Abstract

Special extracts of grape berries and Gogi berries can be prepared by exposing fruit juices or preparations to an insoluble binding resin which is then extracted with soluble polyvinylpyrollidone. Grape and Goji extracts made in this way can be used to inhibit or control platelet aggregation. Grape extract has exceptional antibacterial properties and can be used to control oral bacteria and to control MRSA (Methicillin-resistant Staphylococcus aureus). The combination of control of platelet aggregation and antibacterial properties exhibited by the grape-extract allows it to be used to significantly extend the life of isolated platelets. When added to solutions of isolated platelets, the grape extract prevents bacterial growth and prevents deterioration of the platelets through activation. This treatment extends the usable life of platelet concentrates to at least ten days.
