【Product Name】: propolis extract propolis flavonoids
【English name】: Propolis Extract
【Source】: Honeybees from the plant spores or tree stems collected on the resin (gum), mixed with its upper palate gland, wax gland secretions processed from an aromatic smell of colloidal solids.
Chemical composition: flavonoids, terpenoids, organic acids, aromatic aldehydes and a variety of amino acids, vitamins, minerals and so on.
【Properties】: Propolis at room temperature is a jelly-like solid, was brown, tan, turquoise and black. With aroma Insoluble in water, soluble in ethanol, soluble in ether, chloroform.
[Packing] large cargo 25 kg / cardboard drum, sample packaging foil bag 1KG / bag, according to the requirements of labeling, if not required, generally by the company's internal label unified template paste.
Storage conditions This product should be sealed light, stored in a dry, cool, well-ventilated place.
Methylene chloride method
Remove the frozen ground propolis, add a certain amount of dichloromethane, stir, heat reflux, set aside for several hours, filtered, and then allowed to evaporate the solvent, the ethanol was heated to reflux extraction, filtration, to the wax can be Bee propolis extract.
2. Ethyl acetate method
According to the principle of similar compatibility of polar molecules, the use of ethyl acetate to dissolve propolis, the formation of extract-like. After standing for a few hours, and then the mass fraction of 5% NaHCO3 solution was extracted to give propolis ethyl acetate extract and propolis acid, and then acidified with hydrochloric acid propolis acid, first extracted with ether, and then extracted with ethyl acetate (N-butanol extract was obtained). The total amount of effective extract of propolis extracted with ethyl acetate was up to 57.8%, and the total flavonoid content in n-butanol extract was up to 22.5%.
3. Boron polymer electrolyte method
The anionic polymer - boron polymer electrolyte dilution of the refined aqueous solution and the cellulose containing propolis is fully mixed, dilute refined polymer electrolyte solution can be continuously dissolved propolis, and then add ethanol and seaweed as raw material Of the cellulose, which can extract the active ingredient-containing hydrophilic gel, the refined crystals have a strong antibacterial force, and the extract obtained by this method has good activity.
