Natural Products and the Chemistry of Life
Purpose

To demonstrate the importance of natural products in the development of new drugs


Materials

  • Aspirin (acetylsalicylic acid)
  • Willow bark
  • Water
  • Graduated cylinder
  • beaker
  • Ice bath
  • Filter paper
  • Funnel
  • Vacuum filtration apparatus

Procedure

  1. Grind the willow bark into a coarse powder
  2. Add the willow bark powder to a beaker of water
  3. Heat the mixture to boiling and then simmer for 30 minutes
  4. Cool the mixture and then filter it
  5. Add aspirin to the filtrate and stir until it dissolves
  6. Cool the mixture in an ice bath
  7. Aspirin will crystallize out of the solution
