Embodiment 1

[0040] The preparation of embodiment 1 Echinacea purpurea extract

[0041] Take 2 kg of dried medicinal materials of Echinacea purpurea, crush them into 40 meshes, add 8 times the amount of 40% ethanol aqueous solution for reflux extraction for 0.5 hours, pour out the extract, add 10 times the amount of 10% ethanol aqueous solution for reflux extraction for 1 hour, and combine all the extracts, Concentrate under reduced pressure to 1 / 3 of the original volume, centrifuge at 4000r / min for 10min, pour out the supernatant, add 2 times the volume of the supernatant to dilute with deionized water, and filter the diluted solution through an organic membrane with a pore size of 300nm. The pressure is 0.2MPa, the operating temperature is 28°C, and 50L of the organic membrane permeate is obtained. The organic membrane permeate is separated by the ultrafiltration membrane. The membrane pore size is 10nm, and the operating pressure is 0.6MPa. The ultrafiltration membrane filtrate is then ...

Embodiment 2

[0042] The preparation of embodiment 2 Echinacea purpurea extract

[0043] Take 2 kg of dried medicinal materials of Echinacea purpurea, crush them into 40 meshes, add 10 times the amount of 50% ethanol aqueous solution for reflux extraction 3 times, each time for 0.5 hours, pour out the extract, add 10 times the amount of 10% ethanol aqueous solution for reflux extraction of the residue for 1 hour, Combine all the extracts, concentrate under reduced pressure to 1 / 3 of the original volume, centrifuge at 4000r / min for 10min, pour out the supernatant, add 2 times the volume of the supernatant to dilute with deionized water, and filter the dilution through an organic membrane first. The membrane pore diameter is 300nm, the operating pressure is 0.2MPa, and the operating temperature is 28°C to obtain 50L of organic membrane permeate, which is then separated by ultrafiltration membrane. Liquid 41L. The ultrafiltration membrane filtrate is then concentrated by nanofiltration membra...

Embodiment 3

[0044] The preparation of embodiment 3 Echinacea purpurea extract

[0045] Take 2 kg of dried medicinal materials of Echinacea purpurea, crush them into 40 meshes, add 12 times the amount of 50% ethanol aqueous solution for reflux extraction for 2 hours, pour out the extract, add 10 times the amount of 10% ethanol aqueous solution for reflux extraction for 1 hour, and combine all the extracts, Concentrate under reduced pressure to 1 / 3 of the original volume, centrifuge at 4000r / min for 10min, pour out the supernatant, add 2 times the volume of the supernatant to dilute with deionized water, and filter the diluted solution through an organic membrane with a pore size of 300nm. The pressure is 0.2MPa, the operating temperature is 28°C, and 50L of the organic membrane permeate is obtained. The organic membrane permeate is separated by the ultrafiltration membrane. The membrane pore size is 10nm, and the operating pressure is 0.6MPa. The ultrafiltration membrane filtrate is then c...

Abstract

The present invention discloses an echinacea purpurea extract. The echinacea purpurea extract comprises 2.4 to 3.1% of caftaric acid, 4.4 to 5.7% of chicoric acid and 1.5 to 2.0% of echinacoside based on the weight percentages of all ingredients accounting for the dry weight of the extract. The present invention also discloses a preparing method of echinacea purpurea extract and a detection method for phenols ingredient content in echinacea purpurea extract. The phenols ingredient content in the echinacea purpurea extract all meet the requirements of the active ingredient content specification of echinacea purpurea in United State Pharmacopeia 30 (USP 30). The phenols ingredient content is increased by 4 to 6% than that of echinacea purpurea extract sold on market. The preparing method has the advantages of simple technique, low cost, low energy consumption and easy industrialization.

Description

technical field [0001] The invention relates to a plant extract, a preparation method thereof and a detection method of components thereof, in particular to an echinacea purpurea extract, a preparation method thereof and a content detection method of phenolic components. Background technique [0002] Echinacea purpurea is a medicinal plant of the genus Echinacea in the family Asteraceae. It is native to the Americas and has been introduced in some areas of my country. The medicinal parts are roots, rhizomes or whole plants. Echinacea purpurea has a wide range of immune regulation functions, which can significantly improve the immune regulation level of the body. It is mainly used to treat colds (upper respiratory tract infections), typhoid fever, diphtheria, tuberculosis, insects, snake bites and other flowering root bacterial infections. In addition, Echinacea purpurea It also has antioxidant and anticancer effects. The main components of Echinacea include three categories...
