胡椒碱

Piperine is a naturally occurring bioactive alkaloid in pepper, which imparts pungency and bitter flavor to it.[1] It has demonstrated health benefits and exhibits therapeutic properties,[1] which include its role as an antimicrobial, antioxidant, antifungal,[2] immunomodulatory[1] and hepatoprotective agent.[2] The inhibition of drug-metabolizing enzymes in hepatic and pulmonary tissues, and the enhancement of drug bioavailability by this compound are reported.[2] It is also found to play an important role in reducing blood glucose, cholesterol and triglycerides.[1]

Piperine is an amide isolated from the plant, Piper longum.[3] It is a known inhibitor of hepatic and intestinal glucuronidation.[4] Piperine is found to exhibit pharmacological properties like antitumor, antipyretic and anti-inflammatory activities.[3]

Piperine may be used as an analytical reference standard for the quantification of the analyte in:

• Human plasma using high-performance liquid chromatography coupled to electrospray ionization tandem mass spectrometry (HPLC-ESI-MS/MS).[5]
• Piper nigrum extract using reversed phase high pressure liquid chromatographic method with UV detection (RP-HPLC-UV).[6]
• Food products using high-performance liquid chromatography with diode array detection (HPLC-DAD).[7]
