Abstract:

The flavone glycosides of propolis were hydrolyzed by hydrochloric acid, and then the antioxidation of its hydrolystes was determined. The results indicated that the flavone glycosides of propolis can be hydrolyzed into flavone glycones effectively by hydrochloric acid. The hydrolysis conversion rate of rutin reaches 59.1%, and the contents of kaempferol and isorhamnetin are increased by 1 to 3 times. Moreover, the scavenging capacity to DPPH radicals and the antioxidant activity for lard oil of the hydrolysates are improved obviously.

Key words: propolis, flavone glycoside, acid hydrolysis, antioxidation
