Alkaloids are devided based on their shape and origin.
1.True alkaloids
2.protoalkaloids
3.pseudoalkaloids
True alkaloids derive from amino acid and they share a heterocyclic ring with nitrogen. true alkaloids have bitter taste and appear as white solid, with the exception of nicotine which appear as brown liquid. True alkaloids form water soluble salts.

What is alkaloid?
Alkaloids are a broad group of naturally occurring compounds found in plants, animals, and fungi. They often have pronounced physiological effects on humans and other animals, and many alkaloids are used in medicine or recreation due to their psychoactive properties. Examples of alkaloids include caffeine, nicotine, and morphine.

What is the mechanism of the reaction between Wagner's reagent and an alkaloids?
Wagner's reagent, which is an aqueous solution of iodine and potassium iodide, reacts with alkaloids containing nitrogen atoms to form a brown complex. This reaction is based on the oxidation of the nitrogen atoms in the alkaloids by iodine, resulting in the formation of the colored complex. The intensity of the brown color can be used to detect the presence of alkaloids in a given sample.
Why does Dragendorff's reagent form a yellow precipiate with alkaloids?
Dragendorff's reagent contains bismuth and potassium iodide. When it reacts with alkaloids, such as morphine or nicotine, a yellow precipitate is formed due to the formation of insoluble bismuth iodide complexes with the alkaloids. This reaction is commonly used to test for the presence of alkaloids in a sample.
True or false mendeleev also grouped elements that has similar properties?
True. Mendeleev organized the elements into the periodic table based on their atomic weight and similar chemical properties. He noticed that elements with similar properties tended to occur at regular intervals, leading to the periodicity of the elements.

What are alkaloids glycoside flavonoids?
Alkaloids, glycosides, and flavonoids are classes of naturally occurring compounds found in plants. Alkaloids are nitrogen-containing compounds often associated with pharmacological effects, such as caffeine and morphine. Glycosides are compounds formed from a sugar and a non-sugar moiety, which can have various biological activities, including medicinal properties. Flavonoids are a group of polyphenolic compounds known for their antioxidant properties and are commonly found in fruits, vegetables, and beverages like tea and wine.

What are the naturalcomponents of opium?
Opium is derived from the latex of the opium poppy (Papaver somniferum) and contains several natural components, primarily alkaloids. The main alkaloids found in opium include morphine, codeine, and thebaine, each having distinct pharmacological effects. Other minor alkaloids present include papaverine and noscapine. These compounds are responsible for opium's analgesic and sedative properties.
What is chemical composition of cinchona bark?
it contains 25 quinoline alkaloids .important alkaloids are quinine, quinidine, cinchonine & cinchonidine. Other alkaloids are quinicine ,cinchonicine, hydroquinine & hydrocinchonidine. Also contains Quinovin , a bitter glycoside responsible for bitter taste,yields on hydrolysis of quinovic acid and quinovosc,a sugar derivative.cinchona bark also contains tannins as quinic acid and cincho tannic acid.
Physiological functions of the alkaloids in the organism?
1. Most of the alkaloids are poisonous. As a poisonous agent they protect plants from insects & herbivores. 2. They may act as a reservoir for protein synthesis. 3. They occur as pigments , attract animal & insects for pollination .
