 | piperine Piperine is the alkaloid responsible for the pungency of black pepper along with chavicine (an isomer of piperine). Piperine is an alkaloid found naturally in plants belonging to the Piperaceae family, such as Piper nigrum L, commonly known as black pepper, and Piper longum L, commonly known as long pepper. Piperine is the major pungent substance in these plants and is isolated from the fruit of the black pepper and long pepper plants. Piperine comprises 1 to 99% of these plants. The term black pepper is used both for the plant Piper nigrum and the spice that is mainly in the fruit of the plant. Piperine is a solid substance essentially insoluble in water. It is a weak base that is tasteless at first, but leaves a burning aftertaste. Piperine belongs to the vanilloid family of compounds, a family that also includes capsaicin, the pungent substance in hot chili peppers. Its molecular formula is C17H19NO3, and its molecular weight is 285.34 daltons. Piperine is the trans-trans stereoisomer of 1-piperoylpiperidine. It is also known as (E, E)-1-piperoylpiperidine and (E, E)-1-[5-(1, 3-benzodioxol-5-y1)-1-oxo-2, 4-pentdienyl] piperidine. It is represented by the following chemical structure: Black pepper and long pepper have been used in Ayurvedic medicine for the treatment of various diseases. One such preparation is known by the Sanskrit name trikatu and consists of black pepper, long pepper and ginger. Another preparation, known by the Sanskrit name pippali, consists of long pepper. It is thought that piperine is one of the major bioactive substances of these Ayurvedic yuremedies. Black pepper has also been used in traditional Chinese medicine to treat seizure disorders. A derivative of piperine, antiepilepsirine, has also been used in China to treat seizure disorders. Some recent research suggests that piperine may enhance the bioavailability of some drugs and nutritional substances. | |||||
