Alkaloids with the piperidine nucleus, such as pelletierine (Punica grana-tum), lobelanine Lobelia inflata) and piperine Piper nigrum), have a typical biosynthesis pathway. It starts with L-lysine and continues via cadaverine (biogenic amine), A -piperideine and A -piperidinium cations and lobelanine, to be synthesized as lobeline. Piperine is synthesized from A -piperideine via piperidine (Figure 49). For the transformation from A -piperideine to A -piperideine cation, the residue from acetyl-CoA is needed, together with SAM activity in the transformation to lobelanine. Piperine is synthesized from piperidine through the formation of amide.

Commercially available black pepper comes from the entire unripe fruit of a Piper nigrum L. plant and is valued for its pungent taste and aroma. Besides its hot flavor, there are many folk medicine remedies using black pepper. It has antiallergic activity. Piperine strongly inhibits hepatic arylhydrocarbonhydroxylase and UDP-glucuronyl transferase activities. Some proven uses for black pepper extracts are as an insecticide and as a tumor inhibitor. To research claims such as these, it is necessary to isolate the components of pepper. 

Herbal effects on absorption can affect the bioavailability of antibiotics and has been demonstrated for Khat (Catha endulis) users (Attef et al., 1997). Absorption and decreased metabolism of the asthma drug theophylline are also affected by piperine from black pepper (Piper nigrum, Piper longum).

An acyl transferase which catalyzed the synthesis of piperine in the presence of piperine and piperoyl-coenzyme A was isolated from shoots of Piper nigrum and characterized [396], The prior synthesis of piperoyl-coenzyme A assisted in this study [397]. 

Ethnopharmacological research on natural products can contribute to the discovery of new active compounds with novel structures which may serve as leads to the development of new antiepileptic drugs. An example is the isolation of the active alkaloid piperine from Piper nigrum L. which is one of the component herbs of an ancient Chinese medicine used for the treatment of epilepsy. Its structural modifications resulted in the synthesis of seven derivatives including antiepilepserine which was found to be more potent than the parent compound with fewer side effects and it has been used as an antiepileptic drug [10-12].

While for developing of simple piperidine alkaloids, e.g., pelletierine (Punica granatum), piperine (Piper nigrum et longum), and lobeline (Lobelia inflata), only one molecule of lysine is necessary, for quinolizidine alkaloids - e.g., lupinine (Lupinus luteus), sparteine of antiarrhythmic activity (Sarothamnus scoparius), and cytisine of respiratory stimulant effect (Laburnum species) - two molecules of lysines are indispensable. It was also proved that lycopodine (Lycopodium tristachyum, clubmoss) of quinolizidine structure has no polyketide origin, but it is a modified dimer of pelletierine, which, in turn, is derivable from lysine and acetate.

Kanaki et al. [12] worked out a rapid, economical method for isolation of piperine from Piper nigrum L. The method involves extraction of the fruit powder with glacial acetic acid from which piperine was partitioned into chloroform and subsequently crystallized.

Microwave is used to irradiate the plant material during the extraction process. Microwave irradiation is reported to cause rupture of cells, thereby facilitating the action of solvents on the cells [35]. The usage of microwave irradiation was employed for the isolation of curcumin from turmeric [36-39], piperine from Piper nigrum [40], solanesol from tobacco leaves [41], and artemisin from Artemisia annua [42].

Black, white, green and red peppers are fruits of the same plant Piper nigrum, Piperaceae) native to south India that contains protoalkaloid pipeline as the major hot component this is (2E,4 )-l-piperoylpiperidine, an amide of piperic acid, systematic name (2 ,4 )-5-(l,3-benzodioxol-5-yl)-N-piperidinylpenta-2,4-dienamide. Black pepper is obtained from immature, but already fuUy developed fruits that are fermented during drying. Green peppers are quickly sun-dried unripe berries. White pepper is produced from fully ripe berries by removing the red skin. The content of piperine in black and white pepper is 3-8% (see Section 10.3.2.1.2).
