Methods for the Production of Sub-critical Water Extracts of Certain Plants with Healthcare Applications.

摘要

A methods of preparing an extract from medicinal plants of the Skullcap family comprises the grinding (or other tissue size reduction means) of the plants, extraction in sub-critical water preferably at 150-250 and 25-100 bar and cooling of the extract, to precipitate desirable flavonoids, followed by isolation by centrifugation or filtration. The sub-critical water extract may be similar in composition to those extracts obtained by means of methanol extractions. The resultant extract may be used to prepare medicinal capsules and drugs.
