Extraction of piperine and synthesis of piperic acid. Synthesis of piperonal

[the money]

PIPERINE FROM PEPPERCORNS

We take black peppercorns and use a microwave extraction process to extract pure piperine

--------------------------------
PIPERINE HYDROLYSIS TO PIPERINIC ACID

We hydrolyse piperine (extracted from peppercorns) in alkali solution to form piperinic acid and piperidine, and then isolate the pure products

PIPERONAL PREPARATION FROM PIPERINIC ACID

We demonstrate how to prepare piperonal, a beautifully aromatic aldehyde, from the oxidation of piperinic acid using potassium permanganate and periodate
