Piperine, possibly along with its isomer chavicine, [2] is the compound [3] ... ("B" denotes one mole of the alkaloid base in this and the following formula).
The most important representative of piperidine alkaloids is piperine, which is responsible for the pungent taste of pepper. The piperidine alkaloids also include the sedum alkaloids (e.g. sedamine), pelletierine, the lobelia alkaloids (e.g. lobeline), the conium alkaloids (such as coniine) and the pinus alkaloids.
Piperidine is used as a solvent and as a base. The same is true for certain derivatives: N-formylpiperidine is a polar aprotic solvent with better hydrocarbon solubility than other amide solvents, and 2,2,6,6-tetramethylpiperidine is a highly sterically hindered base, useful because of its low nucleophilicity and high solubility in organic ...
Piperic acid is a chemical often obtained by the base-hydrolysis of the alkaloid piperine [1] from black pepper, [2] followed by acidification of the corresponding salt.Piperic acid is an intermediate in the synthesis of other compounds such as piperonal, and as-such may be used to produce fragrances, perfumes flavorants and drugs as well as other useful compounds.

Base extraction is achieved by processing the raw material with alkaline solutions and extracting the alkaloid bases with organic solvents, such as 1,2-dichloroethane, chloroform, diethyl ether or benzene. Then, the impurities are dissolved by weak acids; this converts alkaloid bases into salts that are washed away with water.
By extension, certain neutral compounds biogenetically related to basic alkaloids are included. While piperine may not be considered a basic nitrogen compound because it is an amide, piperine is referred to as an alkaloid widely in the literature along with numerous other amide compounds (e.g. colchicine, capsaicin).
Piperine remains the most potent and extensively researched bioenhancer till date. It is safe, effective, extremely economical and easily manufactured for commercial use. It is also a broad spectrum bioenhancer acting on several classes of modern drugs as noted elsewhere.
