Huaxing propolis, as a beneficial supplement to dietary flavonoid deficiency, participates in human metabolism, but it cannot be stored in the body for a long time. Health is a continuous life process. Some people eat propolis as a tonic in autumn and winter, but don't eat it in spring and summer for fear of getting angry. In fact, in spring and summer, the temperature is high, the activity is large, and the metabolism is vigorous, so it is necessary to supplement the insufficient flavonoids in the diet in time. In addition, propolis is non-toxic and can be safely eaten.

Propolis is a gelatinous substance which is collected by bees from tree buds, bark and other parts of plants, and then mixed with the secretions of bee tongue glands, wax glands and other glands, and transformed by bees. Bees apply these substances to the surface of the whole hive; On the one hand, it plays the role of anti-corrosion and anti-oxidation, on the other hand, it bonds the hive and blocks the gap, so that many germs cannot reproduce in the hive.

Propolis is an extremely rare natural resource, known as "Zijin". What's even more peculiar is that while propolis suits the right medicine, other ingredients will not harm the human body, but can play a comprehensive role in regulating and balancing the immune function of the body, which is why many consumers often have unexpected surprises when taking propolis.

Chemical constituents of propolis

Today, with the high development of science and technology, people not only walk on the moon, but also understand the mystery of the nucleus. So people are not satisfied with the explanation that propolis is composed of resin and bee secretions. Therefore, we think it is necessary to explain the composition of propolis from the micro level.

Propolis is a natural resin substance, which is collected by bees from branches, buds and secretions of plants. The chemical substances found in propolis are: beeswax, resin, balsam, aromatic oil, fat-soluble oil, pollen and other organic substances. The research shows that there are three sources of resin substances in propolis: plant secretions collected by bees, metabolic secretions in bees and substances involved in the formation of propolis.

The newly collected propolis contains about 55% resin and sesame oil, 30% beeswax, 10% aromatic volatile oil, 5% pollen and other impurities. According to the analysis of modern science (1970s), many chemical components were separated from propolis, which proved that propolis components were extremely complex. Among them are flavonoids, acids, alcohols, phenols, aldehydes, esters, ethers, olefins, terpenoids and various amino acids, fatty acids, enzymes, vitamins and trace elements. Say it one by one.

(-) flavonoids

Flavonoids are the main and important components in propolis, which are widely distributed in the plant kingdom and are natural plant pigments. More than 20 kinds of flavonoids have been isolated from propolis, including flavonoids, flavonols and difluoroflavones.

Flavonoids are widely distributed in the plant kingdom. This natural compound plays an important role, contains many important active compounds, and has a good therapeutic effect on many diseases, so it has high medicinal value. Studies have proved that the effective components of many anti-aging, anti-inflammatory, nourishing, immune regulation and other traditional Chinese medicines are mainly flavonoids. For example, the main effective components of traditional Chinese medicines and herbs for the treatment of chronic bronchitis recorded in the Herbal Prescription of Traditional Chinese Medicine in 1970s are flavonoids. According to research, the types and quantities of flavonoids contained in propolis are far superior to any traditional Chinese medicine.

Flavonoids in propolis mainly include:

1. Flavonoids. It affects the growth of plants, plays the role of carbonic acid assimilation, and has the functions of stopping bleeding and stabilizing blood circulation.

2. Flavonoids and alcohols. It contains a lot of flavonoids and vitamins, and has the function of treating scurvy and pain. For example, riboflavin is a yellow pigment, which is composed of bark ketone and lower bond. It is a yellow transparent crystal with disinfection and nutrition functions.

3. difluoro flavonoids. This is also a flavonoid. In a word, flavonoids are very important components in propolis, which have a very good effect on stabilizing blood circulation, increasing vitality, improving immune level, diminishing inflammation and detoxifying, and regulating metabolism and physiological functions.

(2) Phenolic acids

The acidic compounds contained in propolis include benzoic acid, p-hydroxybenzoic acid, caffeic acid, ferulic acid, isoferulic acid, cinnamic acid, phenylacrylic acid and so on.

(III) Flavanol

Alcohol compounds include hydroxyl 7 methyl flavanol, 5,7 dihydroxy flavanol, benzyl 3,5 dimethoxybenzyl alcohol, cinnamyl alcohol, 2-SH methoxybenzyl alcohol, coniferyl alcohol, guaiacol, etc.

(4) Aromatic volatile oil and alkene terpenoids

The aromatic volatile oil in propolis accounts for 4- 10%, and there are many kinds, and sometimes aromatic substances volatilize. The volatile oil content of aged propolis decreased, and the smell became weak. These components have certain bactericidal and bacteriostatic effects.

(5) Phenols, aldehydes, ketones, esters and ethers.

Propolis contains eugenol, vanillin, isovanillin, benzaldehyde, cyclocitral, 4,5-dimethyl -4- benzo -2- cyclohexenone, p-coumaric ester, caffeic acid ester, cyclic alcohol benzoate, ethyl cyclic alcohol formate, coniferyl alcohol benzoate, p-coumaric alcohol benzoate, ferulic acid benzoate, styrene ether, p-methoxystyrene acid, etc.

(6) polysaccharide

Polysaccharides in propolis account for 2 ~ 3% of the total.

(7) protein

Protein component isolated from propolis include enzyme and amino acid.
