A study of the preparation of propolis extracts and its applications

, : A study of the preparation of propolis extracts and its applications. Ciencia e Tecnologia de Alimentos 18(3): 313-318

Ethanolic extracts of propolis were studied using UV spectrophotometry and reversed phase-HPLC. Maximum absorption of propolis extracts was at 290 nm, resembling flavonoid compounds. The most common flavonoids were: isosakuranetin, quercetin, and kaempferol in 60% ethanol extracts; pinocembrin and sakuranetin in 70% ethanol extracts and kaempferide, acacetin, and isorhamnetin in 80% ethanol extracts.
