Isolation Techniques
Plant or animal tissues always have several classes of compounds or active components with markedly different structures. Each class usually contains several or a lot of compounds closely related in the structure. Natural product chemistry usually begins from the separation and isolation of single pure compound from such many similarly related ingredients.
Historically, isolation of secondary metabolites from the target plant begins by extraction with solvents. For example, alkaloids are extracted by acidic water, and after basification of the extract, they are again extracted with organic solvent such as chloroform.
