Black pepper (Piper nigrum) is a flowering vine in the family Piperaceae, cultivated for its fruit (the peppercorn), which is usually dried and used as a spice and seasoning. The fruit is a drupe (stonefruit) which is about 5 mm (0.20 in) in diameter (fresh and fully mature), dark red, and contains a stone which encloses a single pepper seed.
The amount of piperine varies from 1–2% in long pepper, to 5–10% in commercial white and black peppers. [6] [7] Piperine can also be prepared by treating the solvent-free residue from a concentrated alcoholic extract of black pepper with a solution of potassium hydroxide to remove resin (said to contain chavicine, an isomer of piperine).

Piper, the pepper plants or pepper vines, is an economically and ecologically important genus in the family Piperaceae. It contains about 1,000–2,000 species of shrubs, herbs, and lianas, many of which are dominant species in their native habitat. The diversification of this taxon is of interest to understanding the evolution of plants.
The Naga Morich, with around 1 million SHU, [2] is primarily grown in India and Bangladesh. The Scoville scale is a measurement of pungency (spiciness or "heat") of chili peppers and other substances, recorded in Scoville heat units (SHU). It is based on the concentration of capsaicinoids, among which capsaicin is the predominant component.
Piperidine is an organic compound with the molecular formula (CH 2) 5 NH. This heterocyclic amine consists of a six-membered ring containing five methylene bridges (–CH 2 –) and one amine bridge (–NH–). It is a colorless liquid with an odor described as objectionable, typical of amines. [6]
Peperomiaceae Smith 1981. The Piperaceae (/ ˌpɪpəˈreɪʃiː /), also known as the pepper family, are a large family of flowering plants. The group contains roughly 3,600 currently accepted species in five genera. The vast majority of species can be found within the two main genera: Piper (2,171 species) and Peperomia (over 1,000 species).
Median lethal dose. In toxicology, the median lethal dose, LD50 (abbreviation for " lethal dose, 50%"), LC50 (lethal concentration, 50%) or LCt50 is a toxic unit that measures the lethal dose of a given substance. [1] The value of LD 50 for a substance is the dose required to kill half the members of a tested population after a specified test ...
There is a record from Tamil texts of Greeks purchasing large sacks of black pepper from India, and many recipes in the 1st-century Roman cookbook Apicius make use of the spice. The trade in spices lessened after the fall of the Roman Empire, but demand for ginger, black pepper, cloves, cinnamon and nutmeg revived the trade in later centuries. [19]
