Embodiment 1

[0030] Take Aconitum coreanum (Lèvl.) Rapaics dry root tuber powder 500g, reflux extraction with 95% ethanol twice, recover the extract to obtain 84g extract, add 2% hydrochloric acid to acidify to pH4, and extract three times with ethyl acetate to obtain The extract A and the sour water mother liquor, the sour water mother liquor was basified with ammonia water to pH 10, and then extracted 3 times with ethyl acetate to obtain the extract B and the sour water mother liquor, the extract B was concentrated to obtain 23 g of extract, and the extract Add it to the treated D605 macroporous adsorption resin column, elute with water and 80% ethanol successively, collect the ethanol eluate, and distill to dryness under reduced pressure to obtain 15 g of total alkaloid extract.

Embodiment 2

[0032] Take Aconitum coreanum (Lèvl.) Rapaics dry root tuber powder 600g, methanol reflux extraction 3 times, recover the extract to obtain 95g extract, add acetic acid to acidify to pH3, extract 2 times with chloroform to obtain extract A and jellyfish The sour water mother liquor was basified with sodium carbonate to pH 11, and then extracted 3 times with chloroform to obtain the extract B and the alkaline water mother liquor. The extract B was concentrated to obtain 35 g of extract, which was added to the treated D140 On a macroporous adsorption resin column, eluted with water and methanol in sequence, collected the methanol eluate, and distilled to dryness under reduced pressure to obtain 24 g of total alkaloid extract.

Abstract

On the basis of not reducing the drug effect, in order to make the most of utilizing monkshood resources of our country, through investigation, have separated and got total alkaloid extracts from monkshood, among them the content of alkaloid is more than 50 percent. The basis of medicine is Guan-Fu base or homolog equal activity even stronger, making the extact of monkshood total alkaloid to agents has offered an anti-arrhythmia medicine which is cheap, safety, take medicine handy for clinic; pharmacology experiment has improved it.

Description

[0001] purpose of invention [0002] On the basis of not reducing the efficacy, in order to make full use of the existing resources of Guanbaifu in my country, after research, the total alkaloid extract was isolated from Guanbaizhong, in which the alkaloid content was over 50%, and the main component was Guanfujia The preparation of the total alkaloid extract of Guanbaifu can provide low-cost, safe, effective, and convenient antiarrhythmic drugs for clinical use; the pharmacological experiments have preliminarily studied the effect of the total alkaloid extract. Antiarrhythmic effect. Background technique: [0003] Guanbaifu total alkaloid extract is the first effective part in my country to extract from Aconitum coreanum (Lèvl.) Rapaics root Guanbaizhong with a total alkaloid content greater than 50%; Guanbaifu is a commonly used traditional Chinese medicine, modern pharmacology Scientific studies have shown that the main components of Guanfuzhong, Guanfujia, Guanfuheptadin, Gu...
