечени лекарственных растений имеют р д существенных недостатков , главным из которых вл етс наличие в этих извлечени х большого количества балластных веществ.Commonly used in medicine, water, alcohol and water-alcohol extracts of medicinal plants have a number of significant drawbacks, the main of which is the presence in these extracts of a large number of ballast substances.
С другой стороны, в практике лекарственного дела ощущаетс больша необходимость замены настоек и отваров жидкими или сухими концентратами , содержащими сумму действующих начал в минимальном объеме.On the other hand, in the practice of medicine, there is a great need to replace infusions and decoctions with liquid or dry concentrates containing the sum of the active principles in a minimum amount.
Эти обсто тельства вызывают необходимость выработки такой методики работы, при которой концентрирование растительного извлечени не привело бы к потере действующих начал растени , и при которой в концентрат попало бы минимальное количество балластных веществ из растени .These circumstances necessitate the development of such a method of operation in which the concentration of the plant extract would not lead to the loss of the active principles of the plant and in which the minimum amount of ballast substances from the plant would fall into the concentrate.
При обычно примен емом методе извлечени действующих начал из цветов ландыша этиловым спиртом концентрат, полученный таким путем, содержит, правда, почти все количество заключавшихс в цветах действующих начал, но нар ду с этим также большое количество балластных веществ.In the commonly used method of extracting the active principles from the flowers of the lily of the valley with ethyl alcohol, the concentrate obtained in this way contains, however, almost the entire amount of the active principles contained in the flowers, but also a large amount of ballast substances.
В противоположность этому, согласно предлагаемому изобретению, получаемый концентрат содержит также всю сумму действующих начал ландыша, но при этом совершенно ничтожное количество балластных веществ.In contrast, according to the invention, the resulting concentrate also contains the entire amount of the active principles of the lily of the valley, but a completely insignificant amount of ballast substances.
Способ этот заключаетс в следующем . Воздушно - сухие цветы ландыша экстрагируютс при подогреве смесью хлороформа с небольшим количеством (около 5%) этилового 96/о-го спирта. Затем, от полученной выт жки отгон етс больша часть растворител и остаток обрабатываетс небольшим количеством спирта и воды. Оставшиес хлороформ и спирт отгон ютс , а полученна водна выт жка отфильтровываетс от нерастворившегос остатка.This method is as follows. Air - dried flowers of the lily of the valley are extracted by heating with a mixture of chloroform with a small amount (about 5%) of ethyl 96 / o-alcohol. Then, most of the solvent is distilled off from the obtained extract and the residue is treated with a small amount of alcohol and water. The remaining chloroform and alcohol are distilled off, and the resulting aqueous extract is filtered off from the insoluble residue.
Вес полученного концентрата оставл ет около 1,5°/о от веса вз тых воздушно сухих цветов ландыша и содержит, как показывает биологическа проверка, всю сумму действующих начал растени .The weight of the concentrate obtained leaves about 1.5% of the weight of the taken dry air flowers of the lily of the valley and contains, as the biological test shows, the entire amount of the active principles of the plant.
Дл получени сухого концентрата водный раствор упариваетс до небольшого остатка, смешиваетс обычным образом с молочным сахаром и смесь высушиваетс .To obtain a dry concentrate, the aqueous solution is evaporated to a small residue, mixed in the usual way with milk sugar, and the mixture is dried.
