Embodiment 1

[0134] a. Take 30 kg of Shengfu tablets, crush them, extract with 95% ethanol, extract 3 times (2 days each time), filter, combine the filtrates, recover the ethanol under reduced pressure to obtain the extract. The pH was adjusted to 3 with concentrated hydrochloric acid, extracted three times with ethyl acetate, the extracts were combined and concentrated under reduced pressure to obtain the oil fraction. Then adjust the pH to 9 with ammonia water, extract 3 times with ethyl acetate, combine the extracts, concentrate and dry under reduced pressure to obtain the total alkaloid fraction (about 128 g);

[0135] b. Pass the extract of the total alkaloid part through a neutral alumina column, elute with ethyl acetate, separate the crystalline samples, and combine the viscous samples together to obtain the total extract;

[0136] c. Put the total extract through alkalized silica gel column, elute with petroleum ether-ethyl acetate (1:1) and pure ethyl acetate, collect the ethyl ac...

Embodiment 2

[0138] a. Take 35 kg of Shengfu tablets, crush them, extract with 95% ethanol, extract 4 times (2.5 days each time), filter, combine the filtrates, recover the ethanol under reduced pressure to obtain the extract. The pH was adjusted to 5 with concentrated hydrochloric acid, extracted twice with ethyl acetate, the extracts were combined and concentrated under reduced pressure to obtain the oil fraction. Then adjust the pH to 10 with ammonia water, extract 3 times with ethyl acetate, combine the extracts, concentrate and dry under reduced pressure to obtain the total alkaloid fraction (about 145 g);

[0139] b. Pass the extract of the total alkaloid part through a neutral alumina column, elute with ethyl acetate, separate the crystalline samples, and combine the viscous samples together to obtain the total extract;

[0140] c. Pass the total extract through an alkalized silica gel column, elute with petroleum ether-ethyl acetate (1:1), pure ethyl acetate, collect the ethyl acet...

Embodiment 3

[0142] a. Take 20 kg of Sangfu tablets, pulverize them, extract with acid water, extract 3 times (2 days each time), filter, combine the filtrates, concentrate under reduced pressure to an appropriate volume, extract 3 times with ethyl acetate, combine the extracts and Concentrate under reduced pressure and dry to obtain the fat part. Adjust the pH to 9 with ammonia water, extract 3 times with ethyl acetate, combine the extracts, concentrate and dry under reduced pressure to obtain the total alkaloid fraction (about 80 g);

[0143] b. Pass the extract of the total alkaloid part through a neutral alumina column, elute with ethyl acetate, separate the crystalline samples, and combine the viscous samples together to obtain the total extract;

[0144] c. Pass the total extract through an alkalized silica gel column, elute with petroleum ether-ethyl acetate (1:1), pure ethyl acetate, collect the ethyl acetate eluate, and carry out recrystallization to obtain Fuziling (1220mg ).

Abstract

The invention relates to fuziline and a preparation method and an application of medicinal acid addition salt thereof. The fuziline has the structure of a formula (I) and can be applied to preparing the medicine for preventing and treating shock.

Description

technical field [0001] The invention belongs to the field of biomedicine, and in particular relates to the application of Fuziling and its pharmaceutically acceptable acid addition salts in the preparation of drugs for preventing and treating shock. Background technique [0002] Shock is an acute blood circulation disorder characterized by a sharp decrease in tissue perfusion after the body is subjected to strong harmful factors. Causes of shock include: blood and fluid loss, burns, trauma, infection, allergies, acute heart failure, and intense nerve irritation. A large amount of blood loss can cause hemorrhagic shock, which is common in acute hemorrhage such as traumatic hemorrhage, upper gastrointestinal bleeding, ruptured ectopic pregnancy, and postpartum hemorrhage. The occurrence of shock depends on the speed and amount of blood loss. When the blood loss is less than 10% of the whole blood within 15 minutes, the body can generally maintain stable blood pressure and tis...
