E o hypothesis of Plinius that propolis originates from the buds of plants [70]. A series of studies performed within the USA led towards the detection of little amounts of vitamins B1, B2, B6, C, and E too as nicotinic acid and pantothenic acid in propolis [71?73]. In 1957, Ushkalova identified 4 kinds of wax in propolis, all varying in colour [74]. Ahead of 1967 a series of research were conducted on the physiological action and therapeutic makes use of of flavonoids [75]. Powers located that all flavonoids studied by him showed inhibitory activity towards one or much more of ten bacteria strains [76]. The studies on chemical Venglustat site composition of propolis have been continued in the 1960s. At first, propolis was believed to be of very complicated, but rather continuous chemistry, like beeswax [77]. Later, even so, the evaluation of quite a few samples from unique geographic regions also as application of advanced laboratory strategies showed that the chemical composition of bee glue is hugely variable. In 1969 Popravko together with others separated and identified two flavanones and isovanillin too as six flavonoid pigments in propolis [78, 79]. Soon after Lavie had demonstrated that propolis shows antibacterial activity towards Bacillus subtilis, Bacillus alvei, and Proteus vulgaris [80] French scientists managed to isolate from propolis extracts the flavon galangin, which was identified to become partly accountable for this activity [81]. Later exactly the same team isolated and identified pinocembrin, tectochrysin and isalpinin [82]. In 1970 Cizmarik and Matel reported separation and identification of three,4-dihydroxycinnamic acid and 4-hydroxy-3-methoxycinnamic acid which are present in propolis [83, 84]. Nikiforov with coworkers detected copper and manganese in propolis [85], and in the similar time Herold examined ash residue of propolis and discovered iron,9. “Dr Propolis”In the years 1967?973 a series of research have been performed in Denmark, the results of which turned to be sensational.six The effectiveness of propolis in therapy was proved as well because the fact that it produces almost no sideeffects. Dr Karl Lund Aagaard, a Danish biologist, earned the name “Dr Propolis” for his exploits of more than 20 years of propolis collecting and study. Soon after observing the effects of propolis on more than 50,000 individuals in Scandinavia, Dr Aagaard drew the following conclusions: The field of influence of Propolis is exceptionally broad. It contains cancer, infection on the urinary tract, swelling on the throat, gout, open wounds, sinus congestion, colds, influenza, bronchitis, gastritis, ailments with the ears, periodontal disease, intestinal infections, ulcers, eczema eruptions, pneumonia, arthritis, lung illness, stomach virus, headaches, Parkinson’s disease, bile infections, sclerosis, circulation deficiencies, warts, conjunctivitis and hoarseness [102]. In 1976 Aagaard patented a method for purifying and separating propolis derived from beehives. The process included the actions of quick-freezing untreated propolis repeatedly at temperatures under -20 C and then crushing the treated propolis to smaller sized particles at a temperature below ten C. Next, the said particles were separated to a variety of fractions according to PubMed ID:http://www.ncbi.nlm.nih.gov/pubmed/21095114 size, and also the fractions containing most impurities had been dissolved and filtered in a fluid filter for complete utilization of all propolis present. Aagaard found that it is actually not essential to extract the individual antibiotics from the propolis but that the substance in its all-natural kind has a effective curative.
