Analysis of alkaloids (indole alkaloids, isoquinoline alkaloids, tropane alkaloids)

open access: yes, 2020
Alkaloids are a large cluster of molecules found in Mother Nature all over the world. They are all secondary compounds and collection of miscellaneous elements and biomolecules, derived from amino acids or from transamination. This diverse chemical group is categorized, based on the amino acids that deliver their nitrogen atom and part of their ...
