What alkaloids are in the roots of the papaver somniferum poppy?

The roots of the Papaver somniferum poppy primarily contain alkaloids such as morphine, codeine, and thebaine. Morphine is the most abundant and is well-known for its analgesic properties. Codeine, a less potent derivative, is often used in pain relief and cough suppression, while thebaine serves as a precursor for synthesizing other opioids. These alkaloids contribute to the plant's use in both medicinal and recreational contexts.
