The preparation of a special chapter in this series on the constituents of pepper (6) led us to ignore pepper alkaloids. After publication of the chapter, we discovered that it dealt with the alkaloids of red pepper species (Capsicum, So-lanaceae), which are not pyrrolidines, and the purpose of this addendum is to provide a survey of the pyrrolidine alkaloids contained in black pepper species Piper, Piperaceae. 

Prenylated salicylic acid derivatives, including 3-famesyl-2-hydroxy-benzoic acid (Fig. 7) isolated from the leaves of Piper multiplinervium C. DC. (Piperaceae) showed mii-Helicobacter pylori activity at MIC 37.5 pg/mL Boropinic acid (Fig. 7), an active constituent isolated from Boronia pinnata (Fam. Rutaceae) had activity against HP with an MIC value of 1.62 pglmL Five novel compounds, psoracorylifols A-E (1-5) with important activity against Helicobacter pylori MICs 12.5-25 pg/mL were isolated from a well-known traditional Chinese medicine (TCM), the seeds of Psoralea corylifolia by Yin et al 2006.

The members of the plant family Piperaceae are well known in traditional pharmacology in Asia and Africa as medicines and insecticides. Piper nigrum L. (Piperaceae, black pepper) has traditionally been used as a...

The species with the higher allelopathic potentials were Piper auritum. Piper hispidum, Croton pyramidalis, and Siparuna nicaraguen-sis. The essential oils of the Piperaceae were highly inhibitory while that of Croton pyramidalis was less inhibitory and even produced stimulations (Table III).

Pepper oil and pepper oleoresin are obtained from the black pepper Piper nigrum L. (Piperaceae). Pepper oil is produced by steam distillation of whole or crushed fruits. The oil is an almost colorless to bluish-green liquid with a characteristic odor, reminiscent of pepper, but without the pungency of the spice. 

Several phenylpropanoid compounds have pronounced anti feeding activity. Isoasarone (from Piper futokadzura, Piperaceae) and piperenone were highly active against Spodoptera litura (54). 

A series of structurally similar compounds derived by acetate extension of phenylpropanoid precursors is also found in the Piperaceae. Pipercide from Piper nigrum (Piperaceae) was insecticidal, but the mixture of amides from this plant was significantly more toxic and it appears that co-occurring compounds exert synergistic effects (120). 

Among many others, well-known families rich in essential oil bearing species are Apiaceae, Asteraceae, Cupressaceae, Hypericaceae, Lamiaceae, Lauraceae, Myrtaceae, Pinaceae, Piperaceae, Rutaceae, Santalaceae, Zingiberaceae and Zy-gophyllaceae [1-4, 8-11, 39].
