Embodiment Construction

[0015] The method of the present invention and the test results of related applications are explained in detail below.

[0016] 1. Extraction method of propolis

[0017] Take fresh propolis, put it in distilled water (W / W=1:20) and stir at room temperature for 48 hours after crushing; filter; add water to the filter residue and repeatedly extract and filter; combine the filtrates and centrifuge at 15,000rpm for 60 minutes;

[0018] The supernatants were combined; the water-soluble propolis fraction was obtained after freeze-drying.

[0019] It has been determined that the extracted water-soluble propolis contains three flavonoid components, see attached figure 1 . figure 1 It is the result of thin-layer scanning of flavonoids in propolis water extract under visible light wavelength, and the color developer used is 5% ferric chloride-ethanol solution.

[0020] Two, the use research of propolis extract of the present invention

[0021] Experimental methods and conditions:

Abstract

A process for extracting the water-soluble active component of propolis features that it is extracted in water. Said extract can be used for preparing coronary artery dilators and phytoestrogenic medicines.

Description

technical field [0001] The invention relates to a method for extracting active ingredients in propolis and the application of the active ingredients. More precisely, the present invention relates to a method for extracting the water-soluble components of propolis and the proposed use of the water-soluble components of propolis. Background technique [0002] Propolis is a resinous substance made by bees from the resinous secretions and beeswax of plants collected and chewed. The composition of propolis is extremely complex. In recent years, there have been many research reports on the chemical composition, biological effects and pharmacological effects of propolis at home and abroad. Studies have found that propolis has antibacterial, antiviral, anti-ulcer, anti-inflammatory, local anesthetic, lowering blood pressure, and enhancing immunity effects. For active ingredient in propolis, in the prior art, concentrate on the organic solutions such as alcohol and ether to extract...
