propolisSampleList: Brazilian Propolis from different Harvest Seasons and different Agroecological Regions (sample list)
Description
Propolis or bee glue is a sticky dark-colored substance produced
from the collected buds or exudates of plants (resin) by bees
(Apis mellifera L.). The resin is masticated, salivary enzymes are
added, and the partially digested material is mixed with beewax
and used in the hive to seal the walls, strengthen the borders of
combs, and embalm dead invaders (Wollenweber et al., 1990).
The propolis samples are from NMR data and were collected in the
autumn (AU), winter (WI), spring (SP), and summer (SM) of 2010
from Apis mellifera hives located in southern Brazil (Santa
Catarina State). A total of 59 samples were collected, and the
distribution of samples by seasons being: SM - 16 samples, AU
and SP - 15 samples, WI - 13 samples. Also, three agroecological
regions were defined for the different apiaries, and one
distributed as follows: Highlands - 12 samples, Plain - 11 samples,
Plateau - 36 samples.
