Embodiment 1

[0053] Embodiment 1: Preparation of Acanthopanax Acanthopanax Extract

[0054] (1) Extraction: extract 6 kg of Acanthopanax senticosus medicinal material 3 times with 12 volume times of water (72 L), extract for 1 hour each time, combine the extracts, concentrate to obtain Acanthopanax senticosus water decoction, and set aside;

[0055] (2) Primary alcohol precipitation: under stirring conditions, add 95% ethanol (to make the alcohol content reach 75%) to the Acanthopanax senticosus water decoction obtained in step (1), fully stir, and leave standstill for 6 hours; filter, and filtrate Recover ethanol until there is no alcohol smell, continue to concentrate until the relative density is 1.15 (measured at 80°C), and obtain a primary alcohol-precipitated paste of Acanthopanax acanthopanax extract, which is set aside;

[0056] (3) Lithium-sulfur method treatment: Take an appropriate amount of the alcohol-precipitated paste of the Acanthopanax senticosus extract obtained in step (...

Abstract

The invention relates to a low-toxicity acanthopanax injection and a preparation method thereof. The acanthopanax injection is prepared from the following active ingredients: 1.8-5.5mg / ml of total flavonoids, 0.13-0.70mg / ml of syringin, 0.06-0.34mg / ml of eleutheroside E and less than or equal to 800micro g / ml of potassium ions. The acanthopanax injection is low in content of potassium ions, which is reduced from less than or equal to 1000 micro g / ml in the national standard to lower than 800 micro g / ml (or counting at 800micro g / 5mg total flavonoids). The injection has the advantages of small abnormal toxicity and high safety. Animal experiments indicate that the tolerated concentration of a study subject is increased from 5mg / ml in the national standard to 18mg / ml. The abnormal toxicity inspection result on the low-toxicity acanthopanax injection provided by the invention is superior to the existing commercially available products.

Description

technical field [0001] The invention relates to Acanthopanax injection, in particular to a Acanthopanax injection with low toxicity. Background technique [0002] Acanthopanax is the dry root and rhizome or stem of Acanthopanax senticosus (Rupr. et Maxim.) Harms, a plant of Araliaceae. It has the effects of invigorating qi, invigorating the spleen, invigorating the kidney and calming the nerves. Sexually pungent, slightly bitter, warm. Acanthopanax injection is a sterilized aqueous solution made by extracting Acanthopanax senticosus. It is used to treat transient ischemic attack, cerebral arteriosclerosis, cerebral thrombosis, and cerebral embolism caused by liver and kidney deficiency. It is also used to treat coronary heart disease, angina pectoris combined with neurasthenia and menopausal syndrome. [0003] Chinese medicine injections including Acanthopanax injection, as a new dosage form of Chinese medicine produced by the development of modern science and technology...
