Jan 31, 2014 · Reserpine is a natural product isolated from the roots of the shrub Rauwolfa serpentine. It was first synthesized in 1956 by Nobel Prize winner R.B. Woodward. It is used as a tranquilizer and sedative. When 1.00g reserpine is dissolved in 25.0g camphor, the freezing point depression is 2.63oC (Kf for camphor is 40.oC-kg/mol).
