What is endone made from and what is morphine made from?

Endone is a brand name for a formulation of oxycodone, which is a semi-synthetic opioid derived from thebaine, a natural alkaloid found in the opium poppy. Morphine, another opioid, is directly derived from opium, specifically from the sap of the opium poppy plant. Both substances are used for pain relief but differ in their chemical structure and potency.
