Embodiment 1

[0076] The preparation of salvia miltiorrhiza extract, the steps are as follows:

[0077] (1) Salvia miltiorrhiza medicinal materials are added with 5 times the amount of medicinal materials and 75% ethanol, refluxed for extraction for 2 hours, filtered to obtain the alcohol extract, and medicinal residue A is for use;

[0078] (2) Add 5 times the amount of water to medicinal residues A, decocted for 2 hours, filter to obtain water extract, and discard medicinal residues B;

[0079] (3) The alcohol extraction liquid in step (1) was stirred for 30 minutes, the temperature of the alcohol extraction liquid was lowered to below 15°C and left to stand for 12 hours, the supernatant liquid was drawn to obtain the alcohol extraction supernatant liquid, and the water extraction liquid in step (2) was stirred For 30 minutes, the temperature of the water extract was lowered to below 15°C and left to stand for 12 hours, and the supernatant was aspirated to obtain the water-extract superna...

Embodiment 2

[0084] The preparation of salvia miltiorrhiza extract, the steps are as follows:

[0085] (1) The medicinal materials of Salvia miltiorrhiza add twice the amount of medicinal materials and 50% ethanol, reflux for about 0.5 hours, and filter to obtain the alcohol extract.

[0086] (2) Add 2 times the amount of medicinal material to the above-mentioned medicinal residues A, decoct for about 0.5 hours, filter to obtain an aqueous extract, and discard the medicinal residues B;

[0087] (3) The alcohol extract in step (1) was stirred for 20 minutes, the temperature of the alcohol extract was lowered to below 15°C and left to stand for 6 hours, the supernatant was drawn to obtain the alcohol extract supernatant, and the water extract in step (2) was stirred For 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 drawn to obtain the water-extract supernatant;

[0088] (4) The supernatant of water extrac...

Embodiment 3

[0092] The preparation of salvia miltiorrhiza extract, the steps are as follows:

[0093] (1) The medicinal materials of Salvia miltiorrhiza are added with 7 times the amount of medicinal materials and 100% ethanol, refluxed for extraction for about 4 hours, filtered to obtain the alcohol extract, and the residue A is for use;

[0094] (2) The above-mentioned medicinal residues 1 are added with 7 times of the amount of medicinal materials, decocted for about 4 hours, filtered to obtain an aqueous extract, and the medicinal residues B are discarded;

[0095] (3) The alcohol extraction liquid in step (1) was stirred for 60 minutes, the temperature of the alcohol extraction liquid was lowered to below 15°C and left to stand for 24 hours, the supernatant liquid was drawn to obtain the alcohol extraction supernatant liquid, and the water extraction liquid in step (2) was stirred For 60 minutes, the temperature of the water extract was lowered to below 15°C and left to stand for 24 ...

Abstract

The present invention relates to a new salvia miltiorrhiza extract and its preparation. The preparation method of the salvia miltiorrhiza extract comprises the following steps: (1) extracting the salvia miltiorrhiza medicinal material with a lower alcohol, filtering to obtain the alcohol extract, and the dregs A for standby; (2) Add water to extract the dregs A, filter to obtain the water extract, and discard the dregs B; (3) The alcohol extract and the water extract are cooled and left to stand separately, and then the supernatants are respectively absorbed into the alcohol extraction supernatant, Water extraction supernatant; (4) Water extraction supernatant is concentrated to obtain water extraction concentrate; (5) Water extraction concentrate is gradually added to alcohol extraction supernatant, combined and concentrated to obtain a mixed concentrate; (6) After mixing and concentrating Add purified water to the liquid, combine and concentrate, and collect the cream to a certain concentration specific gravity, and obtain the salvia miltiorrhiza extract.

Description

technical field [0001] The invention relates to a method for extracting Chinese medicinal materials, in particular to an extract of traditional Chinese medicine Salvia miltiorrhiza and an extraction method. Background technique [0002] Salvia 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 Materia Medica" in the Eastern Han Dynasty. [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 active components of Salvia miltiorrhiza: one is the fat-soluble effective part represented by tanshinone; the other is the water-soluble effective part represented by salvianolic acid. In recent years, studies have sh...
