Abstract

Propolis,
a greenish resinous collected by bees, mainly from
plants around their habitat, is
a Greek word resulting from the prefix "pro" (preservation or defense) with "polis" (hive or community or
cluster). There are
13 types of propolis in Brazil, which vary according to the geographical and
botanical origin regions and its different chemical compositions².
The green propolis
(GrProp) type, derived from plant Baccharis
dracunculifolia, popularly known as rosemary-of-field, gained prominence
for its varied chemical constitution, mainly related to flavonoids. In this study was evaluated the seasonal effect on the chemical
composition of GrProp from Minas Gerais (Brazil) in a period of six years. The GrProp
was collected at February, March, May, July, September and October during six
years (2008-2013). The chemical composition of thirteen flavonoids of GrProp
was evaluated by RP-HPLC and statistical analysis of the results. The
relative amounts of the majority of GrProp flavonoids were similar in most
analyzed samples p-Coumaric acid, chrysin, galangin and kaempferol showed
statistically differences in the analyzes made during the study months and
through the period of analysis. Nevertheless, the results indicated that
GrProp maintained similar and stable characteristics through the six years of
study.
