Study Notes
Alkaloid-Producing Organisms
- Plants, fungi, and bacteria can produce alkaloids
Alkaloid Composition
- Besides carbon, hydrogen, and nitrogen, alkaloids can contain oxygen, sulfur, and occasionally other elements like chlorine, bromine, or iodine
Pharmacological Activities of Alkaloids
- Alkaloids can exhibit various pharmacological activities, including analgesic, antispasmodic, antimicrobial, antiviral, and anti-inflammatory effects
Additional Activities of Alkaloids
- Certain alkaloids have been found to exhibit antioxidant, anticancer, and immunomodulatory activities
- Some alkaloids can also act as enzyme inhibitors or have neuroprotective effects
Purifying Alkaloids
- One method for purifying alkaloids from crude extracts is through repetitive recrystallization, which involves dissolving the extract in a solvent, filtering, and then crystallizing the alkaloid
