【Echinacea purpurea herb dry extractExtraction Method】
1. Echinacea (EP) extract (4%) production process
Pulverize the original medicinal materials and extract with 70% ethanol under reflux. Aspirate the alcohol extract into the decompression and concentration tank, recover the ethanol to about 1/4 of the original volume (the recovered solution also contains 15% to 20% ethanol), centrifuge to obtain the centrifuged liquid, and concentrate it under reduced pressure to 15 ± 5 waves Beauty (thermal measurement), add an appropriate amount of auxiliary materials, mix evenly, spray dry, sieve, mix, and package to get finished product.
The yield of the product produced by this process is 24% to 25%, and the content of chicory acid is about 4%. It is suitable for the production of echinacea extract containing 4% of chicory acid.
