WebbThe first step in identifying opium's active ingredient, morphine, was its chemical isolation in the early 1800s by Wilhelm Sertürner. The subsequent elucidation of morphine's chemical formula and Sir Robert Robinson's derivation of morphine's structural formula, which won him the 1947 Nobel Prize in Chemistry, round out 150 years of the ...
