Chemical composition of Baccharis dracunculifolia, the botanical source of propolis from the states of Sao Paulo and Minas Gerais, Brazil.

摘要

Propolis is a resinous hive product collected by honey bees from plant sources. The composition of the propolis depends upon the season, vegetation, and the area of collection. Phytochemical analyses of propolis produced from Baccharis dracunculifolia (alecrim-do-campo) in Sao Paulo and Minas Gerais, Brazil, by Africanized Apis mellifera were conducted by RP-HPTLC, RP-HPLC and GC-MS, and the absorption spectra was measured by UV-visible spectrophotometry. A distinctive characteristic of propolis and B. dracunculifolia was that both had a high proportion of the phenolic compounds artepillin C and other dihydrocinnamic acid derivatives. Based on phytochemical evidence, B. dracunculifolia was the main source of propolis produced in Sao Paulo and Minas Gerais..
