Theophylline
A methylxanthine related to caffeine, first extracted from tea leaves in 1888 by German biochemist Albrecht Kossel: since the 1920s it has been used as a bronchodilator for asthma and COPD. This family brings together the active ingredient, pharmacopoeial impurities, labelled standards, nitrosamines and other impurities.
Did you know?Its name means tea leaf (from Thea, the old genus name for tea, and the Greek phyllon, leaf), yet brewed tea contains only traces of it: about 1 mg per litre.
