Description
Technical Field
The invention belongs to the technical field of biological medicines, and particularly relates to a propolis extract and a preparation method and application thereof.
Background
Propolis is a natural adhesive substance prepared by mixing the resin secreted by young buds and callus of poplar, willow, pine and other plants with the secretion of jaw gland, wax gland and other plants. The Chinese and foreign research results show that the propolis has pharmacological effects of resisting oxidation, bacteria, inflammation, viruses, tumors and radiation, removing free radicals, promoting tissue regeneration, assisting in reducing blood sugar and blood fat and the like as a natural medicine and a health-care product with long application history, and the flavonoid compound with wide biological activity is a large class of compound with highest content and most abundant types in the propolis, and the content and the types of the flavonoid compound are incomparable with other natural products.
The biological activity of propolis is the result of the interaction of its various chemical components. However, the chemical components of propolis are extremely complex, and more than 300 components are known at present, including resin, beeswax, flavone, polyphenol, terpene, esters, volatile oil and the like, and are affected by plant sources, bee species and other factors, which brings great difficulty to separation and purification and research and application of active ingredients in propolis, and causes a problem that the content of active ingredients such as flavonoid compounds in propolis extract is relatively low, for example: the content of poplar can be as low as 2%, galangin can be as low as 1%, caffeic acid phenethyl ester can be as low as 0.5%, etc. Meanwhile, the preparation process reported in the prior literature has the advantages that the total flavonoids in the propolis with high content are only counted in grams and basically stay in a laboratory stage, and in the silica gel column chromatography process, more toxic solvents such as chloroform, benzene, ethyl acetate and the like are required to be consumed, so that the industrial mass production condition is not met.

In some embodiments, the volume ratio of the first extract to the second extractant is 1:3, 1:4, 1:5, 1:6, 1:7, 1:8, 1:9, 1: 10. In some embodiments, the volume ratio of acetone to petroleum ether in the second extractant is 1:1, 1:2, 1:3, 1: 4.
In a further embodiment, the step of mixing the first extract with the second extractant in a volume ratio of 1 (3-10) comprises:
mixing the first extract with a mixed solvent of acetone and petroleum ether in a volume ratio of 1 (2-4) according to a volume ratio of 1 (3-10), stirring and extracting for 1-3 times, each time for 1-3 hours, filtering, and taking filter residue; then, mixing the filter residue with a mixed solvent of acetone and petroleum ether in a volume ratio of 1:1 according to a volume ratio of 1 (3-10), stirring and extracting for 1-3 times, each time for 1-3 hours, filtering, and naturally volatilizing the filter residue to obtain a second extract.
Therefore, the influence of the residual impurities in the extract on the extraction of the active ingredients can be reduced, so that the enrichment amount of the flavonoid compounds in the third extractant part in the subsequent step S043 is further improved, and the extraction efficiency of the flavonoid compounds is improved.
In the step S043, the third extractant is a mixed solvent in which acetone and petroleum ether are mixed according to the volume ratio of (2-4) to 1, the polarity of the mixed solvent is similar to that of the flavonoid compound, the second extract and the third extractant are mixed according to the volume ratio of 1 (3-10), and the flavonoid compound in the silica gel adsorption powder can be enriched in the third extractant. In some embodiments, the volume ratio of the second extract to the third extractant is 1:3, 1:4, 1:5, 1:6, 1:7, 1:8, 1:9, 1: 10. In some embodiments, the volume ratio of petroleum ether to acetone in the third extractant is 1:2, 1:3, 1: 4.
Specifically, in step S05, the propolis extract is decolorized, filtered, and the filtrate is concentrated to obtain a propolis refined extract.
