Embodiment 1

[0086] (1) The prescription of raw material medicine is: Kudiezi 1000g.

[0087] (2) Take Kudiezi medicinal material, crush it through a 40-mesh sieve, add 7 times the amount of 70% ethanol, and extract it twice with 20KHz frequency ultrasound, the first time is 30 minutes, the second time is 20 minutes, the extract is filtered, combined, and the ethanol is recovered under reduced pressure. Get bitter dish extract.

[0088] (3) Add an appropriate amount of distilled water to the Kudiezi extract to make the liquid contain 1g of crude drug / ml, stir well, place it in the refrigerator overnight, centrifuge at high speed, take the supernatant for ultrafiltration, absorb the ultrafiltrate on a polyamide resin column, and wash with water until The effluent was colorless, and then eluted with 4 times the column volume of 70% ethanol. The 70% ethanol eluate was combined, and the ethanol was recovered under reduced pressure and concentrated to obtain 6.0 g of Kudiezi extract.

Embodiment 2

[0092] (1) The prescription of raw material medicine is: Kudiezi 1000g.

[0093] (2) Take Kudiezi medicinal material, crush it through a 30-mesh sieve, add 8 times the amount of 70% ethanol, and extract it twice with 20KHz frequency ultrasound, the first time is 30 minutes, the second time is 20 minutes, the extract is filtered, combined, and the ethanol is recovered under reduced pressure. Get bitter dish extract.

[0094] (3) Add an appropriate amount of distilled water to the Kudiezi extract to make the liquid contain 1g of crude drug / ml, stir well, place it in the refrigerator overnight, centrifuge at high speed, take the supernatant for ultrafiltration, absorb the ultrafiltrate on a polyamide resin column, and wash with water until The effluent was colorless, and then eluted with 5 times column volume of 75% ethanol. The 75% ethanol eluate was combined, and the ethanol was recovered under reduced pressure and concentrated to obtain 6.5 g of Kudiezi extract.

Abstract

The invention discloses a freeze dried injection of seeding of autumnal sowthistle-leaf ixeris and preparation method, wherein the injection is prepared from seeding of autumnal sowthistle-leaf ixeris extract and medicinal adjuvant, the preparation consists of ultrasonic extraction, high speed centrifuging and ultrafiltrating the extract, disintegrating and purifying with polyamide resin columns.

Description

Technical field [0001] The invention belongs to the technical field of traditional Chinese medicine pharmacy, and in particular relates to a Kudiezi freeze-dried powder injection and a preparation method thereof. Background technique [0002] Kudiezi, also known as Kudian Kusao, is the dry whole herb of the plant of Compositae. Bitter, pungent and flat in nature, it has the effects of clearing away heat and detoxification, reducing swelling and relieving pain. Its main components are flavonoid glycosides and adenosine. Modern studies have proved that the drug has the effects of increasing coronary blood flow and improving myocardial circulation in the circulatory system, and can significantly inhibit platelet aggregation and significantly increase the activity of fibrinolytic enzymes in the blood system. The marketed preparation is Kudiezi Injection (WS-10354(ZD-0354)-2002). Kudiezi Injection has the effects of promoting blood circulation, relieving pain, clearing away heat...
