Abstract

The invention discloses a preparation method for dendrobium candidum extract powder. The dendrobium candidum extract powder is prepared from dendrobium candidum by the steps: carrying out enzymolysis, alcohol extraction, concentration and drying. According to the preparation method disclosed by the invention, before alcohol extraction, enzymolysis is carried out on dendrobium candidum by a compound enzyme formed by cellulase, pectinase and papain, and the alcohol extraction method is assisted by the compound enzymolysis method, so that the purpose of improving the extraction efficiency and extraction rate is achieved. The preparation method is simple in process step, low in equipment requirement, strong in operability and suitable for industrial production.
