Abstract
Toxicity studies
■ Venom manually and electrically extracted before storage
The LD50 values of the venoms for the two honeybee
subspecies using two extracted methods revealed that, the
Egyptian bee venom has significally higher toxicity than
Carniolan bee venom. The venom electrically stimulated has
significant higher toxicity than the manually extracted. The
present results of spectrophotometer and electrophoresis studies
were supporting to these results of the toxicity studies.
■ Venoms electrically extracted after storage for 12 and 24
months
The toxicity was significantly decreased in the different
storage conditions for venoms of the two subspecies.
In general, the lowest values of the reduction (%) in the
toxicity were under the freezer storage condition while the highest
values of the reduction (%) were under storage at room
temperature in the light for the two bee venoms during the storage
periods.
The Egyptian bee venom has significantly higher toxicity
under all storage conditions during storage periods. The reduction
(%) in the toxicity of the Carniolan bee venom was higher than
that in the Egyptian bee venom all storage condition overall the
storage periods except under freezer condition was slightly higher in the Egyptian bee venom. These results were also supported by
the present results of spectrophotometer measurements of venom
samples stored under freezer conditions after 12 and 24 months.
Finally, based on the present results of spectrophotometer,
electrophoresis and toxicity studies and comparative analysis
between Egyptian and Carniolan bee venoms and different storage
conditions, this study recommends:
• Freezing was the best storage conditions for honeybee venom
within the range that assures preserve maximum activity of
their components, stability and prolonged storage with high
quality and efficiency.
• It also recommends that the bees concerned to expand the
breeding of the Egyptian honeybee subspecies, maintain it and
encourage the beekeeping to commercial production of the
Egyptian bee venom due to it has high biological activity and
toxicity than that of the Carniolan subspecies and is the better
form for potential pharmacological source.
