Embodiment 1

[0043] The preparation of embodiment 1 crude drug extract of the present invention

[0044] Take 10g of Salvia miltiorrhiza, Pueraria lobata and Chuanxiong each (1:1:1), mix well, add 300mL of 95% v / v ethanol, heat to reflux for 1h, filter the extract, recover ethanol from the filtrate and concentrate to an appropriate amount. Add 300 mL of 50% v / v ethanol to the dregs, heat and reflux for 1 hour, filter the extract, recover ethanol from the filtrate and concentrate to an appropriate amount. Add 300 mL of water to the dregs, decoct for 2 hours, filter the decoction, evaporate to dryness, and combine the three extracts to obtain the crude drug extract of the present invention.

Embodiment 2

[0045] The preparation of embodiment 2 crude drug extracts of the present invention

[0046] Take 10g of Salvia miltiorrhiza, Pueraria lobata and Chuanxiong each (1:1:1), mix well, add 400mL of 70% v / v ethanol, heat to reflux for 1h, filter the extract, recover ethanol from the filtrate and concentrate to an appropriate amount. Add 300 mL of 40% v / v ethanol to the dregs, heat and reflux for 1 hour, filter the extract, recover ethanol from the filtrate and concentrate to an appropriate amount. Add 300 mL of water to the dregs, decoct for 2 hours, filter the decoction, evaporate to dryness, and combine the three extracts to obtain the crude drug extract of the present invention.

Embodiment 3

[0047] The preparation of embodiment 3 crude drug extracts of the present invention

[0048] Take 10g of Salvia miltiorrhiza, Pueraria lobata and Chuanxiong each (1:1:1), mix well, add 200mL of 85% v / v ethanol, heat to reflux for 1h, filter the extract, recover ethanol from the filtrate and concentrate to an appropriate amount. Add 200 mL of 60% v / v ethanol to the dregs, heat and reflux for 1 hour, filter the extract, recover ethanol from the filtrate and concentrate to an appropriate amount. Add 200 mL of water to the dregs, decoct for 2 hours, filter the decoction, evaporate to dryness, and combine the three extracts to obtain the crude drug extract of the present invention.

Abstract

The invention provides a Tongmai oral liquid raw material extract, which is characterized in that the ratio of Tongmai oral liquid raw materials is as follows: salvia miltiorrhiza: radix puerariae: ligusticum wallichii=1: 1: 1, and in the raw material extract, the weight ratio of the active ingredients is as follows: tanshinol: puerarin: ferulic acid: tanshinone IIA=(0.9-1.3): (1.0-1.3): (1.0-1.2): 1.0. According to the invention, alcohol and water are taken as solvents to extract the Tongmai oral liquid raw materials together; although the extraction efficiency for the active ingredients is not as good as extraction by using 60% alcohol, the raw material extract prepared by the method is obviously superior to the previous preparation process and the 60% alcohol extract with the highest active ingredient content in pharmacological activity; an unexpected technical effect is achieved; and the Tongmai oral liquid raw material extract is advantageous for the patients suffering cardiovascular and cerebrovascular diseases.

Description

technical field [0001] The invention relates to an extract of raw materials of Tongmai Oral Liquid and its preparation method and application. Background technique [0002] Tongmai Oral Liquid is composed of Danshen, Chuanxiong, and Pueraria lobata. The twentieth volume of the Ministry of Pharmaceutical Standards for Traditional Chinese Medicine Prescriptions.
