Alkaloidët janë produkte natyrore të përbërjes së caktuar, të cilët përveç karbonit, hidrogjenit dhe oksigjenit, gjithmonë përmbajnë edhe azot (zakonisht në ndonjë unazë heterociklike), i cili është bartës i vetive bazike të këtyre molekulave.

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 …

Feb 27, 2025 · alkaloid, any of a class of naturally occurring organic nitrogen -containing bases. Alkaloids have diverse and important physiological effects on humans and other animals. Well-known alkaloids include morphine, strychnine, quinine, ephedrine, and nicotine.

Alkaloids are made by a large variety of organisms, such as bacteria, fungi, plants, and animals and are part of the group of natural products (also called secondary metabolites). Many alkaloids can be purified from basic substances by acid-base extraction. Many alkaloids are toxic to other organisms. Some alkaloids have a bitter taste.

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.

Alkaloids are defined as a group of naturally occurring chemical compounds that mostly contain basic nitrogen atoms [1]. Alkaloid molecules are extremely important for biomedical science.

Jan 1, 2022 · Alkaloids are cyclic compounds containing nitrogen in a negative oxidation state which is of limited distribution in a living organism. The term “alkaloid” marks its origin from the word “alkaline” which in Arabic means “ashes of plants.”

The meaning of ALKALOID is any of numerous usually colorless, complex, and bitter organic bases (such as morphine or caffeine) containing nitrogen and usually oxygen that occur especially in seed plants and are typically physiologically active.

Apr 15, 2021 · This review's fundamental objective is to summarize the pharmacological potential of indole alkaloids that have been derived from plants and provide a detailed evaluation of their established pharmacological activities, which may contribute to identifying new lead compounds.

An alkaloid is a naturally occurring nitrogenous organic molecule that has a pharmacological effect on humans and other animals. The name derives from the word alkaline; originally, the term was used to describe any nitrogen-containing base (an amine in modern terms).
