Embodiment Construction

[0013] Below in conjunction with specific embodiment, further illustrate the present invention.

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

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 active ingredients in propolis, in particular to a method for converting the active ingredients in propolis into water-soluble ones, and the use of the water-soluble propolis products. Background technique [0002] Propolis is a resinous substance prepared by bees from the resinous secretions of plants collected and beeswax by chewing. Propolis has a long history of application all over the world. In recent years, there have been many studies on the chemical composition and physiological and pharmacological effects of propolis at home and abroad. It has been found that propolis has antibacterial, antiviral, anti-inflammatory, hypolipidemic, hypoglycemic, and immune-enhancing effects. [0003] At present, the active ingredients of propolis products at home and abroad are basically obtained through alcohol extraction, but the alcohol extract of propolis is not easy to dissolve in water, the absorption and...
