Process for obtaining non-allergic propolis
WIPO Patent Application WO/2011/114291
Assignee: GM Ricchiuto, CS Gardana, SD Guglielmetti
Publication Date: Sept. 22, 2011

The present invention relates to a process for obtaining a derivative of propolis having a reduced content in allergenic substances. Also disclosed is a method of treating raw propolis or a derivative thereof and a hydroalcoholic derivative of propolis for use in the nutraceutic and cosmetic field.

Propolis produced by bees (Apis mellifera) is obtained from resinous exudates of the plants bark and leaf buds, e. g. poplar, beech, birch, chestnut, pine, etc., which are collected and processed by bees through their salivary secretions and wax addition. At RT, propolis appears as a sticky and malleable substance, having an aromatic smell and a different color depending on the source plant. Its chemical composition depends on the original plant of the resinous exudate, as well as the provenance area and the collection season. Propolis coming from plants of the Populus genus consists of resin (20-55%), wax (30-40%), volatile oils (5-10%) and various phenol compounds (10-30%), including, in particular, flavonoids. Phenolic portion also comprises phenylalkyl acids, such as cinnamic acid, caffeic acid, ferulic acid and p-coumaric acid and some esters thereof. Owing to some components thereof, propolis has numerous biological and pharmacological properties, including antibacterial, antiviral, antifungal, anti-inflammatory, antioxidant, immunostimulating, cariostatic, anti-tumour and anti-Helicobacter pylori activity.

For these properties, the use of propolis-based preparations has been known for a long time in popular medicine and the main applications relate to treatment of respiratory tract infections, flu, acne, wounds, burns, herpes, gingivitis and stomatitis, as well as prevention of caries. Propolis is also used in the cosmetics field for the formulation of creams, ointments, shampoos, lotions, gels and the like.
