The demise of vitalism
1828, preparation of urea from inorganic compounds indicates the demise of “vitalism”.
By the 18th century, some pure organic compounds were obtained.

Turtric acid was obtained from grape juice,from lemon juice, and urea was purified from urine.
In 1806, famous chemist, Berzelius J. first used the word “organic chemistry”, and states, organic compounds could not be produced without “vital force（生命力）”
