Abstract
A new and useful method for extracting propolis from substantially clean raw material to obtain a dry propolis powder. Depending upon the method employed, either a water soluble propolis powder or an organic soluble propolis powder may be obtained. A unique method for purifying the propolis extract is also disclosed. Both the methods for extracting propolis-containing raw material and the water soluble dry propolis powder are claimed. The propolis powder exhibits, among other things, bactericidal viricidal, analgesic, anaesthetic and regenerative properties.
Claims20
A method for extracting propolis, said method comprising the steps of:
- a. selecting a quantity of raw material from the group consisting of raw propolis and unprocessed beeswax;
- b. placing said quantity of raw material in a container and covering said quantity with solvent wherein about 1-1.5 liters of said solvent are added per 500 g of said quantity, and wherein said solvent is selected from the group consisting of ethyl alcohol, isopropyl alcohol, n-butyl alcohol, sec-butyl alcohol, tert-butyl alcohol, ethyl ether, benzyl alcohol, propylene glycol, dimethyl sulfoxide, ethylene glycol, n-propyl alcohol, methyl alcohol, benzyl benzoate, acetone, polyethylene glycol, glacial acetic acid, aqueous solutions of said solvents, and mixtures thereof;
- c. maintaining the mixture of step b. at a temperature of about 0.degree.-37.degree. C. for about 1-10 days with periodic agitation to obtain a propolis-containing solution;
- d. filtering said solution to obtain a propolis-containing filtrate;
- and
- e. removing said solvent from said filtrate to obtain a dry propolis powder.
A method for extracting and purifying propolis, said method comprising the steps of:
- a. selecting a quantity of raw material consisting essentially of raw propolis;
- b. placing said quantity of raw material in a container and covering said quantity with solvent wherein about 1-1.5 liters of said solvent are added per 500 g of said quantity, and wherein said solvent is selected from the group consisting of ethyl alcohol, isopropyl alcohol, n-butyl alcohol, sec-butyl alcohol, tert-butyl alcohol, ethyl ether, benzyl alcohol, propylene glycol, dimethyl sulfoxide, ethylene glycol, n-propyl alcohol, methyl alcohol, benzyl benzoate, acetone, polyethylene glycol, glacial acetic acid, aqueous solutions of said solvents, and mixtures thereof;
- c. maintaining the mixture of step b. at a temperature of about 0.degree.-37.degree. C. for about 1-10 days with periodic agitation to obtain a propolis-containing solution;
- d. filtering said solution to obtain a propolis-containing filtrate;
- e. cooling said propolis-containing filtrate to a temperature of at most about -20.degree. C.;
- f. maintaining said cooled filtrate at said temperature for about 24 hours;
- g. agitating said cooled filtrate;
- h. filtering said cooled filtrate while maintaining said temperature to obtain a purified propolis-containing filtrate;
- and
- i. removing said solvent from said purified filtrate to obtain a purified dry propolis powder.
A method for obtaining a water soluble propolis powder, said method comprising the steps of:
- a. selecting a quantity of raw material consisting essentially of raw propolis;
- b. placing said quantity of raw propolis in a container and covering said quantity with solvent wherein about 1 liter of said solvent is added per 500 g of said quantity, and wherein said solvent is selected from the group consisting of 10-25% aqueous solutions of ethyl alcohol, isopropyl alcohol, sec-butyl alcohol, tert-butyl alcohol, ethyl ether, propylene glycol, dimethyl sulfoxide, ethylene glycol, n-propyl alcohol, methyl alcohol, acetone, polyethylene glycol, glacial acetic acid, and mixtures thereof;
- c. maintaining the mixture of step b. at a temperature of about 0.degree.-37.degree. C. for about 1-10 days with periodic agitation to obtain a propolis-containing solution;
- d. filtering said solution to obtain a propolis-containing filtrate;
- and
- e. removing said solvent from said filtrate to obtain a water soluble dry propolis powder.
