Question

Please tell me the procedure for extraction of celery seeds?

Answer 1

The most simple extract of celery seeds is a tea or infusion:

about 1g freshly contused seeds are dashed with boiling water and let brew for 5-10 minutes.

For fluid-extract 1kg coarsely powdered celery seeds are percolated with a mixture of 900 ml ethanol 95% and 100 ml distilled water.

For dry extract see:

Essential oils are extracted by water steam distillation or  supercritical CO2 extraction
