Embodiment Construction

[0013] The present invention will be further described below in conjunction with specific embodiments.

[0014] Take the propolis raw material, crush it and add it to distilled water, stir overnight at room temperature; after standing, filter, transfer the filter residue to a Soxhlet reflux extractor, first reflux with petroleum ether as a solvent for 6 hours to remove the beeswax; then use ethanol (or ethanol: ??? Acetone (mixed solvents in any proportion) is heated and refluxed for 12 hours, and the extract is distilled under reduced pressure to obtain refined propolis.

[0015] Comparative experiments show that the use of 3% L-lysine aqueous solution to dissolve the aforementioned refined propolis, or the use of a total of 3% L-lysine and L-arginine mixed aqueous solution to dissolve the aforementioned refined propolis can improve See Table 1 for the yield of water-soluble propolis products.

Abstract

The invention relates to a process for extracting active ingredients from bee glue and the use of the water-soluble bee glue product, wherein the extraction consists of disintegrating natural bee glue, chaging into water, sufficiently stirring, extracting through immersion, carrying out solid-liquid separation, subjecting the solid to backflow extraction with petroleum ether, distilling and seasoning, dissolving the obtained solid into aqueous solution of L-arginine or L-lycine, filtering liquid and subjecting the solution to freeze drying treatment.

Description

Technical field [0001] The invention relates to a method for extracting effective ingredients in propolis, in particular to a method for processing the effective ingredients in propolis to be water-soluble, and the use of such water-soluble propolis products. Background technique [0002] Propolis is a resinous substance prepared by chewing the resin secretions of plants and beeswax by bees. Propolis has a long history of application all over the world. In recent years, there have been many studies on the chemical composition, physiological and pharmacological effects of propolis at home and abroad, and it has been found that propolis has the effects of antibacterial, antiviral, anti-inflammatory, lowering blood lipids, lowering blood sugar and enhancing immunity. [0003] At present, propolis products at home and abroad basically obtain effective ingredients through alcohol extraction, but the alcohol extract of propolis is not easily soluble in water, has low absorption and uti...
