Description générale

Theobromine is an active bronchodilator drug ingredient used in the treatment of acute and chronic asthma. It is a naturally present alkaloid in a wide variety of foods and beverages, such as coffee, cocoa, tea, yerba mate and energizing drinks.

Application

Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.
Theobromine may be used as a reference standard for the determination of theobromine metabolites in human plasma and urine after consumption of soluble cocoa products with different methylxanthine contents by high-performance liquid chromatography and diode array detection (HPLC-DAD) method.

Actions biochimiques/physiologiques

Phosphosdiesterase inhibitor; weak adenosine receptor antagonist; diuretic; smooth muscle relaxant.

This work relates the development of an analytical methodology to simultaneously determine three methylxanthines (caffeine, theobromine, and theophylline) in beverages and urine samples based on reversed-phase high-performance liquid chromatography. Separation is made with a Bondesil C18 column using methanol-water-acetic acid
