  1. Reserpine occurs in the roots of Rauwolfiaserpentina and other Rauwolfia species, suchas R. micrantha, R. canescens, and R. vomitoria Hook. It is used therapeutically as anantihypertensive agent and a tranquilizer. Itsuse has been reduced significantly because oftoxic side effects.
  2. An indole alkaloid found in Rauwolfia serpentina. Inhibits vesicular uptake of catecholamines and serotonin. Reserpine is reasonably anticipated to be a human carcinogen. Antihypertensive.
  3. An inhibitor of transport of biogenic amines into adrenal chromaffin granules
