PROCESS FOR THE PRODUCTION OF AN AESCIN-RICH CONCENTRATE OF ACTIVE MATERIAL FROM HORSE-CHESTNUT SEEDS

摘要

An aescin-rich extract is obtained by extracting comminuted horse chestnut seeds (not freed from fat) with a dilute aqueous acid (2% acetic or formic acid preferred), and then extracting the residue with a water-miscible alcohol or ketone or a mixture thereof with (80% methanol preferred). The thus-obtained extract may be concentrated to a solid, e.g. by vacuum drying.
