Problems solved by technology

At present, Echinacea purpurea is used as an immunostimulant and immunomodulator in the Americas for the treatment of acute or chronic respiratory tract infections caused by viral diseases or bacteria, adjuvant treatment of various antibiotics and various serious bacterial infections, etc., and the real medicinal effect is the polysaccharide , cichoric acid and flavonoids and other active ingredients, most of them are easily soluble in organic solvents such as water and ethanol, but organic solvents pollute the environment, and there are many inconveniences in recycling, and water is used as an extraction solvent. It can greatly save the cost of use and is suitable for industrial production

Embodiment

[0022] Take 20 grams of Echinacea purpurea medicinal material as raw material, put it in a round bottom flask, add 20 times (ie 400ml) distilled water, place it on an electric heating mantle, keep it in a slightly boiling state for reflux extraction for 1.5 hours, after filtering, collect the filtrate. The filtrate was concentrated and evaporated to dryness in a water bath at 100°C to obtain the extract, which was placed in a vacuum drying oven and dried under vacuum at 60°C to obtain the active ingredient extract of Echinacea purpurea.
