High Speed Analysis of Piperine in Pepper using UHPLC

Download PDF August 25, 2017

Introduction

Piperine is a particular spicy constituent that is contained in Piperaceae plants and is effective in improving energy metabolism, circulation of the blood and excessive sensitivity to cold.

It is also known that piperine has an antibacterial action, an antiseptic action and an insecticidal action, and it is contained more in black pepper. In this application, piperine in pepper was analyzed using Ultra High-performance Liquid Chromatography with Photodiode Array Detection.

Results

Figure 1 shows the chromatogram and the contour plot of the piperine standard sample. A longer method analysis time was used than typical for UHPLC taking into consideration that the actual sample may require separation of other components.

Sample Preparation

Coarsely ground pepper was extracted using a Supercritical Fluid Extraction system and its extract was dissolved in 1 mL of Acetonitrile and diluted with Acetonitrile to 1/100 concentration. Then it was filtrated using 0.2 mm membrane filter.
