Extraction method of Eucommia extract

Eucommia extract is usually extracted by the following steps:

Crushing: First crush the bark or other parts of Eucommia ulmoides to increase the extraction efficiency.

Solvent extraction: Mix the crushed Eucommia material with a suitable solvent (such as ethanol, acetone, etc.) for extraction, usually by leaching or ultrasonic extraction.

Filtration: Filter the extracted solution through a filter such as filter paper to remove impurities and solid particles.

Concentration: Concentrate the filtered solution, usually by distillation, evaporation or reduced pressure concentration.

Crystallization or precipitation: Sometimes it is necessary to crystallize or precipitate the concentrated solution to obtain a pure Eucommia extract.

Drying: Finally, the obtained extract is dried to remove the remaining solvent to obtain the final Eucommia extract.
