Elemental analysis of scorpion venoms

Area of Science:

• Toxicology
• Biochemistry
• Analytical Chemistry

Background:

• Scorpion venom contains diverse biomolecules impacting host physiology.
• Venoms are complex mixtures with potential therapeutic applications.
• Understanding venom composition is crucial for pharmacological research.

Purpose of the Study:

• To catalog the elemental composition of venoms from medically significant Arabian scorpions.
• To quantify specific elements and assess their abundance in different scorpion species.

Main Methods:

• Elemental analysis of crude venom using Inductively Coupled Plasma Mass Spectrometry (ICP-MS).
• Quantification of nine specific elements using appropriate standards.
• Total quant analysis for global elemental composition.

Main Results:

• Fifteen elements, including sodium, potassium, and calcium, were abundant (PPM).
• Thirty-six elements were detected at parts per billion (PPB) levels.
• Copper was highest in Androctonus species, while zinc and manganese were higher in Leiurus species.

Conclusions:

• Elemental composition varies significantly between scorpion species.
• These findings enhance understanding of venom mechanisms and pharmacological potential.
• Data provides a foundation for future research into venom-derived therapeutics.
