Hydrocarbon Composition of Beeswax (Apis Mellifera) Collected from Light and Dark Coloured Combs

The hydrocarbon composition of beeswax secreted by Apis mellifera was characterised. In the studies, analyses were made of virgin beeswax (obtained from light combs, socalled „wild-built combs“) that was collected at different dates, and beeswax obtained from dark combs („brood combs“). A qualitative analysis did not show any differences in the hydrocarbon composition of beeswax originating from light and dark coloured combs. The same hydrocarbons (n-alkanes, alkenes, and dienes) were identified in virgin beeswax and beeswax collected from brood combs. However, the studies showed differences in the content of n-alkanes in the beeswax obtained from light and dark coloured combs. In comparison to the virgin beeswax, the beeswax obtained from dark combs had higher content of the total n-alkanes, higher total contents of even-numbered alkanes and odd-numbered alkanes, and higher contents of certain alkanes. Furthermore, it has been found that the hydrocarbon composition of beeswax did not depend on the collection period.
