Chemical analysis and antimicrobial activity of Greek propolis.

摘要: One new 2,3-dihydroflavone derivative, 7- O-prenylstrobopinin, and 25 known diterpenes phenolic compounds were identified from the n-butanol extract of Greek propolis. This is first time that have been isolated propolis European origin, while six are reported as constituents for time. The structures determined by spectroscopic methods, mainly concerted application 1D, 2D NMR techniques (HMQC, HMBC, NOESY) mass spectrometry. studied sample tested their antimicrobial activity against Gram (+/-) bacteria fungi five them exhibited strong activities.
