The first individual alkaloid, morphine, was isolated in 1804 from the opium poppy (Papaver somniferum). [1]Alkaloids are a broad class of naturally occurring organic compounds that contain at least one nitrogen atom. Some synthetic compounds of similar structure may also be termed alkaloids. [2]Alkaloids are produced by a large variety of organisms including bacteria, fungi, …

Jan 4, 2025 · The chemical structures of alkaloids are extremely variable. Generally, an alkaloid contains at least one nitrogen atom in an amine-type structure—i.e., one derived from ammonia by replacing hydrogen atoms with hydrogen-carbon groups called hydrocarbons.This or another nitrogen atom can be active as a base in acid-base reactions.The name alkaloid (“alkali-like”) …

alkaloid, Basic (see base) organic compounds of plant origin, containing combined nitrogen.Alkaloids are amines, so their names usually end in “ine” (e.g., caffeine, nicotine, morphine, quinine).Most have complex chemical structures of multiple ring systems. They have diverse, important physiological effects on humans and other animals, but their functions in the …

The biological properties of various alkaloids have also led to their use as pharmaceuticals, narcotics, stimulants and poisons (Table 2.2).Since the morphine (a well-known alkaloid from Papaver somniferum poppy) discovery, alkaloids are widely used as drugs in modern medicine such as morphine, quinine and codeine. Thus, alkaloids at lower doses are pharmacologically …

Alkaloids are the class of phytochemicals that contains nitrogen atoms in their structure and play vital physiological roles in humans and animals [25,26].Alkaloids are diverse, with about 3000 distinct alkaloids identified in plants, fungi, and animals [27].Typically, alkaloids are crystalline, colorless, non-toxic, stable, and have low molecular weight, making them ideal pharmaceutical ...
