WebNot since the late 1970s has a single work presented the biology of this heterogenous group of secondary alkaloids in such depth. Alkaloids, a unique treatise featuring leaders in the field, presents both the historical use of alkaloids and the latest discoveries in the biochemistry of alkaloid production in plants alkaloid ecology, including marine … WebAlkaloids are the most diversified nitrogen-containing secondary metabolites having antioxi-dant, and antimicrobial properties and are extensively used in pharmaceuticals to treat different types of cancer. Nicotiana serves as a reservoir of anticancer alkaloids and is also used as a model plant for the de novo synthesis of various anti-cancer molecules …
Alkaloid - an overview ScienceDirect Topics
WebPlants have basically two types of metabolites namely Primary metabolites and Secondary metabolites. Primary metabolites are mainly used for the photosynthesis, growth, development, and respiration of plants. Secondary metabolites accumulate in plants and respond as a defense mechanism of the plants. WebWell-known alkaloids include morphine, strychnine, quinine, ephedrine, and nicotine.

Ecological Role of Alkaloids
WebImportant alkaloids include morphine, strychnine, atropine, colchicine, ephedrine, quinine, and nicotine. They are most common in herbaceous plants, but some occur in … Alkaloids are generated by various living organisms, especially by higher plants – about 10 to 25% of those contain alkaloids. Therefore, in the past the term "alkaloid" was associated with plants. The alkaloids content in plants is usually within a few percent and is inhomogeneous over the plant tissues. … Meer weergeven Alkaloids are a class of basic, naturally occurring organic compounds that contain at least one nitrogen atom. This group also includes some related compounds with neutral and even weakly acidic properties. Some … Meer weergeven Alkaloid-containing plants have been used by humans since ancient times for therapeutic and recreational purposes. For example, … Meer weergeven Most alkaloids contain oxygen in their molecular structure; those compounds are usually colorless crystals at ambient conditions. … Meer weergeven Biological precursors of most alkaloids are amino acids, such as ornithine, lysine, phenylalanine, tyrosine, tryptophan, histidine, aspartic acid, and anthranilic acid. Nicotinic acid can be synthesized from tryptophan or aspartic acid. Ways of alkaloid … Meer weergeven The name "alkaloids" (German: Alkaloide) was introduced in 1819 by the German chemist Carl Friedrich Wilhelm Meißner, and is derived from late Latin root alkali and the … Meer weergeven Compared with most other classes of natural compounds, alkaloids are characterized by a great structural diversity. There is no uniform classification. Initially, when knowledge of chemical structures was lacking, botanical classification … Meer weergeven Because of the structural diversity of alkaloids, there is no single method of their extraction from natural raw materials. Most methods exploit the property of most alkaloids to … Meer weergeven WebAt least 12 plants have been proven by many studies and house owners as effective in repelling rats.
