Where Are Alkaloids Located?

The alkaloids content in plants is usually within a few percent and is inhomogeneous over the plant tissues. Depending on the type of plants, the maximum concentration is observed in the leaves (for example, black henbane), fruits or seeds (Strychnine tree), root (Rauvolfia serpentina) or bark (cinchona).

Where can you find alkaloids?

Alkaloids are found primarily in plants and are especially common in certain families of flowering plants. In fact, as many as one-quarter of higher plants are estimated to contain alkaloids, of which several thousand different types have been identified.

Where are alkaloids derived from?

Definition and Classification of Alkaloids

Most alkaloids are biosynthetically derived from amino acids such as phenylalanine, tyrosine, tryptophan, ornithine, and lysine. Alkaloids represent a wide variety of chemical structures. About 20000 alkaloids are known, most being isolated from plants.
