Abstract

Propolis is well known for its potential
applications but also for its chemical complexity, making it very hard to
define quality standards for its commercialization. Every day it is possible
to find new publications on this bee product describing a new singularity, a
particular substance with high bioactivity never described or a new
application. This systematic increment in scientific information, although
relevant, do not always enable a clear comparison between samples due to the
different methods and procedures used to assess its quality parameters. To
strength the scientific studies on propolis and establish a background for
future definition of standards for industry, producers and laboratories, the
Propolis Working group of the International Honey Commission, performed an
inter-laboratory study to harmonize basic analytical methods and evaluate
their accuracy and robustness.

The collaborative study was
accomplished by 12 laboratories from 9 countries and a company experienced in
propolis trade. The samples under analysis, representing fifteen different
origins around the globe, where fractionated and distributed to each
laboratory, and so all participants analysed the same material. Overall, six
parameters were evaluated: ashes, wax and balsamic extract on raw propolis,
and total-phenolics, flavones and flavanones on propolis extract. The results
were analysed following the international guidelines ISO 5725¹.
Outliers were removed using Cochran’s test, to check the homogeneity of
variances at certain levels, and Grubb test’s, to check the consistency of
the laboratories average. The results revealed good reproducibility for ash,
wax, balsamic content and flavones, while for flavanones the method is
clearly unsuitable.
