Embodiment 1

[0077] The preparation of salvia miltiorrhiza extract, the steps are as follows:

[0078] (1) Salvia miltiorrhiza plus 5 times the amount of medicinal materials and 75% ethanol, reflux extraction for 2 hours, filter to obtain the alcohol extract, and dregs A for later use;

[0079] (2) Add 5 times the amount of medicinal materials to dregs A, decoct for 2 hours, filter to obtain water extract, and discard dregs B;

[0080] (3) Stir the alcohol extract in step (1) for 30 minutes, lower the temperature of the alcohol extract to below 15°C and let it stand for 12 hours to absorb the supernatant to obtain the alcohol extract supernatant, and stir the water extract in step (2) After 30 minutes, the temperature of the water extract dropped to below 15°C and stood still for 12 hours, and the supernatant was absorbed to obtain the water extract supernatant;

[0081] (4) Concentrate the water-extracted supernatant to a relative density of 1.20-1.30 to obtain a water-extracted concentr...

Embodiment 2

[0085] The preparation of salvia miltiorrhiza extract, the steps are as follows:

[0086] (1) Salvia miltiorrhiza plus 2 times the amount of medicinal materials and 50% ethanol, reflux extraction for about 0.5 hours, filter to obtain the alcohol extract, and dregs A for later use;

[0087] (2) Add 2 times the amount of medicinal materials to the above dregs A, decoct for about 0.5 hours, filter to obtain a water extract, and discard dregs B;

[0088] (3) Stir the alcohol extract in step (1) for 20 minutes, lower the temperature of the alcohol extract to below 15°C and let it stand for 6 hours to absorb the supernatant to obtain the alcohol extract supernatant, and stir the water extract in step (2) After 20 minutes, the temperature of the water extract was lowered to below 15°C and allowed to stand for 6 hours, and the supernatant was absorbed to obtain the water extract supernatant;

[0089] (4) Concentrate the water-extraction supernatant to a relative density of 1.20 to ob...

Embodiment 3

[0093] The preparation of salvia miltiorrhiza extract, the steps are as follows:

[0094] (1) Add 7 times the amount of Danshen medicinal materials and 100% ethanol, reflux extraction for about 4 hours, filter to obtain alcohol extract, and dregs A for later use;

[0095] (2) Add 7 times the amount of medicinal materials to the above dregs 1, measure water, decoct for about 4 hours, filter to obtain a water extract, and discard dregs B;

[0096] (3) Stir the alcohol extract in step (1) for 60 minutes, lower the temperature of the alcohol extract to below 15°C and let it stand for 24 hours to absorb the supernatant to obtain the alcohol extract supernatant, and stir the water extract in step (2) After 60 minutes, the temperature of the water extract was lowered to below 15°C and allowed to stand for 24 hours, and the supernatant was absorbed to obtain the water extract supernatant;

[0097] (4) Concentrate the water-extraction supernatant to a relative density of 1.30 to obtai...

Abstract

The invention relates to a new radix salviae milliorrhizae extract and preparation thereof. The preparation method of the radix salviae milliorrhizae extract disclosed by the invention comprises the following steps: (1) extracting a radix salviae milliorrhizae medicinal material by using lower alcohol, filtering the obtained product so as to obtain alcohol extracting liquid, and taking herb residues A for standby application; (2) adding water into the herb residues A to extract, filtering the obtained product so as to obtain water extracting liquid, and removing herb residues B; (3) respectively cooling and standing the alcohol extracting liquid and the water extracting liquid, and respectively sucking supernatants as an alcohol extracting supernatant and a water extracting supernatant; (4) concentrating the water extracting supernatant so as to obtain a water extracting concentrated solution; (5) gradually adding the water extracting concentrated solution into the alcohol extracting supernatant, and concentrating the obtained mixture, so that a mixed concentrated solution is obtained; and (6) adding purified water into the mixed concentrated solution, concentrating the obtained mixture until a certain concentration proportion is achieved, and collecting paste, so that the radix salviae milliorrhizae extract is obtained.

Description

technical field [0001] The invention relates to a method for extracting Chinese medicinal materials, in particular to an extract of the traditional Chinese medicine Salvia miltiorrhiza and the extraction method. Background technique [0002] Salvia miltiorrhiza Beg. is the dried root of Salvia miltiorrhiza Beg. In the treatment of coronary heart disease and angina pectoris in my country, it has been used for nearly a thousand years. It was first recorded in the "Shen Nong's Herbal Classic" in the Eastern Han Dynasty and listed as a top grade. [0003] Since the last century, with the continuous development of chemical separation methods and the quiet rise of modern phytochemistry, people have further studied the chemical components of Salvia miltiorrhiza. [0004] Studies have shown that there are two main types of active ingredients in Salvia miltiorrhiza: one is the fat-soluble active part represented by tanshinone; the other is the water-soluble effective part represente...
