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.

Oleoresin Black Pepper Obtained by the solvent extraction of the dried fruit of Piper nigrum L. (Fam. Piperaceae) as a dark green, olive green, or olive drab extract usually consisting of an upper oily layer and a lower crystalline layer. It may appear as a homogeneous emulsion if examined shortly after the oleoresin has been homogenized, but the product separates on standing. It may be decolorized by partial removal of chlorophyll.

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].

Unsaturated Amides. In 1971, a group of pungent compounds (isobutylamides) obtained from members of the families Compositae and Rutaceae were described by Jacobsen (Jacobsen, 1971) to have limited use as insecticides. The compounds were characterized as unstable with a marked tendency to polymerize. Examination of extracts of the fruit of the black pepper Piper nigrum, using the aduzki bean weevil as a bioassay, resulted in the isolation of three isobutylamides (13-15) which displayed insecticidal activity (when combined equimolarly) to the pyrethrins (Miyakado et al., 1983, 1989). Based upon the observations of Miyakado and earlier reported test results for synthetic analogs of the compounds described by Jacobsen, Elliot and co-workers defined a basic amide structure to...
