Bioactive serum fractions from fresh rose flowers and methods for their preparation and uses

A method for obtaining a bioactive serum fraction derived from fresh rose flowers (Rosa spp.) comprising the steps of cleaning, macerating, pressing and mechanical separation of fresh rose flowers to obtain an intracellular colloidal dispersion (ICD) and a fiber enriched material (fraction A);

• treatment A and mechanical separation of the intracellular colloidal dispersion to obtain supernatant A (cytoplasm/cytosol fraction) and a membrane fraction;
• (fraction B);
• treatment B and mechanical separation of the supernatant A to obtain supernatant B (cytosol fraction) and fraction C (cytoplasm fraction);
• and treatment C and mechanical separation of the supernatant of supernatant B to yield the serum fraction and a fraction D (precipitate), wherein no exogenous solvent or liquid is added prior or during separating steps.
