    • Claim:
      1. A process for obtaining an extract rich in rosmarinic acid and semi synthetics derivatives from the plant Origanum vulgare, comprising: a) drying aerial parts, leaves, and branches of Origanum in a greenhouse with warm circulating air at 40° C. to produce dried material, b) grinding the dried material in knife mills to produce powder, c) extracting at least part of the powder with water/acetic acid solvent mixture (85:15 v/v) for 7 days, d) lyophylization of aqueous extract, treating the water/acetic acid solution (85:15 v/v) with calcium hydroxide for separation of the extract rich in rosmarinic acid (RA) as a solid.
