process of extract concentration of propolis for nanofiltracao and product obtained for such process
NOVELTY – Concentrated extract preparation involves using Propolis and solvent to obtain extract and then filtering the extract by nanofilter, where the nanofilter is a permeable membrane that filters the materials according to molecular weight cutoffs. USE – Method for preparing concentrated extract (claimed) used in medicine and cosmetics industry. ADVANTAGE – The method provides the concentrated extract with 100% flavonoids in aqueous solution and 94% flavonoids in alcoholic solution at low temperature on large scale, where the concentrated extract has anti-bacterial, anti-oxidant, anti-fungal and anti-carcinogenic effects.
Main Application Field
B04 (Natural products and polymers. Including testing of body fluids (other than blood typing or cell counting), pharmaceuticals or veterinary compounds of unknown structure, testing of microorganisms for pathogenicity, testing of chemicals for mutagenicity or human toxicity and fermentative production of DNA or RNA. General compositions.); D21 (Preparations for dental or toilet purposes – including filling alloys, compositions for dentures or dental impressions, anti-caries chewing gum, plaque disclosing compositions, toothpastes, cosmetics, shampoos, topical anti-sunburn compositions and toilet soaps (A61K).); J01 (Separation – including evaporation, crystallisation, solvent extraction, chromatography, dialysis, osmosis including drying gases and/or vapours, and separation of solids from gases, liquids and other solids. Isotope separation, filter materials (including molecular sieves for separation), and centrifuges (except where used for analysis) (B01D, B03, B04, B07B).)
